MEMS Rogowski coil current sensor with spiral return coil

Electrical Engineering in Japan, 2022
AbstractWe have developed a MEMS Rogowski coil current sensor with spiral return coil. The Rogowski coil is formed on a silicon substrate clockwise and counterclockwise from the edges, for current detection and external magnetic noise compensation (device size 10 × 10 × 0.3 mm3, spiral coil 135 turns, via diameter 100 μm).

Rogowski Coil With Ferromagnetic Powder Core

IEEE Magnetics Letters, 2022
We have used nanocrystalline powder to build a core for Rogowski coils suitable for application in energy meters. The sensor linearity error is 0.32% of full scale (FS) of its 20 A range, which is acceptable for this application.
