A High Precision Sound Sensor Inspired by Spider Legs
A team of researchers at Seoul National University has designed a highperformance sound sensor inspired by the sensor of spider legs. This innovation can be used to monitor heart function in detail and it could further be developed to detect minute physical vibrations.
Spiders "hear" each other and their environments through hairs on their bodies and through crackshaped slits (狭缝) on their legs. These hairs and slit organs pick up tiny vibrations in the air, which help them detect movement – helping them find prey or a potential mate, for example. This plex biological phenomenon was described by Peter Fratzl from Max Planck Institute of Colloids and Interfaces and Friedrich Barth from the University of Vienna. Based on their findings, the South Korean researchers created a mechanical version of the organ.
To test the sensor's performance, the researchers placed it on a violin. As a result, the sensor could
distinguish between the different notes being played. It correctly recorded the harmonic（和声的）frequency of each note in the piece. Another experiment was to stick the sensor on the necks of 10 people and ask them to say the words "go", "jump", "shoot" and "stop" – mands in a video game – more than 10 times into a microphone. Then they pared the microphone's recording to the sensor's recording. When the researchers played background noise at the same time, the microphone's spectrogram (声谱图) signals got really noisy, but the sensor remained accurate. Moreover, it could read out a subject's pulse if strapped to their wrist.
Korean researchers said the sensor is able to fit the sensor sensitivity for different applications by varying the density(密度) of cracks made in platinum (铂) film. For example, a sensor for measuring the heart rate does not need to be as sensitive as a version used for voice recognition.
The system could also be adapted to create more efficient earthquake detection systems. The researchers are also working to reduce the manufacturing cost by replacing platinum, the primary material for making the sensor, with copper or aluminium (铝).
1. What does the underlined part in Paragraph 2 refer to?
A. Movement can cause tiny vibrations in the air.
B. Spiders can find prey or a potential mate easily.
C. Spiders can hear the environments through their crackshaped slits.
D. Spiders have hairs on their bodies and crackshaped slits on their legs.
2. What have the South Korean scientists tested in their experiments?
A. How the sensor pronounces words.
B. How the sensor can record words and noise separately.
C. Whether the sensor can follow the mands in the video game.
D. Whether the sensor can distinguish between the different notes played by a violin.
3. What will the future research possibly focus on?
A. The sensor's reaction to different densities of sounds.
B. The efficiency of the sensor in detecting earthquakes.
C. New manufacturing materials that are more costfriendly.
D. Developing more types of sensors using copper or aluminium.
4. In which section of the newspaper can readers find the passage?
A. Health.
B. Science.
C. Business.
D. Education
