Embedded optimization can be used to enhance numerous applications and create new opportunities. In this talk, the concept of a current sensor that detects the position of the current-carrying conductor is introduced. The additional information is gathered using model-based nonlinear optimization and multiple magnetic field sensors. A proof-of-principle device is built and experimentally evaluated. 

The talk is based on a master thesis in Microsystems Engineering conducted at the University of Freiburg together with TDK Micronas. This thesis was awarded the Best Thesis Prize of FAIM - Forum angewandte Informatik und Mikrosystemtechnik  - on January 30, 2019, by FAIM president Jürgen Wieland, who is also the CEO of Embex GmbH in Freiburg.
