Summary
Researchers at North Carolina State University have developed a wearable patch that detects environmental hazards and alerts the wearer through distinct vibration patterns. This device aims to provide immediate warnings for dangers like hazardous gases or contaminated water, bypassing the need for phone notifications. The patch uses six sensors, a microcontroller, a battery, and thin-film photovoltaic cells for solar charging, and was successfully tested in proof-of-concept trials.
