Abstract

A power-generating device is disclosed that includes a pyroelectric material having first and second surfaces on opposite sides of the pyroelectric material. The device also includes a first conductive electrode coupled to a first support element that is configured to intermittently bring the first electrode into proximity with the first surface and a second conductive electrode proximate to the second surface at least while the first electrode is proximate to the first surface. The device also includes a power module that is electrically coupled between the first and second electrodes. The power module is configured to capture power from an electrical current flowing between the first and second electrodes.
