Abstract
The development of thermal micro-actuators on printed circuit boards is described. The fabricated metal actuators are shown to have similar displacement characteristics when compared with silicon-based devices described in the literature. The actuators are benchmarked with respect to power consumption, stroke, and response time. It is further demonstrated that simple analytical estimates for the response time are in good agreement with the experimental measurements and finite element analysis. The thermal cooling transient times are captured using a two-step constant-current excitation method. The fabrication process and potential application areas of the developed device are also provided.
