Abstract

A sensor system configured for use with an article of apparel includes one or a plurality of sensors formed of a polymeric material having a conductive particulate material dispersed therein and conductive leads connecting the sensors to a port. The leads may also be formed of a polymeric material having a conductive particulate material dispersed therein. The conductive material is dispersed in the sensor(s) at a first dispersion density and the conductive material is dispersed in the leads at a second dispersion density that is higher than the first dispersion density. Each of the sensors is configured to increase in resistance when deformed under pressure, which is detected by a module connected to the port. The second dispersion density is such that each of the leads has sufficient conductivity that the leads are configured to conduct an electronic signal between each sensor and the port in any state of deformation.
