Planar Microfluxgates Using Electroplated NiFe Cores Aimed for the Monitoring of Cardiac Valves Prosthesis

Abstract

Fluxgates are high sensitivity magnetometers. This work presents our efforts to produce microfluxgates using electrodeposited NiFe cores. Large form-factor parameters were adopted, but with all the miniaturization benefits like low price, low power consumption, usability in embedded systems, etc. We also focus on a specific application that is the monitoring of cardiac valves prosthesis.
