With its paper-thin construction, flexibility and force measurement ability, the FlexiForce force sensor can measure force between almost any two surfaces and is durable enough to stand up to most environments. FlexiForce has better force sensing properties, linearity, hysteresis, drift, and temperature sensitivity than any other thin-film force sensors. The "active sensing area" is a 0.375” diameter circle at the end of the sensor.The sensors are constructed of two layers of substrate. This substrate is composed of polyester film (or Polyimide in the case of the High-Temperature Sensors). On each layer, a conductive material (silver) is applied, followed by a layer of pressure-sensitive ink. Adhesive is then used to laminate the two layers of substrate together to form the sensor. The silver circle on top of the pressure-sensitive ink defines the “active sensing area.” Silver extends from the sensing area to the connectors at the other end of the sensor, forming the conductive leads.FlexiForce sensors are terminated with a solderable male square pin c onnector, which allows them to be incorporated into a circuit. The two outer pins of the connector are active and the center pin is inactive. The length of the sensors can be trimmed by Tekscan to predefined lengths of 2”, 4” and 6” or can be trimmed by the customer. If the customer trims the sensor, a new connector must be attached. This can be accomplished by purchasing staked pin connectors and a crimping tool. A conductive epoxy can also be used to adhere small wires to each conductor. The sensor acts as a variable resistor in an electrical circuit. When the sensor is unloaded, its resistance is very high (greater than 5 Meg-ohm); when a force is applied to the sensor, the resistance decreases. Connecting an ohmmeter to the outer two pins of the sensor connector and applying a force to the sensing area can read the change in resistance.Sensors should be stored at temperatures in the range of 15°F (-9°C) to 165°F (74°C) Standard FlexiForce SensorsThe Standard A201 sensor is available in the following force ranges:•Sensor A201-1 (0-1 lb. force range)•Sensor A201-25 (0-25 lb. force range)•Sensor A201-100 (0-100 lb. force range)** In order to measure forces above 100 lbs. (up to 1000 lbs), apply a lower drive voltage andreduce the resistance of the feedback resistor (1kΩ min.). See the sample drive circuit below.High-Temperature FlexiForce SensorsThe High-Temperature HT201 sensor is available in the following force ranges* (as tested with the sample drive circuit).•Sensor HT201-L Low: 0-30lb (133N) force range•Sensor HT201-H High: 0-100lb (445N) force range* In order to measure forces outside specified ranges, use recommended circuit and adjustdrive voltage and/or reference resistanceAPPLICATIONThere are many ways to integrate the FlexiForce sensor into an application. One way is to incorporate it into a force-to-voltage circuit. A means of calibration must then be established to convert the output into the appropriate engineering units. Depending on the setup, an adjustment could then be done to increase or decrease the sensitivity of the sensor.An example circuit is shown below. In this case, it is driven by a -5 V DC excitation voltage. This circuit uses an inverting operational amplifier arrangement to produce an analog output based on the sensor resistance and a fixed reference resistance (R F). An analog-to-digital converter can be used to change this voltage to a digital output. In this circuit, the sensitivity of the sensor could be adjusted by changing the reference resistance (R F) and/or drive voltage (VT);a lower reference resistance and/or drive voltage will make the sensor less sensitive, and increase its active force range.In the circuit shown, the dynamic force range of the sensor can be adjusted by changing the reference resistor (R F) or by changing the Drive Voltage (V O). Refer tothe Saturation section for additional information.SENSOR LOADING CONSIDERATIONSThe following general sensor loading guidelines can be applied to most applications, and will help you achieve the most accurate results from your tests. It is important that you read the Sensor Performance Characteristics section for further information on how to get the most accurate results from your sensor readings.SENSOR LOADINGThe entire sensing area of the FlexiForce sensor is treated as a single contact point. For this reason, the applied load should be distributed evenly across the sensing area to ensure accurate and repeatable force readings. Readings may vary slightly if the load distribution changes over the sensing area.Note that the sensing area is the silver circle on the top of the sensor only.It is also important that the sensor be loaded consistently, or in the same way each time.If the footprint of the applied load is smaller than the sensing area, the load should not be placed near the edges of the sensing area, to ensure an even load distribution.It is also important to ensure that the sensing area is the entire load path, and that the load is not supported by the