Piezoelectric actuator sensitive to reducing gas
First Claim
1. A piezoelectric actuator subjected to bending displacement by sensing a reducing gas, said piezoelectric actuator being composed of two regions bonded to each other, one of said regions being made of a material whose electric resistance varies by sensing a reducing gas, and the other of said regions being made of a piezoelectric material which is not sensitive to a reducing gas, an electrode being formed on an outer surface of each region to apply an electric field to said piezoelectric material.

Abstract
A piezoelectric actuator subjected to bending displacement by sensing a reducing gas is composed of two regions bonded to each other, one of the regions being made of a material whose electric resistance varies by sensing a reducing gas, and the other of the regions being made of a piezoelectric material which is not sensitive to a reducing gas, an electrode being formed on an outer surface of each region to apply an electric field to the piezoelectric material.
