- An alcoholic drink will give you a buzz, but if someone laced it with something dangerous, a new poison-snooping patch will buzz your skin to warn you.
- Containing its own battery, sensors for six environmental hazards, a microcontroller, and an actuator that provides vibration, the patch exists inside its own “skin” of photovoltaic cells, leveraging its location on the skin to recharge from sunlight.
- For Lilian Hsiao, co-corresponding author and NCSU associate professor of chemical and biomolecular engineering, her team’s breakthrough is more than welcome.
