(NEWELECTRONICS) — Researchers at the University of Cambridge have developed a transistor which operates on energy ‘scavenged’ from its environment and say this could enable devices which function for months or years without a battery.
Using a principle to that of a computer in sleep mode, the transistor harnesses leakage current for its operation – the first time this has been captured and used functionally. The transistors can be produced at low temperatures and printed on materials ranging from glass and plastic to polyester and paper.
The transistor is based on a geometry which uses a characteristic previously thought to be ‘non desirable’ – the point of contact between the metal and semiconducting components of a transistor, or Schottky barrier.
