Abstract Background This paper provides an overview of initial research conducted in the development of pressure-sensitive foam and its application in wearable sensing. The foam sensor is composed of polypyrrole-coated polyurethane foam which exhibits a piezo-resistive reaction when exposed to electrical current. The use of this polymer-coated foam is attractive for wearable sensing due to the sensor s retention of desirable mechanical properties similar to those exhibited by textile structures. Methods The development of the foam sensor is described as well as the development of a prototype sensing garment with sensors in several areas on the torso to measure breathing shoulder movement neck movement and scapula pressure. Sensor properties were characterized and data from pilot tests was examined visually. .