area outside of the sensing area.If the footprint of the applied load is larger than the sensing area, it may be necessary to use a "puck." A puck is a piece of rigid material (smaller than the sensing area) that is placed on the sensing area to ensure that the entire load path goes through this area. The puck must not touch any of the edges of the sensing area, or these edges may support some of the load and give an erroneous reading.The FlexiForce sensor reads forces that are perpendicular to the sensor plane. Applications that impart "shear"forces could reduce the life of the sensor. If the application will place a "shear" force on the sensor, it should be protected by covering it with a more resilient material.If it is necessary to mount the sensor to a surface, it is recommended that you use tape, when possible. Adhesives may also be used, but make sure that the adhesive will not degrade the substrate (polyester) material of the sensor before using it in an application. Adhesives should not be applied to the sensing area; however, if it is necessary, ensure that the adhesive is spread evenly. Otherwise, any high spots may appear as load on the sensor.SATURATIONThe Saturation force is the point at which the device output no longer varies with applied force. The saturation force of each sensor is based on the maximum recommended force specified by Tekscan, which is printed on the system packaging or the actual sensor, along with the "Sensitivity."02/05/09 FlexiForce Sensor User Manual (Rev G)The saturation value is based on using the circuit and the values shown in the example circuit in the ‘Application’ section. In this example, the saturation force (maximum force) of each sensor is related to the RF (reference resistance), and can be altered by changing the sensitivity. The sensitivity of the sensor would be adjusted by changing the reference resistance (RF); a lower reference resistance will make the system less sensitive, and increase its active force range.It is essential that the sensor(s) do not become saturated during testing.CONDITIONING SENSORSExercising, or Conditioning a sensor before calibration and testing is essential in achieving accurate results. It helps to lessen the effects of drift and hysteresis. Conditioning is required for new sensors, and for sensors that have not been used for a length of time.To condition a sensor, place 110% of the test weight on the sensor, allow the sensor to stabilize, and then remove the weight. Repeat this process four or five times. The interface between the sensor and the test subject material should be the same during conditioning as during calibration and actual testing.IMPORTANT! Sensors must be properly conditioned prior to calibration and use.CALIBRATIONCalibration is the method by which the sensor’s electrical output is related to an actual engineering unit, such as pounds or Newtons. To calibrate, apply a known force to the sensor, and equate the sensor resistance output to this force. Repeat this step with a number of known forces that approximate the load range to be used in testing. Plot Force versus Conductance (1/R). A linear interpolation can then be done between zero load and the known calibration loads, to determine the actual force range that matches the sensor output range.Resistance Curve: Conductance Curve:CALIBRATION GUIDELINESThe following guidelines should be considered when calibrating a sensor:•Apply a calibration load that approximates the load to be applied during system use, using dead weights or a testing device (such as an MTS or Instron). If you intend to use a "puck" during testing, also use it when calibrating the sensor. See Sensor LoadingConsiderations for more information on using a puck.•Avoid loading the sensor to near saturation when calibrating. If the sensor saturates at a lower load than desired, adjust the "Sensitivity."•Distribute the applied load evenly across the sensing area to ensure accurate force readings. Readings may vary slightly if the load distribution changes over the sensingarea.•Sensors should be calibrated at the same temperature for which testing will occur. This is especially important for High-Temp Sensors, as these sensors have a wide operatingtemperature range. If multiple temperatures are used during testing, calibrate the sensors at those same multiple temperatures.Note: Read the Sensor Performance Characteristics section before performing a Calibration.SENSOR PERFORMANCE CHARACTERISTICSThere are a number of characteristics of sensors, which can affect your results. This section contains a description of each of these conditions, and recommendations on how to lessen their effects.REPEATABILITYRepeatability is the ability of the sensor to respond in the same way to a repeatedly applied force. As with most measurement devices, it is customary to exercise, or "condition" a sensor before calibrating it or using it for measurement. This is done to reduce the amount of change in the sensor response due to repeated loading and unloading. A sensor is conditioned by loading it to 110% of the test