L2M -Vibrational Energy Harvester With Self-Resonant Frequency Adjusting For Wireless Sensing Network

This project will support the development and validation of a novel vibration energy harvester (VEH) with resonant frequency tuning. VEHs convert mechanical vibrations into electrical energy and can be used to power wireless sensor network (WSN) nodes for machine condition monitoring in manufacturing and processing. Conventional VEHs are resonant devices with inherently narrow bandwidths, making them effective only at a specific frequency, presenting a practical challenge as vibration conditions can vary. The proposed design uses a mechanism that can passively tune its resonant frequency, enabling energy harvesting over a wider range of operating conditions. By providing a more versatile power supply for WSN nodes, this technology can reduce battery dependence, lower operating costs, and enable wider adoption of machine condition monitoring. The project will engage stakeholders to ensure market fit and will test the system under representative conditions to advance commercialization for the partner organization.
