    摘要: Foamed articles including a foamed thermoplastic elastomeric material, methods of making the articles, and methods for manufacturing articles of footwear, apparel, and athletic equipment incorporating the articles are provided. One exemplary method for making a foamed article comprises placing an article comprising a foamable material and carbon dioxide in a vessel, the foamable material; maintaining the vessel at a first pressure and first temperature at which the carbon dioxide is a liquid and carbon dioxide is soluble in the foamable material; optionally exposing the infused article to a second temperature and second pressure; and subjecting the article to a third pressure and third temperature at which the infused carbon dioxide phase transitions to a gas, thereby expanding the foamable material into a foamed material and forming the foamed article.

    摘要: Foamed articles including a foamed thermoplastic elastomeric material, methods of making the foamed articles, and methods for manufacturing articles of footwear, apparel, and athletic equipment incorporating such foamed articles are provided. In one aspect, a method for making a foamed article comprises placing an article comprising a foamable material and carbon dioxide in a vessel, maintaining the vessel at an infusing pressure and infusing temperature at which the carbon dioxide is a liquid and carbon dioxide is soluble in the foamable material, optionally exposing the infused article to a first intermediary holding temperature and first intermediary holding pressure, and subjecting the article to an expanding pressure and expanding temperature at which the infused carbon dioxide phase transitions to a gas, thereby expanding the foamable material into a foamed material and forming the foamed article.

    摘要: 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.
