    • A device for sensing lung sounds, comprising: a piezoelectric sensor comprising an electrical conductive plate attached to a piezoelectric material, said sensor encased in a body structure; a first electric wire connected to the piezoelectric material on the opposite side of said plate; a second electric wire connected to said plate; a connector connected to the other ends of said first and second electric wires; and an adhesive layer connected to the surface of said plate on the side opposite to the piezoelectric material, said adhesive layer facing away from said plate; said device adapted to provide electrical signals representing vibrations present on the surface of a object when it is attached to said object surface with said adhesive layer; said electrical signals resulting from vibrations on the object surface, wherein stress applied on the piezoelectric material generates electrical voltage-difference on both sides of the piezoelectric material, creating voltage build-up on said first and second electric wires.
    • 一种用于感测肺声的装置,包括:压电传感器,包括附接到压电材料的导电板,所述传感器封装在主体结构中; 在所述板的相对侧与所述压电材料连接的第一电线; 连接到所述板的第二电线; 连接到所述第一和第二电线的另一端的连接器; 以及粘合剂层,其与所述板的与所述压电材料相对的一侧的表面连接,所述粘合剂层背离所述板; 所述装置适于提供电信号,该信号表示当物体表面上随着所述粘合剂层附着到所述物体表面时存在于物体表面上的振动; 所述由物体表面上的振动引起的电信号,其中施加在压电材料上的应力在压电材料的两侧产生电压差,在所述第一和第二电线上产生电压累积。
