| Abstract: |
A capacitive bend sensor includes a first element having a comb-patterned portion of conducting material, and a second element having a comb-patterned portion of conducting material. A dielectric material is disposed between the comb-patterned portion of the first element and the comb-patterned portion of the second element. The first element is bonded to the second element such that the comb-patterned portion of the first element slides relative to the comb-patterned portion of the second element when the first and second elements are bent. Bend angle is measured according to the alignment of the comb-patterned portion of the first element and the comb-patterned portion of the second element. The sensor may be coupled to a human finger to measure bend angle of the finger, or may be coupled to a joint of a human body to measure bend angle of the joint.

We claim:
1. A sensor for measuring bend angle comprising:
- a first element having a comb-patterned portion of conducting material;
- a second element having a comb-patterned portion of conducting material;
- a dielectric material between said comb-patterned portion of said first element and said comb-patterned portion of said second element;
- wherein said first element is bonded to said second element such that said comb-patterned portion of said first element slides relative to said comb-patterned portion of said second element when said first and second elements are bent; and
- wherein said bend angle is measured according to alignment of said comb-patterned portion of said first element and said comb-patterned portion of said second element.
