Wearable Sensors Detect Gas Leaks

Gas accidents — such as toxic gas leakage in factories, carbon monoxide leakage of boilers, or toxic gas suffocation during manhole cleaning — continue to claim lives and cause injuries. Developing a sensor that can quickly detect toxic gases or biochemicals is still an important issue in public health, environmental monitoring, and military sectors. A research team has developed an inexpensive, ultra-compact, wearable hologram sensor that immediately notifies the user of volatile gas detection.
