This paper presents an electro-thermal micro-actuator based on polymer composite for dual-stage head positioning systems in hard disk drives (HDDs). This micro-actuator has a pair of benders, which are made of silicon–polymer composite. When electro-thermally activated by resistive heating, the comp...
