Development of Sensor New Technology

Sensor is one kind component which can tansform the physical quantity, ch emistry quantity and the biomass into electrical signal. The output signal has the different forms like the voltage, the electric current, the frequency, the pulse and so on, which can satisfy the signal transmission, processing, recording, demon stration and control demands. So it is the automatic detection system and in the a utomatic control industry. If automatic Technology is used wider, then sensor is more important. In information age, the information industry includs informatio n gathering, transmission, process three parts, namely sensor technology, com munication, computer technology. Because of ultra large scale integrated circuit’s rapid development after having been developed ,Modern computer technology and communication, not only requests sensor precision, reliability, speed of res ponse and gain information content request more and more high, but also reques ts its cost to be inexpensive. The obvious traditional sensor is eliminated gradual ly because of the function, the characteristic, the volume, the cost and so on. As world develop many countries are speeding up to the sensor new technology’s r esearch and the development, and all has obtained the enormous breakthrough. Now the sensor new technology development, mainly has following several aspe cts:

Firstly, discovering and using.

Using the physical phenomenon, the chemical reaction, the biological effe ct as the sensor principle therefore the researches which discovered the new phe nomenon and the new effect are the sensor technological improving ways .it is i mportantstudies to develope new sensor’s the foundation. Japanese Sharp Corpo ration uses the superconductivity technology to develop successfully the high te mperature superconductivity magnetic sensor and get the sensor technology sign

ificant breakthrough. Its sensitivity is so high and only inferior in the supercond uctivity quantum interference component. Its manufacture craft is far simpler tha n the superconductivity quantum interference component. May use in magnetis m image formation technology.So it has the widespread promoted v

alue.

Using the immune body and the antigen meets one another compound whe n the electrode surface.It can cause the electrode potential change and use this p henomenon to be possible to generate the immunity sensor. The immunity senso r makes with this kind of immune body may to some organism in whether has th is kind of anti- original work inspection. Like may inspect somebody with the he patitis virus immune body whether contracts the hepatitis, plays to is fast, the ac curate role. The US UC sixth branch has developped this kind of sensor. Secondly, using the new material.

The sensor material is the important foundation for sensor technology, bec ause the materials science is progressive and the people may make each kind of new sensor. For example making the temperature sensor with the high polymer t hin film; The optical fiber can make the pressure, the current capacity, the tempe rature, the displacement and so on the many kinds of sensors; Making the pressu re transmitter with the ceramics. The high polymer can become the proportion a dsorption and the release hydrone along with the environment relative humidity size. The high polymer electricity lies between the constant to be small, the hydr one can enhance the polymer the coefficient of dielectrical loss. Making the cap acitor the high polymer dielectric medium, determines the electric capacity capa city the change, then obtains the relative humidity. Making the plasma using this principle to gather the legitimate polystyrene film temperature sensor below, it has the characteristic:

Measured the wet scope is wide;

The temperature range is wide, may reach -400 ℃ ~ +1,500 ℃;

The speed of response is quick, is smaller than 1S;

The size is small, may use in the small space measuring wet;