weight four or five times. Follow the full procedure in the Conditioning Sensors section.LINEARITYLinearity refers to the sensor’s response (digital output) to the applied load, over the range of the sensor. This response should ideally be linear; and any non-linearity of the sensor is the amount that its output deviates from this line. A calibration is performed to "linearize" this output as much as possible. FlexiForce standard sensors are linear within +/- 3%. FlexiForce High-Temperature sensors have a linearity that is 1.2% of full scale.HYSTERESISHysteresis is the difference in the sensor output response during loading and unloading, at the same force. For static forces, and applications in which force is only increased, and not decreased, the effects of hysteresis are minimal. If an application includes load decreases, as well as increases, there may be error introduced by hysteresis that is not accounted for by calibration. DRIFTDrift is the change in sensor output when a constant force is applied over a period of time. If the sensor is kept under a constant load, the resistance of the sensor will continually decrease, and the output will gradually increase. It is important to take drift into account when calibrating the sensor, so that its effects can be minimized. The simplest way to accomplish this is to perform the sensor calibration in a time frame similar to that which will be used in the application. TEMPERATURE SENSITIVITYIn general, your results will vary if you combine high loads on the sensor with high temperatures. To ensure accuracy, calibrate the sensor at the temperature at which it will be used in the application. If the sensor is being used at different temperatures, perform a calibration at each of these temperatures, save the calibration files, then load the appropriate calibration file when using the sensor at that temperature.SENSOR LIFE / DURABILITYSensor life depends on the application in which it is used. Sensors are reusable, unless used in applications in which they are subjected to severe conditions, such as against sharp edges, or shear forces. FlexiForce sensors have been successfully tested at over one million load cycles using a 50 lb. force.Rough handling of a sensor will also shorten its useful life. For example, a sensor that is repeatedly installed in a flanged joint will have a shorter life than a sensor installed in the same joint once and used to monitor loads over a prolonged period. After each installation, visually inspect your sensors for physical damage.It is also important to keep the sensing area of the sensor clean. Any deposits on this area will create uneven loading, and will cause saturation to occur at lower applied forces.SENSOR PROPERTIESSTANDARD FLEXIFORCE SENSOR (MODEL A201)Sensor PropertiesThickness 0.008(0.208mm)Length 8” (203 mm) 6” (152 mm) 4” (102 mm) 2” (51 mm)Width 0.55” (14 mm)Sensing Area 0.375” (9.53 mm) diameterConnector 3-pin male square pin (center pin is inactive) Typical PerformanceForce Ranges 0-1 lb (4.4 N)0-25 lbs (110 N) 0-100 lbs (440 N)*Operating TemperatureRange15°F to 140°F (-9°C to 60°C)Linearity (Error) +/- 3%Repeatability +/- 2.5% of full scale (conditioned sensor, 80% force applied) Hysteresis <4.5% of full scale (conditioned sensor, 80% force applied)Drift <5% per logarithmic time scale (constant load of 90% sensor rating) Response Time <5 microsecondsOutput Change/Degree F Up to 0.2% (~0.36% / °C).Loads <10 lbs, operating temperature can be increased to 165°F (74°C).HIGH-TEMPERATURE FLEXIFORCE SENSOR (MODEL HT201) Sensor PropertiesThickness 0.008”(0.203mm) Length 7.75” (197 mm)Optional: 6” (152 mm)Trimmed: 4” (102 mm)Lengths: 2” (51 mm)Width 0.55” (14 mm)Sensing Area 0.375” (9.53 mm) diameterConnector 3-pin Male Square Pin (center pin is inactive) Substrate Polyimide (ex: Kapton)Typical PerformanceForce Ranges 0-30 lbs (133N)0-100 lbs (445N)Operating Temperature Range 15°F to 400°F (-9°C to 204°C)Repeatability +/- 3.5% of full scaleLinearity +/- 1.2% of full scaleHysteresis 3.6% of full scaleDrift 3.3% per log timeOutput Change/Degree F 0.16%。

FSS系列低档度力量传感器说明书
FSS SeriesLow Profile Force SensorDESCRIPTIONThe FSS Series Force Sensor provides precise, reliable force sensing performance in a compact, commercial-grade package at a cost effective price. The sensor features a proven sensing technology that uses a specialized piezoresistive,micromachined silicon sensing element. The low power,unamplified, uncompensated Wheatstone bridge circuit design provides inherently stable mV outputs over the force range.Force sensors operate on the principle that the resistance of silicon-implanted piezoresistors will increase when theresistors flex under any applied force. The sensor concentrates force from the application, through the stainless steel ball, directly to the silicon-sensing element. The amount ofresistance changes in proportion to the amount of force being applied. This change in circuit resistance results in a corresponding mV output level change.The sensor package design incorporates patented modular construction.

