000184516 520__ $$aThis work focuses on some promising applications of polyvinylidene fluoride (PVDF) based bimorph actuators in microengineering. The actuator of several centimeters in length and 100 mu m in thickness takes advantage of the structural and electromechanical capabilities of the PVDF. These characteristics make the proposed PVDF based bimorph ideal for a laser scanner/switcher where high speed laser beam manipulation is feasible. This domain requires light and efficient actuators capable of actuating the mirror surface at kHz frequency range and having a weight of less than 200 mg and volume of less than 150 mm(3). Analytical and finite element (FE) modeling were used to design the bimorph actuator with an attached mirror on the tip. Results of the modeling were also used to establish dimension criteria for the proposed bimorphs with an attached mirror. Some clean and gray room processing was needed to fabricate the bimorph actuators. Static and dynamic characterization was carried out to validate the response of the proposed actuator. Other bimorph based configurations were analyzed and compared to the proposed one. Results indicate that the PVDF bimorph actuator responds conveniently in a range up to 3 kHz for beam scanning tasks. The same principle may be implemented to 2 DoF actuators. Results obtained from modeling tools indicate a similar performance in terms of displacement. In addition, due to the intrinsic properties of the PVDF, the actuation system is compact which is advantageous for other domains such as biomedical and aerospace. (C) 2012 Elsevier B.V.
