Skin Hydration Sensor (SHS)


Recommended Posts

  • Root Admin


A significant number of rosaceans complain of dry skin. A reusable wireless device is available to dermatologists, called a skin hydration sensor (SHS), which is "a soft, battery-free, noninvasive, reusable skin hydration sensor (SHS) adherable to most of the body surface. The platform measures volumetric water content (up to ~1 mm in depth) and wirelessly transmits data to any near-field communication–compatible smartphone. The SHS is readily manufacturable, comprises unique powering and encapsulation strategies, and achieves high measurement precision (±5% volumetric water content) and resolution (±0.015°C skin surface temperature)."

The article discussing this device does mention rosacea once here: 

"Key results include clinical use of the SHS on n = 13 patients with a wide range of inflammatory skin conditions (e.g., AD, psoriasis, urticaria, xerosis cutis, and rosacea), with benchmarks against standard tools to quantitatively characterize the diseased locations."

Whether this device can be used to assist dermatologists with rosacea remains to be seen.
