Abstract
An energy harvester (100) includes: an inner band (110); an outer band (120) arranged to surround the inner band (110), wherein the inner band (110) is coupled to the outer band (120) at a fixed end (20) and the inner band (110) is spaced from the outer band (120) at a free end (30); and an energy generator (150) arranged to generate electric energy through relative movement between the inner band (110) and the outer band (120) at the free end (30). Also disclosed is a wearable device (10) including: a wearable strap formed by the inner band (110) and the outer band (120) of the energy harvester (100), and a mass (130) arranged to receive at least a portion of the wearable device (10).
