Variable-capacitance power generation

  1. Jan 18, 2012 #1
    A few days ago I read the phrase "variable-capacitance power generation." I tried to find more information, but nothing turned up. Is anyone here familiar with it?

    How about here. The basic idea is to scavenge small amounts of vibrational energy by causing it to wiggle a capacitor.
