The experimental driving platform is NPX25A Nanometer positioning platform, it is a closed loop and monopodium Nanometer locator with 25 Run Internet deals.The driving voltage signal is required by the function generator, amplified by the amplifier and send to the piezoelectric material.
Due to the inverse piezoelectric effect of the piezoelectric material [7], the piezoelectric material produces a relatively large deflection displacement detected by the laser displacement sensor, collect the input voltage and displacement deflection using the data acquisition card, and they are simultaneously fed into the computer for processing.
