Claim Text:
1. A piezoelectric resin blend comprising: (a) a piezoelectrically active polymer that is a polymer or copolymer selected from poly(γ-benzyl α,L-glutamates) (PBLG), vinyl PBLG, polystyrene, polypropylene, low density polypropylene, polyvinylidene fluoride (PVDF), poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)], poly(oxymethylene), nylon 6, nylon 66, nylon 610, epoxies, polyurethanes, cellulose, foam fluorinated ethylene propylene copolymer (FEP), glass beaded fluorinated ethylene propylene copolymer (FEP), porous polytetrafluoroethylene (PTFE), glass resins, or mixtures thereof; (b) monomers for the formation of a matrix polymer that is poly(methylmethacrylate) (PMMA), polyethylene, polyvinylchloride, poly(l-butene), or a silicone elastomer; and wherein the piezoelectric polymer comprises from about 5% to about 50% (w/w) of the resin blend.
