Devices that make use of this ultralow power transistor could function for months, maybe years, without batteries, according to the team.
The transistor “scavenges” energy from its environment in a manner similar to a computer in “sleep” mode. It can harness the tiny leak of electrical current, also called a near-off-state current. Researchers suggest that such a transistor could be used in wearable or implantable devices connected to the Internet of Things.
The transistor’s operating voltage is less than a volt and its power consumption is below a billionth of a watt, according to researchers.
