Micro high power linear piezoelectric actuator

平滑冲击驱动机构是一种紧凑型线性压电驱动器，已得到实际应用。在这项研究中，我们提出了一种谐振型SIDM，它使结构更简单，易于小型化，因为它利用一个单一的PZT板，而不是一个多层的PZT。此外，高功率输出操作成为可能。作为基础研究，我们研究了这种R-SIDM定子换能器的设计策略，并以尺寸为10 mm长和2 mm宽的换能器演示了所提出的原理。

Smooth Impact Drive Mechanism(SIDM) is one of the compact linear piezoelectric actuators, which has been practically used. In this study, we propose a resonant-type SIDM, which enables much simpler structure and easy miniaturization because it utilizes a single PZT plate instead of a multi-layered PZT. Furthermore high power output operation becomes possible. As a fundamental research, we studied about the design strategy for this R-SIDM stator transducer and demonstrated the proposed principle with the transducer whose dimensions were 10 mm long and 2 mm width.
