Title:
BIOLOGICAL VIBRATION SIGNAL DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/163740
Kind Code:
A1
Abstract:
[Problem] To provide a biological vibration signal detection device comprising a more reliable connection part. [Solution] The detection device comprises: a sheet-like vibration sensor body comprising a sensor material layer containing a piezoelectric material, a first electrode layer formed on the upper surface of the sensor material layer, and a second electrode layer formed on the undersurface of the sensor material layer; an outer protective layer covering the entirety of the vibration sensor body; a first output electrode that is disposed in a connection part of the vibration sensor body and is connected to the first electrode layer; and a second output electrode that is disposed in the connection part of the vibration sensor body and is connected to the second electrode layer. One end of the first output electrode is connected to the surface of the first electrode layer without penetrating the first electrode layer, and another end of the first output electrode is disposed outside the outer protective layer. One end of the second output electrode is connected to the surface of the second electrode layer without penetrating the second electrode layer, and another end of the first output electrode is disposed outside the outer protective layer.
