Abstract
A device for promoting healing of an injury in a living being is provided. Such device is based upon an injury covering portion, which portion comprises an electroactive polymer, such as poled polyvinylidine difluoride (PVDF) or a copolymer of PVDF. The electroactive polymer has either pyroelectric properties, piezoelectric properties, or both.
Claims6
A device comprising:
- an injury covering portion configured to promote healing of an injury in a living being without the need to apply voltage during use and comprising a porous multilayer fiber mat comprising a plurality of layers, wherein each layer comprises a plurality of non-woven electroactive polymer fibers, wherein all of the fibers in a layer are aligned with and substantially parallel to one another, the fibers having both pyroelectric and piezoelectric properties, and the fibers comprising a poled polyvinylidine difluoride or a poled copolymer of polyvinylidine difluoride, wherein the fibers are electrospun.
