NASA Langley’s Hybrid Actuators System – Available to License


Laboratory: NASA Langley Research Center

Technology: Hybrid actuator system (HYBAS)

Opportunity: This NASA technology is available for licensing to interested parties.

Details: NASA's Langley Research Center has developed actuators and transducers that are deployed to harvest mechanical energy in the environment and store it as electrical energy, and to convert stored electrical energy into mechanical energy. By developing a transducer based on advanced electroactive materials, NASA has produced a design that can harvest orders of magnitude more energy in a given application than traditional solutions, yielding more power to drive devices and to store in batteries. In a complementary effort, a hybrid actuator system (HYBAS) with both an electroactive polymer (EAP) and an electroactive ceramic (EAC) achieves enhanced displacement performance from a single power supply, greatly reducing electrical consumption while simultaneously improving mechanical displacement compared to current state-of-the-art actuators.
