Reliable Structures and Wearable Systems Call for Multiphysics Simulation The goal is to understand multiphysics interactions at every stage of the development process of a range of microelectronic devices: from sensors of concrete health to wearable bio-impedance meters. Used the AC/DC modeling capabilities of COMSOL to create a simulation in the frequency domain to assess the impact of electrode shape and position on the accuracy of measured physiological parameters.
