One option is to use sequentially triggered vertebrae made of electroactive polymers, whose shape is modified by applying a voltage. 現在一種選擇是繼續使用由電聚合物制造的觸發(fā)椎骨，其形狀是通過(guò)觸發(fā)電壓而改變的。
The trigger wheel rotates with engine RPMs and causes the speed sensor, or pickup oil, to produce triggering voltage pulses that correspond to engine speed and piston position. 觸發(fā)葉輪隨發(fā)動(dòng)機轉速而旋轉，使得轉速傳感器或拾波線(xiàn)圈產(chǎn)生與發(fā)動(dòng)機轉速和活塞位置相對應的觸發(fā)電壓脈沖。
