WiTricity Uses Simulation to Enhance Flexible Wireless Charging

Andre Kurs, WiTricity, MA, USA

Engineers at WiTricity have developed a flexible wireless charging setup that relies on magnetic resonance and can be used for a range of applications, including medical implants, electric vehicles, and consumer electronics. Using COMSOL Multiphysics® software, the team analyzed the electromagnetic and thermal behavior of their coil configuration as a function of power drawn by the charged devices, coil displacements, and the presence of objects between the power source and receiver. From their results, they were able to optimize and validate their designs, confirm the system’s compliance to safety guidelines, and scale the setup for many different applications.
