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 application provides a sublimation ink which is capable of being transferred to natural fiber fabrics, such as cotton and linen, in addition to synthetic fabrics, such as polyester, nylon, etc., and shows significantly improved color fastness. The sublimation ink may include a resin containing at least one active hydrogen, a crosslinking agent having at least two isocyanate (—NCO) groups, and one or more colorants. The sublimation ink may also include one or more carriers, binders, thickeners, and/or solvents. An image can be printed on a transfer medium (e.g. paper) at room temperature with the sublimation ink using conventional offset printer so that the sublimation ink remains inactive. The image can be subsequently transferred onto any desired fabrics under heat and pressure, in which the sublimation ink is activated and bonds the colorant to the fabrics with excellent color effect.
