摘要

An energy harvesting bracelet (EHB) based on two mutually exclusive circular motion permanent magnetic movers is demonstrated, which is able to capture energy through the natural motions of the wearer's wrist. The EHB can transform the translational motion in any orientation except the axial into the rotational motion of the movers, which passes through four coil transducers and induces significantly large electro-motive forces across the coils. A prototype EHB is shown to produce power that can charge a capacitor with 470 μF 25 V up to more than 0.81 V during at most 132 ms from any single excitations.
