Zero Power always awake signal monitor

A signal powered device with a wide input voltage range.

Many electronic devices have long sleep cycles, but are constantly listening for a signal. Such devices may be low power devices relying on energy harvesting from solar or kinematic energy generation or may receive their power through wireless transmission. This listening process requires power which may come from stored energy devices such as batteries or capacitors and which has to be replenished when the generating source is intermittently available.

Alternatively, there are many mains electricity powered standby circuits (i.e. TVs) where there is a need to reduce the power consumed in the listening mode to a minimum.

This patented device (UK Application 1607304.1 pending) can be used to listen for small signals from a variety of sources with no external power supply and then enable further activation, storage or other circuits.
