A variable-capacitance-type electrostatic migrogenrator harnessed motion of the living body was proposed and examined its performance. Three honeycomb-types variable capacitance that were the dominant part of electrostatic generator were made. Capacitance of type A model changed from 3.0 to 9.3 nF. That of type B model changed from 3.5 to 10.8 nF. That of type C model changed from 75 to 240 nF. There was big difference in layering method of the electrodes between type A model and type B or type C model. Output energy could not measure in type A model. Type B model generated B μJ in one cycle. Type C model generated 70 μJ in one cycle when initial supply voltage was 6 V. This means that type C microgenerator can supply enough power to operate a cardiac pacemaker if it can be vibrate over 1 Hz.
