we have succeeded developing human body heat power generator (Thermoelectric generator) for hearing aid in our lab, so far it is costly and not yet can be a commercial product, but we have developed and can offer the other low cost portable pocket size power generator devices, consumers can generate the power by light exercise for their own hearing aid. the more power generated the more healthy user can be.
