报告题目:Development of Lead-Zirconate-Titanate (PZT) Thin-Film  Microactuators for Inner Ear Hearing Rehabilitation

摘要:In this presentation, I will discuss design, fabrication, and testing of a piezoelectric-based intra-cochlear microactuator. Major challenges affecting its vibration performance include electric circuit layout, electrode size, residual stresses, piezoelectric coefficients measurements, and fabrication processes.  Experimental measurements indicate that the acoustic microactuator may experience a snap-through phenomenon. Finally, an acute animal test confirms that the intra-cochlear microactuator does produce pressure waves audible to the animal.
