Wearable Electronics

Wearable electronics that measure the electrical activity of the human body in a continuous, non-invasive fashion are receiving a great deal of attention for healthcare and fitness monitoring applications. Establishing a reliable electrical contact with skin is a challenging problem: Current electrodes show a limited lifetime and are uncomfortable to wear. We develop electronically conducting ionic liquid gels that enable long-term cutaneous recordings. These biocompatible gels are designed to adhere to skin and make low impedance contacts that are comfortable to wear.
