“Sweat and Gas Sensor for Healthy Skin and Atopic Dermatitis”
Pilot study of a wearable gas and sweat skin sensor
Device - Gas sensor
The gas sensor is an airtight gas capsule attached with a floating solid phase microextraction (SPME) tube. SPME uses a fiber coated with a nontoxic liquid (polymer), and a nontoxic solid (sorbent). The fiber coating extracts the compounds from the gas being released from the skin. Only the glass sample is in contact with the skin.
Device - Sweat Sensor
The sweat sensor is a soft, flexible device that rests on the skin and collects secreted sweat through capillary action. The device is held in place by medical-grade acrylic adhesive film.
