Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
56 words
A piezoelectric bender transducer comprising, a. a thin strip of polarized piezoeLectric material, b. means supporting said strip in a predetermined orientation while affording bending movement thereof, and c. photovoltaic means formed on a surface of the said strip, the bending movement of the transducer being in correspondence with the voltage developed by the photovoltaic means.
Claim 2
Dependent Claim
21 words
The invention as recited in claim 2, wherein the strip of piezoelectric material is polarized in the direction of its length.
Claim 3
Dependent Claim
20 words
The invention as recited in claim 2, wherein the said photovoltaic means comprises a plurality of individual, spaced photovoltaic cells.
Claim 4
Dependent Claim
40 words
The invention as recited in claim 2, including a second thin strip of polarized piezoelectric material, the two strips of piezoelectric material being bonded together, and second photovoltaic means formed on a surface of said second strip of piezoelectric material.
Claim 5
Dependent Claim
23 words
The invention as recited in claim 5, wherein the two strips of piezoelectric material are polarized in a direction normal to their length.
Claim 6
Dependent Claim
44 words
The invention as recited in claim 2, wherein the means supporting the strip of piezoelectric material is a thin metal strip having the strip of piezoelectric material bonded to a surface thereof, said metal strip having one end portion secured to a support member.
Claim 7
Dependent Claim
38 words
The invention as recited in claim 7, including a second thin strip of piezoelectric material bonded to the other surface of the metal strip, and photovoltaic means formed on the surface of said second strip of piezoelectric material.
Claim 8
Dependent Claim
51 words
The invention as recited in claim 7, wherein the said support member is a mounting block having spaced arms, said one end portion of the metal strip being secured to one of said arms, and the other end portion of the metal strip being secured to the other of said arms.
Claim 9
Dependent Claim
32 words
The invention as recited in claim 9, wherein said mounting block is made of an insulating material, and including means for applying an external voltage across the ends of said metal strip.
