Wearable sensor device for contacting skin of a person

Abstract

A wearable sensor assembly for contacting skin, the sensor assembly comprises a hollow, flexibly deformable protrusion, a sensor module, and a sensor device fixating structure. The protrusion is preferably a cushion- or a balloon-shaped protrusion. The protrusion comprises a base and an apex, preferably a substantially flat apex. At least part of the apex forms a contact area for contacting the skin. The sensor module is mounted on or inside the protrusion, preferably on or against the contact area. The sensor device fixating structure is configured to press the contact area with a substantially constant pressure against the skin. When the contact area is pressed against the skin, an increase, respectively decrease of a force exerted on the sensor device deforms, e.g. deflects and/or compresses, the protrusion such that the contact area that is in contact with the skin increases, respectively decreases, while the pressure stays substantially the same.
