Pilot study of a wearable gas and sweat skin sensor
The objective of this study is exploratory and deploys two wearable sweat and gas sensors which detect the composition of sweat proteins and volatile gases emitted from the skin in healthy subjects and patients with atopic dermatitis.

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.
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.
