Abstract: Disclosed is a first force sensing region of footwear. The first force sensing region includes a first force sensor unit. The first force sensor unit includes a first compliant capacitor disposed with respect to a first plane. The first force sensor unit also includes a strain transformation structure disposed with respect to the first plane. The strain transformation structure includes a first transformation element coupled to an outer surface of the first electrode of the first compliant capacitor and a second transformation element coupled to an outer surface of the second electrode of the first compliant capacitor.

Abstract: Disclosed embodiments include systems and methods for additively manufacturing (e.g., by “printing” or the like) a bend sensor as a 2D structure that can then be configured into a 3D or stacked structure. Further disclosed embodiments include bend sensors with foldable sensing regions configurable into a 3D or stacked structure. A differential strain in a sensing region is linearly proportional to the displacement as measured from the endpoints of the sensing region. The differential strain is measurable as a differential change in the capacitance of the sensing regions.

Abstract: An apparatus includes a strand of compliant material with a center axis. The apparatus further includes a multi-region angular displacement sensor connected to the strand. The multi-region angular displacement sensor includes a first angular displacement unit in a first sense region of the stand. The first angular displacement unit is used to determine a first angular displacement in response to deformation of the first angular displacement unit. The multi-region angular displacement sensor also includes a second angular displacement unit disposed in a second sense region of the strand. The second angular displacement unit is used to determine a second angular displacement in response to deformation of the second angular displacement unit.
