TECHNICAL ABSTRACT ( Limit 2000 characters, approximately 200 words)
TRS Technologies proposes novel single crystal piezomotors for large torque, high precision, and cryogenic actuation with capability of position set-hold with power-off for passive optics platforms. The proposed concept will advance the state-of-art cryogenic rotary motors considering the excellent cryogenic properties of single crystal piezoelectric. This material exhibits d33 and d31 at 30K similar or higher than that of PZT at room temperature and it has a very high electromechanical coupling. These properties result in an excellent figure of merit for resonant devices. TRS and Va. Tech. will use single crystals to fabricate "wobbling mode" and "flexural traveling wave" piezomotors with "33 mode" single ring stacks and plate stacks instead of the conventional "31" mode plates for excitation. In the Phase I project, FEA modeling considering the special properties of single crystals will be conducted and novel piezomotors with "33" mode single crystal ring and plate stacks will be built and characterized at temperatures from 300K to 80K. By the conclusion of Phase I program the feasibility of single crystal piezomotor for cryogenic rotary motion control requiring large torque and high angular resolution will be demonstrated. The optimum single crystal piezomotor design and the precise cryogenic rotary motion control system development will take place in Phase II.

POTENTIAL NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
Cryogenic actuation with large stroke, large torque, high precision, position set-hold at power-off characteristics are desired for NASA adaptive optics, deployable truss structures, antenna tuning, space robots, space sampling (drilling), and positioning. In particular, the proposed cryomotor could be used for the shape control actuators, position control actuators and force control actuators for the space telescopes and in other space exploring missions.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
Large stroke, large torque, high precision piezomotors have applications such as active vibration control and structure morphing, RF communication tuning, lens focusing in cameras and mobile phones, micro-robots, bio-medical manipulators, photonic tooling, micro/nanofabrication and nanoassembly. Cryogenic motors have applications in super conductive RF device tuning and cryogenic microscopy.
