传感器新技术的发展-----外文翻译.docVIP

Development?of?Sensor?New?Technology Sensor is one kind component which can tansform 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 includs 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: Firstly, discovering and using. ??? Using the physical phenomenon, the chemical reaction, the biological effect as the sensor principle therefore the researches? which discovered the new phenomenon and the new effect are the sensor technological improving ways .it is importantstudies to develope new sensor’s the foundation. Japanese Sharp Corporation uses the superconductivity technology to develop successfully the high temperature superconductivity magnetic sensor and get the sensor technology significant breakthrough. Its sensitivity is so high and only inferior in the superconductivity qua
