Abstract
An acoustic sensor is configured to provide accurate and robust measurement of bodily sounds under a variety of conditions, such as in noisy environments or in situations in which stress, strain, or movement may be imparted onto a sensor with respect to a patient. Embodiments of the sensor provide a conformable electrical shielding, as well as improved acoustic and mechanical coupling between the sensor and the measurement site.

2. An acoustic sensor assembly comprising:
-
a sensor sub-assembly comprising; a frame, a sensing element comprising a piezoelectric material that is stretched in tension on the frame and configured to generate a signal responsive to acoustic vibrations, and an acoustic coupler that is positioned to apply pressure to the sensing element; and a patient attachment portion comprising; an elastic portion; and an attachment layer comprising a first side including an adhesive surface and a second side opposite the first side, wherein; the attachment layer extends between an inner periphery of the attachment layer proximate the sensor sub-assembly and an outer periphery of the attachment layer distal the sensor sub-assembly, the elastic portion attaches to the sensor sub-assembly and extends to the second side of the attachment layer, the elastic portion is attached to the attachment layer on the second side of the attachment layer and at a point between the inner periphery and the outer periphery of the attachment layer, and the patient attachment portion is configured to enable attachment of the acoustic sensor assembly to the medical patient via user attachment of the adhesive surface to the tissue site of the medical patient. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
