Development of Sensor New Technology
Sensor is one kind component, which can transform the physical quantity, chemistry 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, demonstration and control demands. So it is the automatic detection system and in the automatic control industry. If automatic Technology is used wider, then sensor is more important In Information age, the information industry includes information-gathering, transmission, process three parts, namely sensor technology, communication, 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 response and gain information content request more and more high, but also requests its cost to be inexpensive. The obvious traditional sensor is eliminated gradually 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 research and the development, and all has obtained the enormous breakthrough. Now the sensor new technology development, mainly has following several aspects:
