Claim 0:
1. A system for determining a biological parameter of a subject, the system comprising:
(i) a displacement sensor comprising:
a contact surface configured to contact skin surface of the subject;
a sensing unit having at least one light detector and at least one light source with an optical axis defined between them, the light source being configured to emit light directly toward the sensor which is configured to detect the light; and
a light blocking member associated with the sensing unit, such that displacement of the contact surface induces the blocking member to block light propagating along said axis in a manner proportional to the displacement of the contact surface, in response to pressure change of the skin on the contact surface, to obtain data indicative of displacement of the contact surface;

(ii) a control unit in data communication with the displacement sensor for receiving data indicative of said movement of the contact surface; said control unit comprises extractor module for extracting the biological parameter from the data indicative of movement of a skin surface; and
(iii) an optical biological sensor having a common contact surface with the displacement sensor.
