Flexible Fabrication of High Performance Piezoelectric Actuators by Injection Molding
Abstract
Specific program accomplishments include: Designed, fabricated, and tested a subscale volume actuator, offering ruggedness, high volume efficiency, and easily redirected actuation direction. Designed, scaled-up, fabricated, and tested over 200 unidirectional serpentine actuator elements, 25x25x 1 mm in size. Demonstrated serpentine actuator with 4 times free displacement improvement over d(33) multilayer devices. Designed and evaluated an internally amplified multilayer actuator, with efficiencies as high as 24%. Designed, fabricated, and tested stacked co-fired multilayer actuators manufactured with MSI-53HD and PNN-1 materials. Developed a new high energy density actuator material, with potentially 1.7 and 2.8 times higher microstrain and energy density compared with state-of-the-art COTS piezoelectric ceramic materials. Showed the potential for meeting the helicopter rotorblade actuation requirements performance with the internally amplified multi- layer actuator with the new high energy density material.
