Ultralow power transistors could function for years without a battery

A newly-developed form of transistor opens up a range of new electronic applications including wearable or implantable devices by drastically reducing the amount of power used. Devices based on this type of ultralow power transistor could function for months or even years without a battery by 'scavenging' energy from their environment.
