▎ 摘　　要

NOVELTY - The pressure sensor array (100) has a pressure-sensing substrate (110) that is provided with piezoresistive material. A fabric (150) is divided into several filling portions (151) and a non-filling portion (152). The filling portions of the fabric are separated with each other by the non-filling portion of the fabric. The non-filling portion of the fabric is not filled with the piezoresistive material (140). Several pressure-sensing columns (160) are electrically separated with each other by the non-filling portion of the fabric. Each pressure-sensing column is provided with a respective filling portion of the fabric and the piezoresistive material. The respective filling portion of the fabric is filled with the piezoresistive material. Each pressure-sensing column is provided with top column surface (161) and a bottom column surface (162). USE - Pressure sensor array for pressure mapping system (claimed) used in wearable and light-weighted electronic product. ADVANTAGE - The spraying of the piezoresistive ink is performed with 2-5 times for improving sensor-to-sensor uniformity. The top surface of the non-filling portion and the plastic cover are stuck together by glue for preventing the glue from affecting conductivity of the pressure-sensing column and the silver-coated yarn. DETAILED DESCRIPTION - The piezoresistive ink comprises a polymer, a conductive material and a solvent. The polymer has a concentration between 1-10 wt.%, the conductive material has a concentration between 0.1-2 wt.% and the solvent has a concentration between 90-95 wt.%. The polymer is thermoplastic polyurethane (TPU), polyurethane (PU), phenoxy resin, polyacid, polyacrylic acid, polyacrylate, N,N'-dimethylol-4,5-dihydroxyethylene urea (DMDHEU) resin, poly(vinyl alcohol) (PVA), or polyethylene glycol (PEG). The metal particles are made of silver or copper. The conductive carbon material is carbon black, carbon nanotubes, graphene, and/or graphite. The conductive material is metal particles or a conductive carbon material. The fabric is a cotton fabric or a blended fabric. Each of the first metal-coated yarn and the second metal-coated yarn is a silver-coated yarn, stainless steel-coated yarn, or a copper-coated yarn. An INDEPENDENT CLAIM is included for method for fabricating a pressure sensor array comprising, which involves providing a fabric divided into filling portions and a non-filling portion, placing a mold having holes on a first surface of the fabric such that filling portions of the fabric is exposed to the plurality of holes, curing the piezoresistive ink in the partially piezoresistive ink-soaked fabric such that each filling portion of the fabric is filled with a piezoresistive material formed from the piezoresistive ink, forming a pressure-sensing substrate comprising pressure-sensing columns electrically separated with each other by the non-filling portion of the fabric, connecting each top electrode of top electrodes to respective top column surfaces and connecting each bottom electrode of bottom electrodes to respective bottom column surfaces for forming the flexible pressure sensor array. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a flexible pressure sensor array.
