Abstract:
A pliable pressure sensitive sensor device and method of making the same is provided. The sensor includes first and second pliable protective layers, which cover sets of conductive fibers that spatially separated by an electrically conductive pliable layer, which deforms in response to a pressure event. The fiber sets form a grid pattern and are in electrical communication with sets of electrical contacts located in predetermined locations along the fibers. In response to a pressure event in proximity to the contact, the pliable layer deforms and increases the amount of surface area in contact with an electrical contact whereby an electrical resistance at an individual electrical contact decreases in response to the pressure event.

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.

A pressing force sensor that includes a sensor element configured with a piezoelectric film, a lead terminal for connection to an external circuit, a wiring conductor which connects pressing force detection electrodes and the lead terminal, and a flexible printed circuit board which withstands solder reflow temperatures. The flexible printed circuit board has the pressing force detection electrodes formed on a first principal surface thereof, and is folded via a folding line while the first principal surface faces inward. The sensor element is deflected by a pressing force applied to a second principal surface which faces outward and is in a first area of the flexible printed circuit board which is on one side with respect to the folding line, and a signal corresponding to the pressing force is thus taken out from the pressing force detection electrodes.
