1. A device for sensing at least one biological parameter of a subject, the device comprising:
a contact surface configured for being brought into a contact with a skin surface of the subject;
at least one light source element for illuminating the skin surface through the contact surface along an illumination source optical axis with illumination including at least a first wavelength;
at least one detector element that comprises a detector sensing surface, wherein the detector is configured for detecting a response of said illumination on the detector sensing surface from the skin surface through the contact surface along a detector optical axis, and providing signals indicative of said biological parameter based thereon;
wherein the light source element is disposed on said at least one detector element or disposed such that the geometric projection of the light source element on the plane defined by the detector element is entirely and continuously surrounded by said detector sensing surface of the detector element.
