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; and
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 a physical part of the light source element, or a geometric projection of said physical part of the light source element on a detector plane defined by the detector element, borders with a part of said at least one detector element, such that a boundary of the physical part of the light source element, or the geometric projection of said physical part of the light source element on said detector plane is adjacent, and thereby having no effective gap, to a boundary of the part of said at least one detector element.
