A sensor system for the combined, simultaneous, common-axis collection of heart-produced acoustical and electrical signals. The system includes (a) a hollow-interior body of revolution possessing an axis of revolution which is substantially coincident with the common signal-collection axis, (b) an electrode structure mounted on the outside of the body and disposed symmetrically with respect to the signal-collection axis, (c) a sound transducer disposed within the interior of the body, substantially centered on the signal-collection axis, (d) a cushion of revolution circumsurrounding and supporting the transducer within the body in a manner which substantially isolates the sound transducer from spurious noise events, and (e) an anatomy-adhereable acoustic membrane, disposed in the path for sound collection to act as a mechanical anatomy-to sensor impedance-matching coupler assisting in sound-signal collection. |
