Abstract: A pressure distribution mapping system includes a flexible M×N textile-based pressure sensor array. with first and second electrode textile layers and a piezoresistive fabric layer with a sheet resistance of at least 60 k-ohm/square positioned between the first and second electrode textile layers. Individual pressure sensors are formed by an intersection between a row electrically-conductive path and a column electrically-conductive path along with the portion of the piezoresistive layer positioned at the intersection. A measurement system measures the resistance of each pressure sensor of the pressure sensor array. The measurement system includes a reading module with first op-amps connected to each row and second op-amps connected to each column. Plural switches switch between pressure sensor-enabled and pressure sensor-disabled positions to minimize a bus line crosstalk effect during pressure sensor reading A processor scans each pressure sensor and generates a pressure distribution profile based on a measured resistance of each pressure sensor.

Abstract: The present disclosure provides a flexible pressure sensor array and method for fabricating the same. The pressure sensor array comprises a pressure-sensing substrate, top electrodes and bottom electrodes. The pressure-sensing substrate comprises a piezoresistive material, a fabric and pressure-sensing columns. The top electrodes and the bottom electrodes are attached to the pressure-sensing columns. The pressure sensor array is ultra-flexible and conforms to 3-dimensional surface for pressure monitoring.

Abstract: A solventless method of making a dry electrode for an electrochemical cell is provided. A solventless electrode material mixture includes 85-99% electrode active material and from 0-10% conductive carbon additive. A polymer binder system is present from 1-15%. The polymer binder system includes one or more polymer binders. The electrode material mixture is mixed at a temperature greater than a softening point or a melting point of at least one polymer binder of the polymer binder system. The electrode material mixture is kneaded into an electrode material dough. The electrode material dough is formed into an electrode material sheet. At least a portion of the electrode material sheet is affixed to a metal current collector to form an electrode.
