Device, system and method for measurement of a skin parameter

Abstract

The present invention relates to a device for skin parameter measurement, comprising a housing structure (112) defining an interior cavity (120) and a first opening (122) at a skin contact end (124) of the interior cavity (120), a movable part (113, 117) connected to the housing structure (112) via an elastic connecting arrangement (126), the movable part (113, 117) being movable with respect to the housing structure (112) and configured to protrude the skin contact end (124) through the first opening (122) of the housing structure when no external force is applied to move the movable part (113, 117) with respect to the housing structure, the movable part (113, 117) further comprising a second opening (116), an optical sensing unit (118) for performing measurement of a first skin parameter when the device is in contact with a skin surface, the optical sensing unit being provided within the interior cavity of the housing structure and comprising an illuminating unit (118A) for illuminating the skin surface by emitting light through the second opening (116) of the movable part and an imaging unit (118B) for receiving light reflected by the illuminated skin surface, and an electrical sensing unit(136) for measuring a second skin parameter, wherein the electrical sensing unit (136) is arranged at a front end section of the movable part (113, 117) defining the second opening (116).
