US Patent 10959644 Compliant sensors for force sensing

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.
