NAVY SBIR award for energy harvester development using single crystal PMN material TSI teamed with the Department of Aerospace Engineering at the University of Maryland and TRS Technologies, Inc. was selected for a Phase I SBIR award on 27 March 2007 from the Office of Naval Research SBIR program to develop an innovative energy harvesting technology by exploiting the high-performance single crystal PMN material. Project leader, Dr. Gang Wang and his colleagues are working to develop and demonstrate energy harvester devices to power electronics used as components of an Integrated Condition Assessment System (ICAS) in the naval application. The vibration based energy harvester (VBEH) will be mounted to a substructure and use ambient vibrations for energy generation. Single crystal PMN materials will be used in the energy harvester to convert mechanical deformation into electrical energy and interface with a battery element via appropriate circuitry with the ultimate aim to power electronic devices. The energy harvester can be tuned to expected vibration spectrum of the substructure and small vibrations can be amplified by resonance tuning to achieve large energy extraction capabilities. To the best of our knowledge, this research is the first attempt towards developing a vibration based energy harvester by exploiting superior performance characteristics of new single crystal ferroelectric material, PMN. Our goal is to provide sufficient energy to power naval sensor and small electronic systems. The VBEH technology will be applicable to a wide range of end-users in the defense, commercial, and industry sectors. Download a spec sheet for the TSI Energy Harvester |
