Although microsystems today require less power than ever before, they still cannot fit large enough batteries to sustain them for months or years at a time. Ambient energy is appealing, but only when available, which is often not the case for embedded sensors. Transmitting power wirelessly is more practical in these applications. Tiny receivers, however, capture a small fraction of the power that...
Although energy in vibrations is often vast, the electrostatic force with which tiny variable capacitors draw power from motion is miniscule, so output power is low. Thankfully, extracting energy at higher voltages generates more power because the electrical damping force that impedes motion to draw power is stronger. Clamping the transducer to a battery is convenient in this respect, but limiting...