Flexiforce传感器分类介绍及其应用
一、Flexiforce 传感器
Flexiforce是一种超薄和挠性印刷电路，可很方便集成多种运用。
由于Flexiforce 像纸一样薄的结构，可弯曲和测力特性可用来测两表面之间的压力，并且能够在一些特殊环境进行测力。
Flexiforce 比其它薄膜测力产品有更好的特性、线性、磁滞、飘移、温度灵敏度。
传感的有效区域是传感器末端的直径为0.95cm的圆。
Flexiforce 由两层衬底构成。
这种衬底由聚脂纤维薄膜组成(高温传感器用的是聚酰亚胺构成)。
在每一层上运用一种导体材料(银)，再加一层对压力敏感的墨水。
然后用粘合剂把两层衬底压在一起，形成了传感器。
墨水外的银边表示了对压力敏感的区域。
从敏感区域引出两个银线作为导线。
Flexiforce 传感器尾端选配一个可焊接的公的方针接头以方便连接到电路。
两边的输出线是有效的，中间的是无效的。
传感器的长度可选6cm、12cm、18cm或由客户定制。
在电路中传感器相当于一个可变电阻。
当没有负载时，传感器呈高阻状态(>5MΩ)，当有负载时，电阻下载。
接一个欧姆表可以看见当在敏感区域施加外力时电阻的变化。
Flexiforce 需保存在温度-9°C74°C之间。
二、标准Flexiforce传感器
标准A201传感器有下列量程供选择：
Sensor A201-1 (0-1 lb)(0-4.5N)
Sensor A201-25 (0-25 lb)(0-112.5N)
Sensor A201-100 (0-100 lb)*(0-445N)
如果要测量大于100lb的力可降低供电电压和降低反馈电阻(最小1KΩ min)可参看驱动电路图。
三、高温Flexiforce传感器
高温HT201传感器有下列量程供选择：
HT201-L Low: 0-30lb (133N)
HT201-H High: 0-100lb (445N)
四、运用
Flexiforce传感器有非常多的用法。
典型的运用就是把检测的压力转化成电压信号输出。
校准也必须去做，就是把输出信号和相应的压力的大小对应。
根据配置，灵敏度依然可以进行调节。
典型电路如下图：
在该电路中，用+/-5V的电压激励，反相比例放大电路结构，基于传感器电阻和反馈电阻的变化产生模拟信号输出。
模数转换器也可把模拟信号转为数字信号输出。
灵敏度由反馈电阻Rf和电压VT 进行调整。
降低反馈电阻和电压会使灵敏度下降，但可使量程增大。
用途简介：
医疗用途：牙齿咬合力测量;病人组织插管测力;临床大夫触力检验测量;心肺复苏、人工呼吸救护训练(CPR)(位置、深度、频率)触力测量;诊断设备研究肌肉关节活动情况;发音矫正;智能鞋垫进行走路平衡能力测控(老年人走路摔倒报警);重症病人，老人监护报警等。
汽车运用：乘员探测;安全气囊对乘员压力;拖车刹车控制。
休闲娱乐运用：体育用具;健身器材;握力测量;GOLF训练。
工业运用：安全装置;包装与密封;自动化生产;滚动轴承;电缆卷轴;电脑芯片。
其它：动物或人类咬力测量;触力设备;抓力;库存管理;设备监控;机器人;等等。
传感器载荷考虑因素
下面的传感器负载运用指导适合任何运用，以帮助您取得精确的测量结果。
后面传感器性能参数表对您获取准确的传感器数据也是至关重要的。
一、传感器负载
Flexiforce传感器整个传感区域被当成一个独立的接触点。
因此，负载应均匀分布在传感区域以保证准确和重复的测力数据。
如果负载分布改变就会轻微地改变传感器的读数。
