General model with experimental validation of electrical resonant frequency tuning of electromagnetic vibration energy harvesters
Significance of output:
This industrial collaboration reports, for the first time, a general theoretical model in the vibrant field of electromagnetic vibration energy harvesting; it was validated on a macro-scale product from Perpetuum and a prototype micro-scale tuneable harvester. The approach allows other researchers to overcome the existing constraint of matching the harvester’s resonant frequency to that of the vibration, facilitating optimised designs. The technology was applied to Perpetuum Ltd’s products, where it gives an improvement of a factor of 4 in bandwidth. The work led to the TSB project: Energyman (~£100k). 223 article downloads since September 2012 (6 months)
