Infinite Power Solutions has developed a thin film solar cell that can recharge itself about 75,000 times, possibly the life of the device. Current ones can only be recharged between 300 - 1,000 times and a previous model of IPS was capable of 10,000 turns. These Thinergy batteries are 0.17 mm thick and can be implanted into RFID cards, remote sensors, Bluetooth devices and quartz watches. Don't expect to see them en mass any time soon as it may be a while before the cost becomes affordable.
