While previous attempts to incorporate health sensors in earbuds faced challenges like comfort, battery drain, and a lack of compelling use cases, there are ongoing developments to overcome these issues. One company, MindMics, has developed technology that allows users to monitor heart rate and other health characteristics acoustically, using the ear canal as a microphone. Dr. Anna Barnacka, the founder and CEO of MindMics, explains that their technology utilizes sound waves generated by the body to provide insights into health, making it a non-invasive and promising method for health monitoring.
