At the University of Cambridge, a group of engineers devolved a transistor that is said to be able to function for years without a battery. All transistors currently have a small leakage of electrical current. A way to think of it is as a leaky faucet. For the first time, this group of engineers has been able to capture the leakage and use it to the transistors advantage. The transistors are able to be produced at low temperatures and on almost any material. This new transistor uses what was once thought to be an undesirable characteristic, contact between the metal and the conduction components. This was discovered to be ideal for the ultra power saving applications the school has been looking at. An example of this would be health monitoring. This new design will take away the problem of not being able to produce the transistors at smaller sizes. The new transistors, power consumption is less than a billionth of a watt. To put that in perspective, if that was to be drawn directly from an AA battery, it would last for billions of years. The engineers are convinced that this will become the new design for all ultra power devices.
