Energy harvesters are traditionally heavy and create burden in the energy capture process. This smart materials-based energy harvester enables wearable electronic devices. Made with a lightweight macro-fibre composite, it captures energy from motion of the human knee, deforming piezoelectric transducers to generate electricity. Walking 10,000 steps at normal speed is enough to power a smart wristband for the whole day.

Uniqueness and Competitive Advantages:

  • Light (307g only) and easy to wear/take off
  • No extra metabolic burden to users
  • Can power wearables especially for hikers, e.g. pedometers, health monitors, GPS
  • Can be embedded into garments for sportswear
Placement of the energy harvester on a leg
Layout and components of the developed energy harvester
