SBIR 95-1 SOLICITATION
INJECTION MOLDED, HIGH PERFORMANCE PIEZOELECTRIC ACTUATORS
Materials Systems Inc. (MSI) proposes to adapt its net shape ceramics injection molding technology to fabricate a new family of reliable, high performance piezoelectric actuators. The new family of actuators is based on a monolithic, multi-element PZT component, shown schematically in Figure 1. Several different actuator variations can be produced from this PZT component utilizing different poling and electroding arrangements, including: (a) large-scale (50 mm or more long) multilayer "stacks" (d33 actuation) and (b) large displacement piezoelectric "springs" (d33, d31, or d15 actuation). These new actuator configurations offer enhanced force-displacement characteristics compared with currently available devices and will extend the capabilities of smart materials and structures in aerospace, automotive, machine tool, and many other applications. These actuators will also be able to operate over wider frequency and temperature ranges than current devices. Furthermore, these innovations will be achieved using fabrication technologies that have already been demonstrated by MSI to be inherently low cost in production.
Potential Commercial Applications:
Applications include: active vibration damping (struts and engine mounts), noise suppression (interior and engine noises), acoustic camouflage, actuated structures, precision pointing (optical and radio frequency payloads), reconfigurable surfaces (flutter suppression), and structural health monitoring.
