Abstract

Not Available A miniature high-strain actuator is proposed that has low internal stresses and high efficiency while using single crystal piezoelectric (PZT) materials. Single crystal PZT materials provide at least 400 percent more strain than polycrystalline materials and make it possible to produce significantly smaller actuators while maintaining the same performance. Burleigh proposes to develop new design and assembly methods that that compensate for the higher strain and lower stiffness of single crystal PZT by using anisotropic composite material bonds, electrodes and interfaces. By using these anisotropic composite materials the internal stresses are minimized and the output efficiency maximized. At least these composite material concepts will be considered: (1) micro-machining (MEMS) thin arrays of support posts connected by flexible links, (2) mixing spherical particles with polymer adhesive prior to bonding, and (3) dicing thin disks from unidirectional composite rods. All these approaches have the same objective of maximizing the d33 stiffness and d31 yield strain. Practical manufacturing solutions will be investigated and identified. In the option phase, a single crystal PZT stack and flex- tensional amplifier will be designed and constructed, using the selected composite electrodes and bonds, and fully tested to characterize motion, creep, hysteresis, non-linearity, force, stiffness and resonant frequency.
