This paper investigates how the power generated by electromagnetic based vibrational power generators scales with the dimension of the generator. The effects of scaling on the magnetic fields, the coil parameters and the electromagnetic damping are presented. An analysis is presented for both wire-wound coil technology and micro-fabricated coils.
This paper reviews kinetic energy harvesting as a potential localised power supply for wireless applications. Harvesting devices are typically implemented as resonant devices of which the power output depends upon the size of the inertial mass, the frequency and amplitude of the driving vibrations, the maximum available mass displacement and the damping.(More)
This paper introduces a voltage multiplier (VM) circuit which can step up a minimum voltage of 150 mV (peak). The operation and characteristics of this converter circuit are described. The voltage multiplier circuit is also tested with micro and macro scale electromagnetic vibrational generators and the effect of the VM on the optimum load conditions of the(More)
This work presents a novel process to fabricate nanos-tructures for thermoelectric applications by a combination of a traditional silicon microfabrication techniques, elec-troplating, and submicron ion-track nanolithography. Polyimide (Kapton HN, PI2731), and PMMA (poly-methyl methacrylate) were ion-track irradiated and wet etched. Bi 2 Te 3 nanowires (80(More)
