【正文】 n industry includes information gathering, transmission, process three parts, namely sensor technology, munication, puter technology. Because of ultra large scale integrated circuit’s rapid development after having been developed Modern puter technology and munication, 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: 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 important studies to developed new sensor’s the foundation. Japanese Sharp Corporation uses the superconductivity technology to develop successfully the high temperature superconductivity magic sensor and get the sensor technology significant breakthrough. Its sensitivity is so high and only inferior in the superconductivity quantum interference ponent. Its manufacture craft is far simpler than the superconductivity quantum interference ponent. May use in magism image formation technology. So it has the widespread promoted value. Using the immune body and the antigen meets one another pound when the electrode surface. It can cause the electrode potential change and use this phenomenon to be possible to generate the immunity sensor. The immunity sensor makes with this kind of immune body may to some anism in whether has this kind of ant original work inspection. Like may inspect somebody with the hepatitis virus immune body whether contracts the hepatitis, plays to is fast, the accurate role. The US UC sixth branch has developed this kind of sensor. The sensor material is the important foundation for sensor technology, because 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 thin film。我國(guó)在這方面的研究與開發(fā)還很落后,主要是因?yàn)槲覈?guó)半導(dǎo)體集成電路工藝水平有限。 把傳感器、信號(hào)調(diào)節(jié)電路、單片機(jī)集成在一芯片上形成超大規(guī)模集成化的高級(jí)智能傳感器 。另一特點(diǎn)是能敏感微小被測(cè)量,可制成血壓壓力傳感器。當(dāng)環(huán)境溫度變化時(shí),兩個(gè)諧振梁頻率和幅度變化相同,將兩個(gè)頻率差后,其相同變化量就能夠相互抵消。 半導(dǎo)體技術(shù)中的加工方法有氧化、光刻、擴(kuò)散、沉積、平面電子工藝,各向?qū)愿g及蒸鍍,濺射薄膜等,這些都已引進(jìn)到傳感器制造。光纖傳感器日本處于先進(jìn)水平。德國(guó) E+H 公司和美國(guó) Kahlo 公司產(chǎn)品處于領(lǐng)先地位。 陶瓷電容式壓力傳感器是一種無(wú)中介液的干式壓力傳感器。高分子聚合物能隨周圍環(huán)境的相對(duì)濕度大小成比例地吸附和釋放水分子。如用肝炎病毒抗體可檢查某人是否患有肝炎,起到快速、準(zhǔn)確作用。它的制造工藝遠(yuǎn)比超導(dǎo)量子干涉器件簡(jiǎn)單。顯然傳統(tǒng)傳感器因功能、特性、體積、成本等已難以滿足而逐漸被淘汰。如果把計(jì)算機(jī)比作大腦,那么傳感器則相當(dāng)于五官,傳感器能正確感受被測(cè)量并轉(zhuǎn)換成相應(yīng)輸出量,對(duì)系統(tǒng)的質(zhì)量起決定性作用。輸出信號(hào)有不同形式,如電壓、電流、頻率、脈沖等,能滿足信息傳輸、處理、記錄、顯示、控制要求,是自動(dòng)檢測(cè)系統(tǒng)和自動(dòng)控制系統(tǒng)中不可缺少的元件?,F(xiàn)代的計(jì)算機(jī)技術(shù)和通 信技術(shù)由于超大規(guī)模集成電路的飛速發(fā)展,而已經(jīng)充分發(fā)達(dá)后,不僅對(duì)傳感器的精度、可靠性、響應(yīng)速度、獲取的信息量要求越來(lái)越高,還要求其成本低廉且使用方便。日本夏普公司利用超導(dǎo)技術(shù)研制成功高溫超導(dǎo)磁性傳 感器,是傳感器技術(shù)
