A Micro Kinetic Energy Harvester Demonstrating Energy Harvesting From 3-D Mechanical Motion and Power Increasing Through Magnetic-Based Frequency Rectification Available to Purchase

In this paper, we report a micro 3-D kinetic energy harvester demonstrating an energy conversion from environmental mechanical-energy (3-D mechanical motion) to electrical energy (voltage output). In addition to energy harvesting/conversion from 3-D motion, we demonstrate a non-contact frequency-up rectification approach which converts an incoming lower vibration frequency to a higher frequency in order to increase the power output of the harvester.
