板極變壓器 的英文怎麼說
中文拼音 [bǎnjíbiànyāqì]
板極變壓器
英文
plate transformer-
Mems ( micro electromechanical system ) has become one of the most rapidly development technologies. along with the rapid development of mems techniques, capacitive sensor is used widely whose capacitance changes small, which has put forward the new request to the measurement technique. the common measure for capacitance measurement is that convert capacitance to voltage, electric current or frequency. the area of polar plate of the capacitor becomes smaller and smaller, and the total capacitance of micro capacitive sensor is usually several pico farad only. as a result, its change amount is smaller
Mems （ microelectromechanicalsystem ）近年來發展最快的技術之一，隨著mems技術的快速發展，電容式加速度計的電容變化變化量越來越小，對檢測技術提出了新的要求。在電容式傳感器中，常用電容檢測電路是將其轉換為電壓、電流或者頻率信號。目前的微型電容傳感器的極板面積變得越來越小，電容總量只有幾個pf ，變化量就更小。The results show that the elastic membrane thickness, actuator span and gap spacing have a strong effect on the deflection, the actuator undergoes the deflection increasing nonlinearly at voltages below pull - in voltage and snap through instability at voltages above pull - in voltage when subjected to a voltage ramp, the re - set time and repeatability are attractive when the actuated voltage is set to zero
結果表明，驅動器的彈性薄板厚度、跨度和電極間距明顯影響變形位移；驅動器的變形位移隨驅動電壓的增加出現穩定的非線性增加和不穩定的「拉入」現象；驅動電壓撤除后鏡面回復時間短，重復性好。
