Detecting Environmental Hazards with a Wearable Patch

Detecting Environmental Hazards with a Wearable Patch Researchers at North Carolina State University have created a wearable patch that can detect hazardous gaseous, aerosolized, and aqueous environmental toxins and notify wearers by vibrating against their skin. For this work, the researchers created a square patch slightly smaller than a driver’s license.

The patch contains a microcontroller that serves as the patch’s brain; […].
