Researchers at UC San Diego have developed a temperature sensor that runs on tiny amounts of power \u2014 just 113 picowatts, around 10 billion times less power than a watt. The sensor was described in a study recently published in Scientific Reports<\/a><\/em>. \u201cWe\u2019re building systems that have such low power requirements that they could potentially run for years on just a tiny battery,\u201d Hui Wang, an author of the study, said in a statement<\/a>.<\/p>\n

The team created the device by reducing power in two areas. The first was the current source. To do that, they made use of a phenomenon that many researchers in their field are actually trying to get rid of. Transistors<\/a> often have a gate with which they can stop the flow of electrons in a circuit, but transistors keep getting tinier and tinier. The smaller they get<\/a>, the thinner the gate material<\/a> becomes and electrons start to leak through it \u2014 a problem called \u201cgate leakage.\u201d Here, the leaked electrons are what\u2019s powering the sensor. \u201cMany researchers are trying to get rid of leakage current, but we are exploiting it to build an ultra-low power current source,\u201d said Hui.<\/p>\n

The researchers also reduced power in the way the sensor converts temperature to a digital readout. The result is a temperature sensor<\/a> that uses 628 times less power than the current state-of-the-art sensors.<\/p>\n
