Revolutionary electrical current sensors harvest wasted electromagnetic energy

The chip can be placed on any sensing point of interest such as electrical cables, conductors, junctions, bus bars, etc. to detect electrical currents. What's more, it does not necessitate the use of additional power supplies and signal conditioners which are generally required by traditional current sensors such as Hall sensors, reluctance coils, etc.
