Energy Harvesting and Smart Wearable Technologies

​

 Energy Harvesting

The group developed a hybrid generator by combining two energy conversion concepts, piezoelectric and triboelectric effects, after successfully unravelling the transduction mechanisms of the individual generators and the combined effects. 

It is a sandwich structure, whose surface has zinc oxide nanorods to maximise the effective electrification area. The energy output can be increased by 50 to 60% owing to the nanorods.
