By Duncan Graham-Rowe LIFE-saving medical implants like pacemakers and defibrillators face a big drawback: their batteries eventually run out. So every few years, patients need surgery to have the batteries replaced. Now a company in New York state is planning to tackle the problem by providing patients with an implantable power source that recharges their implant’s batteries using electricity generated by the patient’s own body heat. By continuously recharging the batteries, it saves the patient from frequent surgery. In some low power devices, it could even replace the batteries altogether, making such operations unnecessary. The “biothermal battery” under development by Biophan Technologies of West Henrietta,
