Abstract

A flexible differential strain sensor, system, and method comprises a deformable substrate having a first axis and a second axis different from the first axis, and a first sensing element and a second sensing element. The first and second sensing elements are composed of a conductive gel. The first sensing element is arranged to detect strain in the deformable substrate along the first axis. The second sensing element has a first portion arranged to detect strain in the deformable substrate along the first axis and a second portion arranged to detect strain in the deformable substrate along the second axis. The second sensing element is arranged to offset at least a portion of the stimulus detected by the first sensing element along the first axis.