(传感器传感区域就是银线包围中间的部分)
施加负载的持续也很重要，并保证每次是同样的方式;
不要让传感区域外面的部分也支持负载;
如果要测的负载大于传感区域，那么可使用一个圆盘(一般由硬材料构成，并小于传感区域)，使负载通过圆盘压住传感区域，注意不要压住传感区域的边缘。
加的力需垂直于传感区域的平面。
如果施加剪切的力会降低传感器的寿命。
如非要加这样的力，需要有弹性材料进行保护。
如果把传感器放在一个表面，可使用带子或胶水。
注意不要把胶水沾在了传感区域，如果一定要的话，要保证涂的均匀，否则一些高点会变成负载。
二、饱和值
饱和值就是输出不再随施加的力而变化的点。
每个传感器的饱和值会印在包装盒或传感器上和灵敏度在一起。
饱和值在上面的运用电路中和反馈电阻Rf有关，当降低反馈电阻Rf时可降低灵敏度，但可增大量程，也就是可增大饱和值。
注意在测试中不要让外力到达饱和值。
三、传感器适应使用
在测试或校准前，让传感器适应或适用对取得准确的测量数据是必须的。
它可以帮助减少磁滞和飘移。
对于新传感器需要让它用一段时间以适应环境。
让传感器适应使用，可采用110%的力加在传感器上，让传感器稳定，再移动负载。
重复这个过程四到五次。
传感器和测试材料的接触面需保持和测试和校准时一致。
(重要：在校准和使用前，传感器必须经过适应使用)
校准
校准就是让传感器的输出和真正的测力值建立一个对应关系如磅或牛顿。
校准时，可采用一已知力加在传感器上，然后把传感器的阻值和力值对应起来。
用一些和测试时接近的力值，重复进行这个校准的过程。
力和电导(1/R)的对应图如下。
一个线性的对应关系可从图中看出。
然后，你可用传感器的输出值来决定你的测力的大小了

电导曲线
校准指导：
在校准传感器可参考下列指导：
有与实际测试中相近的力来进行校准。
(用已知的力，如砝码或测力机)。
如在校准中用圆盘那么在测试中也用。
在校准时避免和测力饱和值接近，如在很少的力就饱和了，那么就调整灵敏度。
在感应区域内，均匀放置负载。
负载分布改变，结果会有轻微变动。
测试和校准时温度需保持一致。
传感器性能指标描述：
有一些性能指标会影响到传感器的测量结果。
这里对每个指标进行一些描述，以帮助减少不必要的影响。
重复性：对于同样多次施加的力，传感器能保持显示数据的一致性。
通常，我们建议通过对传感器进行适应“训练”后，再进行测试或校准。
线性：指传感器针对负载的响应偏移超过了传感器的实际量程。
校准可以尽量使输出保持线性。
Flexiforce传感器的输出线性在+/- 3%以内。
Flexiforce高温传感器的线性可以做到满量程的1.2%。
磁滞：在加负载和移除负载时，传感器的实际输出值的差异。
在静态时，在负载增加时，磁滞是非常小的。
但在负载一会小一会大时，会有磁滞引起的误差。
飘移：指在施加力后一段时间，输出会有相应的变化。
如果在一个固定的负载下，输出电阻持续减少，输出就会慢慢增大。
在校准时考虑到飘移的因素，可减少其影响。
最简单的方法是保证校准时和实际测试时的时间段一致。
温度灵敏度：通常，输出在大负载情况下会随温度升高而变化。
为保证准确性，校准和测试时要保持一致温度。
如果不一致，最好在不同的温度下都做一校准，并以保存备用。
寿命：寿命是根据你的使用情况而定。
一般传感器可以反复使用，除了在一些极端情况下：如承受硬边或冲击力。
经测试，对一个50lb的Flexiforce传感器可以使用一百万次。
物理损伤自然会降低它的寿命。
保持传感区域清洁，否则脏物会引起测量不准，及过早地进入饱和状态。
