Abstract

Electrothermal bimorphs are known for large vertical displacement. In this paper, an electrothermal bimorph actuator with a multi-section structure is proposed to generate large in-plane displacement with the vertical motion minimized. The device has been fabricated and tested. With a 500 μm × 500 μm micro-platform attached at the end of the actuator, the maximum in-plane displacement reaches 86 μm at just 4.5 Vdc, while the corresponding out-of-plane displacement is only a quarter of the in-plane one. This device has excellent in-plane moving ability and can be used as part of multiple degrees of freedom MEMS actuators, which makes it a great potential in applications such as optical image stabilization.
