摘要：
A sensing structure for a physiological signal, a stethoscope therewith and a manufacturing method therefor are introduced herein. The sensing structure for physiological signals includes a flexible substrate, a piezoelectric sensing structure and a damping structure. The piezoelectric sensing structure, disposed over the flexible substrate, has two opposite surfaces including a first surface and a second surface. The second surface of the piezoelectric sensing structure faces the flexible substrate. The piezoelectric sensing structure is an arc with a certain curvature, in which the first surface thereof faces outward. The damping structure is disposed inside a room exists between the flexible substrate and the piezoelectric sensing structure. In one embodiment , a further structure for amplifying the sensing result is disposed over the first surface of the piezoelectric sensing structure and can or cannot contact a top region of the first surface.本揭露內容提出一種生理訊號感測結構及包括所述生理訊號感測結構的聽診器及其製造方法。此生理訊號感測結構包括一軟性基板、一壓電感應層以及一阻尼結構。所述壓電感應層配置於軟性基板上,其中壓電感應層包括一第一側面與一第二側面,其中第二側面面向軟性基板,而壓電感應層以一曲率弧度彎曲,而以第一側面向外。所述阻尼結構配置於軟性基板與壓電感應層之間。在一例子中,更包括一放大震幅結構,配置於壓電感應層在第一側面的曲面區域上,與曲面區域弧度的一頂部區域接觸或不接觸。100‧‧‧生理訊號感測器110‧‧‧軟性基板120‧‧‧壓電感應層122‧‧‧邊緣區域124‧‧‧曲面區域126‧‧‧頂部導電層127‧‧‧底部導電層128‧‧‧壓電材料層130‧‧‧阻尼結構140‧‧‧胸腔
