A new, sensitive, wearable gas sensor made up of nanocomposites has been developed and may be commercially available in the near future. The sensor can be used to detect and monitor conditions in the environment and in the body. A research group from Penn State University (PSU; PA, USA) and Northeastern University (NU; MA, USA) have improved upon a design for a gas sensor. The new design includes a self-heating mechanism as opposed to the original external heater, therefore, is more efficient as it allows for a lower functioning temperature enabling quick recovery and reuse of the device.
