Ultrasonic drives are one research area of the IKFF. Especially the excitation of standing waves with vibrating piezo ceramics, including friction pins looks very promising to generate elliptical trajectories. The hemispherical structural shape of the piezo ceramics is under analysis to design multidimensional resonators, by varying the piezo electric material and geometry optimization, to achieve very strong and compact drives for XYPhi-directions. The contact free measurement and movement analysis of the friction pin should be performed with the requested Laser-Doppler-Scanning-Vibrometer.

超声波驱动器是IKFF的研究领域之一。特别是用振动压电陶瓷（包括摩擦销）激发驻波看起来非常有希望产生椭圆轨迹。压电陶瓷的半球形结构形状正在分析中，通过改变压电材料和几何优化来设计多维谐振器，以实现XY方向的非常强大和紧凑的驱动器。摩擦销的无接触测量和运动分析应使用要求的激光多普勒扫描振动计进行。
