Pressure sensor and robot hand system
First Claim
1. A pressure sensor comprising:
- an inner flexible insulation substrate;
a plurality of inner electrodes arranged on the inner flexible insulation substrate at a certain distance from each other;
an outer flexible insulation substrate disposed along an outer face of the inner flexible insulating substrate so that the inner electrodes are disposed between the inner flexible insulation substrate and the outer flexible insulation substrate;
a plurality of outer electrodes disposed on an outer face of the outer flexible insulation substrate at a given distance from each other; and
an elastic cover covering the outer face of the outer flexible insulating substrate with the outer electrodes,wherein respective distances between the inner electrodes and the outer electrodes are variable by a pressure applied externally to the elastic cover.

8. A pressure sensor comprising:
-
a flexible insulation substrate including; a conductor wire; a first overlapping portion; a second overlapping portion overlapping with the first overlapping portion; a first through hole formed on the first overlapping portion; and a second through hole formed on the second overlapping portion; and an elastic column, wherein the flexible insulation substrate keeps a three-dimensional shape by bonding the first overlapping potion to the second overlapping portion so that the first through hole and the second through hole are communicated with each other to allow the elastic column to be inserted therethrough.
