To further improve the imaging capability of this kind of probe, structure design and measurement improvements were studied and presented in this work, including new detection scheme based on simple differential measurement and using locally doped piezoresistors at maximum strain locations. Experimental results showed that with these improvements, the feedthrough coupling effect between driving and sensing is effectively eliminated and the measurement sensitivity is improved by at least 10 times.Lire moins >
