Abstract Details

2019, Master of Science in Engineering, University of Akron, Mechanical Engineering.
The proliferation of MEMS devices, especially their use in remote and harsh environments, has prompted the need for novel methods of supplying power. Energy harvesting is one such attractive approach, converting energy from the device’s environment into usable power and eliminating the need for external batteries. There are boundless sources of thermal energy (vehicle exhaust, industrial chemical reactions, etc.) from which to harvest. However, energy harvesting systems, especially within thermal applications, exhibit inherent limitations which must be overcome. In this work, a thermally-actuated energy harvester utilizing a combination of shape memory alloys and mechanical frequency up-conversion is designed. The equations of motion for the system are presented, including physically accurate models of a bistable mechanism and shape memory alloy constitutive behavior. Finally, the system is studied in various configurations through exhaustive numerical simulation to characterize system performance and optimize energy harvesting efficiency.
