Applications which require the precise monitoring or regulation of dissipated load power, such as motors or servos, can make use of a circuit that measures real power by finding the product of the ...

A voltage multiplier is applied as a high source impedance, 36V, 300mA, 12W LED driver. The high source impedance is ideal for driving power LEDs because it accommodates variations in LED junction ...

A bump circuit with flexible tuning ability that uses 500 times less power and is smaller than previous circuits has been demonstrated by researchers at the University of Tennessee in the US.

Researchers have developed an electric circuit that runs on the power generated by trees. The researchers say it should be enough to power wireless sensors and could also gauge a tree’s health.
