PRESSURE SENSITIVE ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a pressure sensitive element having relatively high linearity characteristics in spite of a simple structure.SOLUTION: A pressure sensitive element comprises: a first electrode including at least one protrusion portion having elasticity; a second electrode facing the first electrode with at least one protrusion portion interposed between the first electrode and the second electrode; and dielectric bodies being disposed between the first electrode and the second electrode and including a first dielectric body and a second dielectric body. The first dielectric body is brought into contact with both of a topmost portion of at least one protrusion portion and the second electrode and positioned therebetween. The second dielectric body is positioned between the first electrode excluding at least one protrusion portion and the first dielectric body.SELECTED DRAWING: Figure 1
