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).

Linear Rogowski coil

Review of Scientific Instruments, 2017
Nowadays, the employment and development of fast current pulses require sophisticated systems to perform measurements. Rogowski coils are used to diagnose cylindrical shaped beams; therefore, they are designed and built with a toroidal structure. Recently, to perform experiments of radiofrequency biophysical stresses, flat transmission lines have been ...
