University of Bristol Announces UB20M, Voltage Detector IC to Eliminate Standby Power
Ultra-low power consumption: 5.4 pA at 1 V and 20°C
Low threshold voltage: 650 mV
High input voltage capability: up to 20 V
Low off-state output leakage: below 100 pA
The new UB20M voltage detector IC in Fig. 1 enables zero-power sensing and listening. It allows circuit designers to eliminate standby power, to develop circuits that perform continuous monitoring without using battery power, and to implement wireless wake-up with zero receive power. The device is a sensor-driven circuit that requires no power supply, instead it uses a fraction of the power contained in the output signal of the sensor.
Here’s a demonstration video up front with some demos in the wild afterwards, along with a teardown at the end:
