The university wanted us to explore the possibility of adopting a non-invasive approach that involves placing electrodes on the surface of the skin and muscles and measuring electrical activity within.

Our scope of work involved the design of the electronics hardware and firmware and build prototypes. It also involved working together with the research team on development of a mobile app to configure and control the device. We developed a wearable device having suitable electronic circuitry that accurately measures bioelectrical activity.

One major challenge in this project was the difficulty involved in sensing the faint electrical signals generated by the contractions. We had to use special sensors that could faithfully amplify the faint signals without introducing any noise. Another challenge was the electrical signals generated by the organ under test get mixed up with signals generated by other organs in the body. We worked with the researchers at the University to help them separate out the activity of the organ under test from those of other organs. We also had the additional challenge of adhering to strict quality standards for design and documentation required for a medical electronics product.
