Cross-Channel Impedance Measurement for Monitoring Implanted Electrodes

By Kirstin Ahmed

We developed a new method to calculate the strength of electrical connections between sensors implanted in the body, such as those used with our neuromusculoskeletal prosthesis. This method relies only on simple mathematics, and can work for any type and number of implanted sensors that share an electrical reference. Using this method, we are able to paint a more complete and accurate picture of how well our implanted sensors are working, as well as to more quickly pinpoint the cause of issues when they arise.
