The custom boost converter works for input voltages of as little as 20 millivolts and produces an output voltage of 1.1 volts, enough to run low-power sensors.

For the first time researchers have run an electrical circuit entirely off power in trees. The findings suggest a new power source for wireless sensors -- and a way to monitor tree health.

Led by Assistant Professor Kou Li, a research group in Chuo University, Japan, has developed chemically enriched photo-thermoelectric (PTE) imagers using semiconducting carbon nanotube (CNT) films, ...

They inserted an aluminum-nitride insulating layer into a conventional energy-harvesting chip based on ZnO and found that the added layer increased the output voltage a whopping 140 to 200 times (from ...

Test & Measurement World now has a LinkedIn group. Yesterday, John Kirk, Research Engineer at Raymond Corporation posted the following question. Here’s my problem: measuring voltage accurately. That ...

In fact, researchers at the Massachusetts Institute of Technology found that plants can pack up to 200 millivolts of electrical power. A millivolt is one-thousandth of a volt.
