Bioelectronic sensors to monitor skin health
Research & Innovation


In this world of Big Data, the skin has also a message to send.

Why skin would need to communicate? What kind of information data it provides?

To give us feedback about the thermal condition it lives in. And for two more reasons: because it could be connected and correlated to other data (thickness of stratum corneum and thermal transport properties), and therefore to concrete information and comprehensive analysis of the effectiveness of active compounds.

Together with University of Illinois at Urbana-Champaign and Tampere University of Technology, L’Oréal researchers published an open access paper in PLOS ONE: “Thermal Transport Characteristics of Human Skin Measured in Vivo Using Ultrahin Conformal Arrays of Thermal Sensors and Actuators”.

This publication reveals how devices will be used in cosmetology and dermatology, for thermal evaluations in a non-invasive manner.

The feasibility is illustrated by measurement of clear relationships between skin hydration and in vivo thermal properties shown across six body locations (cheek, dorsal and volar forearm, wrist, palm and heel pad) on twenty-five subjects.
