Wireless Charging of Medical Devices

Engineers who work with AltaSim Technologies bring their products to market more rapidly, at a lower cost, and with an optimized design by leveraging our guidance for implementing multiphysics simulations. To help see our impact on our clients, we have put together a brief case study of a recent project using a unique solution from our simulation experts.

Problem:

One of AltaSim’s clients was developing a new wireless implantable medical device that needed to be recharged wirelessly through the skin. Our client’s engineers were concerned about meeting FDA requirements for tissue heating during recharging. Before building and testing prototypes, they wanted to determine the temperature rise of tissue surrounding the implanted device and develop simulation data that could be used in their FDA submission.

Solution:

Using our experience simulating previous wireless charging systems for implantable medical devices, our team developed a simulation of our client’s wireless charging system, including the surrounding tissue. AltaSim calculated the tissue temperature as a function of current induced in the receiving coil. The data was developed and documented to support our client’s FDA submission.

Results:

AltaSim demonstrated that the operating conditions of the wireless charging system design met FDA requirements for limiting tissue heating during charging. Our client confidently developed their prototype, demonstrated the predicted tissue temperature increase, and developed their FDA submission using the experimental and simulation data.

AltaSim partners with companies to provide simulations that increases knowledge and understanding for engineering staff of our clients. Through these simulations, we work with our clients to develop actionable plans to solve their engineering challenges. To better understand our simulation services, visit our website for an overview.
