SDIO Workshop on Piezoelectric Ceramic Actuators for Space Applications Held in Alexandria, Virginia on 25 February 1992
Abstract
Lt. Col. Michael Obal of the SDIO Materials and Structures Office sponsored this workshop on piezoceramic actuators for space applications. Its purpose was threefold: to promote communications among the appropriate groups; to focus and prioritize issues for near-team improvements in actuator performance; and to identify and suggest research plans to obtain such improvements. Presentations were given by representatives from each of three invited groups: end users/designers; materials researchers; and materials/device manufacturers. Issues identified in the workshop seemed to fall into three major categories: (1) piezoceramic material performance limitations; (2) distribution of properties of vendor-supplied materials; and (3) actuator applications. Performance limitation issues include, for example, d(31) vs. d(33) performance, displacement/volt, fatigue life at high strains, and tensile strain-to-failure. Property distribution issues include composition, capacitance, and surface finish. Actuator application issues include ceramic material/actuator fabrication, material handling, application of electrodes to actuator, and post-composite fabrication actuator performance.
