疊層式壓電驅動器采用多層壓電陶瓷薄片按照一定極性方向組合而成，在直流電壓控制下沿長度方向伸縮，具有位移分辨率高（可達到納米級）、驅動力大、響應速度快等特點。可應用于納米定位控制臺、密光學顯微鏡、激光調諧、高速閥門等微位移驅動裝置

Stack actuators utilize super thin piezo-ceramic wafers, bonded in a stack to provide high sensitivity, rapid response sensing and low driver voltage displacement and force actuation, both with outstanding cycle rates and superb reliability. They are used widely for the accurate displacement control of equipment, and are commonplace in optical, semiconductor, aviation, medical and genetic engineering fields.
