Novel energy harvester

Ref No: Ses-2673-11

In recent years, there has been an increasing interest in vibration energy harvesting, especially to enable self-powered wireless sensor networks for structural health monitoring. While some early commercial solutions have witnessed increasing deployments, two of the key technical limitations still stubbornly persist; namely, the low power density relative to conventional power supplies and the mismatch between the narrow operational frequency bandwidth of conventional energy harvesters and the wideband nature of real vibrations. Researchers at the University are addressing these issues through employing vibration energy harvesting based on auto parametric resonance rather than the conventional approach of using the fundamental mode of resonance to produce a novel energy harvester.
