Scientists develop wearable gas sensor to monitor health

▴ wearable gas sensor to monitor health
It is an improvement over existing gas sensor as it enhances sensitivity.

Scientists from Pennsylvania State University have developed a highly sensitive, wearable gas sensor which will help monitor environment pollutants and detect biomarkers for medical condition.

The device is expected to be soon commercially available, is an improvement over the existing wearable gas sensor. The new wearable gas sensor uses self-heating mechanism that enhances sensitivity. This allows for quick recovery and reuse, unlike other devices which require external heating.

Nano materials are generally being used by people because of their larger surface-to-volume ratio makes them highly sensitive. The problem with nanomaterial is that it cannot be easily hooked up to with wires to receive signals, necessitating the need for inter-digitated electrodes, which are like the digits in your hand.
