Abstract
An energy harvester is provided for harvesting energy, and in particular electrical energy from an input vibration such as an ambient vibration. The energy harvester comprises a first mechanical amplifier responsive to the input vibration and a second mechanical amplifier coupled to the first mechanical amplifier. At least one of the first and second mechanical amplifiers comprises a parametric resonator, and a power output of the energy harvester is generated by damping the second mechanical amplifier.
