Abstract
An apparatus 100 for sensing a physiological parameter of a subject comprises a force sensor 102 configured to generate a first signal representing force displacement of an organ of the subject and a displacement sensor 104 associated with the force sensor 102. The displacement sensor 104 is configured to generate a second signal representing displacement velocity of the organ of the subject. A coupler 106 is arranged on one of the force sensor 102 and the displacement sensor 104, the coupler 106 being configured to mechanically couple the force sensor 102 and the displacement sensor 104 with the organ.
