ANGULAR DISPLACEMENT SENSOR OF COMPLIANT MATERIAL

摘要

Disclosed is a sensing device that includes a flexible substrate having an elongated structure extending between a first end and a second end, the elongated structure being compliant material that is flexible and bendable from a linear, non-bent position to multiple bendable positions. The sensing device also includes a first compliant strain sensing element embedded within the compliant material and extending between the first end and the second end along a longitudinal length of the elongated structure. The first compliant strain sensing element includes a second compliant material that is flexible and bendable, where an electrical property of the first compliant strain sensing element changes in proportion to an applied strain on the elongated structure.
