Non-Contact Wearable Device:
A new non-contact wearable developed by researchers from the U.S. and South Korea can monitor health by measuring skin flux without direct contact.A small, smartphone-sized wearable device that tracks molecular flux through skin—measuring outward vapour and inward chemical entry—without touching the skin. Developed by a team led by Prof. John A. Rogers at Northwestern University, USA. Contains a sealed chamber adjacent to the skin, forming a microclimate. Equipped with wireless electronics and miniature sensors to measure: Water vapour, Carbon dioxide (CO₂), and Volatile organic compounds (VOCs). A remote-controlled valve regulates the chamber’s openness, allowing comparative flux measurements between closed and open states.
