Abstract: A sensor for sensing bioacoustic energy includes a housing comprising an interfacing portion configured to establish coupling with a body part during use of the sensor. An anchoring arrangement is defined on the housing. A transducer member has an anchoring end and at least one free end. The anchoring end of the transducer is coupled to the housing such that the transducer member is arranged to be preferentially sensitive to bioacoustic energy transferred to the transducer via the interfacing portion relative to other portions of the housing.

Abstract: A sensor for sensing bioacoustic energy includes a housing comprising an interfacing portion configured to establish coupling with a body part during use. The sensor includes a transducer element coupled to the interfacing portion of the housing and configured to sense sounds produced by matter of biological origin. One or more conductors are coupled to the transducer element. A mass element is compliantly coupled to a surface of the transducer element. Intervening material is disposed between the transducer element surface and the mass element, and allows for differential motion between the transducer element surface and the mass element during excitation of the transducer element.
