Claim 14:
15. A measuring device, comprising:
a displacement sensor assembly configured for use in measuring a biological parameter at the skin of a user, the displacement sensor assembly including:
a contact surface facing towards an exterior of the assembly for contacting the skin of a user, the contact surface being movable along a central axis of the assembly in response to pressure change at the skin;
a sensing unit having an optical axis and comprising at least one detector and at least one light source configured to emit light along the optical axis directly towards the detector;
a light blocking member associated with the sensing unit; and
a mounting arrangement, by virtue of which the sensing unit and the blocking member are mounted within an interior of the assembly so that one of the sensing unit and the blocking member members is fixedly associated with the contact surface so as to be movable therewith, and the other one is free of such fixed association with the contact surface, the arrangement being such that movement of the member associated with the contact surface relative to the member, which is free of such association, is configured to cause the light blocking member to at least partially block light emitted by the light source towards the detector, allowing that light from the light source received by the light detector to be indicative of the displacement of the contact surface; and

at least one biological sensor configured for optically measuring at least one biological parameter of a user, the biological sensor is being fixed to the contact surface and facing the same direction as the contact surface for performing the optical measurement via the contact surface.
