Parametric Resonance Demonstration

Yu Jia, final-year PhD student at the Centre for Smart Infrastructure and Construction (CSIC) has received the prestigious "best student oral presentation award" at The 13th International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS), held at The Royal Society in London.

The PowerMEMS conference is the highest tier annual, academic, international conference for the field of energy harvesting. This year's objective was to catalyze innovation in miniature, micro- and nano-scale technologies for power generation and energy conversion.

Yu Jia's presentation - titled "A Multi-frequency Operation of a MEMS vibration energy harvester by accessing five orders of parametric resonance" - demonstrated the utilisation of multiple orders of parametric resonance for vibration energy harvesting in a MEMS device to harness a significantly larger amount of the available power spectrum compared to the conventional direct resonant approach.
