Title:
PRESSURE SENSOR DEVICE
Document Type and Number:
Japanese Patent JP2018194529
Kind Code:
A
Abstract:
To provide a pressure sensor device that can clarify the difference in the state of a current between when a pressure sensing body is not subjected to pressure and when is subjected to pressure.SOLUTION: The pressure sensor device includes: a sensor substrate having a substrate and a plurality of sensors on the substrate, the sensors arranging in a first direction and a second direction intersecting with each other and including a first electrode; a pressure sensing part having a pressure sensing body facing the sensor part and a plurality of protrusions located on the opposite side of the sensor substrate with respect to the pressure sensing body; and a plurality of supporting parts between the sensor substrate and the pressure sensing part. The plurality of protrusions do not overlap with the supporting parts at the top of the protrusions when viewed along the normal direction of the substrate.SELECTED DRAWING: Figure 2
