Abstract:
1. An insole for a shoe to be worn on a foot of a user, the insole comprising: an upper conductive ground plane layer; an upper compressible insulating layer physically coupled to the upper conductive ground plane layer; a conductive sensor layer physically coupled to the upper compressible insulating layer, the conductive sensor layer comprising one or more sensors are configured to measure a force applied to the insole by the foot of the user; a lower compressible insulating layer physically coupled to conductive sensor layer; a lower conductive ground plane layer physically coupled to the lower compressible insulating layer and electrically coupled to the upper conductive ground plane layer; and at least one computational unit communicatively coupled to the one or more sensors, wherein: the upper conductive ground plane layer and the lower conductive ground plane layer are configured to substantially electrically shield the upper compressible insulating layer, the conductive sensor layer, and the lower compressible insulating layer from the shoe and the foot of the user; the one or more sensors are configured to measure at least one of a first change in a first distance between the upper conductive ground plane layer and the one or more sensors and a second change in a second distance between the lower conductive ground plane layer and the one or more sensors; and the at least one computational unit is configured to determine a force applied to the insole using the at least one of the first change in the first distance or the second change in the second distance.
