摘要：
A fabric with an integrated piezoelectric sensor array and optionally with an integrated display； the fabric may be mounted to the surface of an object to be measured or monitored. The fabric may comprise multiple laminar layers, such as sensor layers, processing layers, display layers, and cladding layers for protection and sealing. The array of piezoelectric sensors may be produced in any desired shape or pattern using various fabrication techniques, including for example: rigid piezoelectric ceramic materials mounted on a flexible substrate； composite material applied as thick films that contain piezoelectric ceramic materials embedded in a polymer matrix, for example with 0-3 connectivity； piezoelectric polymer films； and piezoelectric fibers, such as polymer fibers or polymer-carbon nanotube composites woven into a fabric. Piezoelectric materials may include for example PZT, piezoelectric polymers such as PVDF or PVDF-TrFE, and lead-free ceramic piezoelectric materials such as BT, BNT, BKT, KNN, and BZT-BCT.
