Mask-free printable alternating-current electroluminescent film

Abstract

A stretchable and flexible electroluminescent film may include a bottom substrate layer and a bottom electrode layer on the substrate layer. A dielectric layer may be included on the bottom electrode layer. An electroluminescent layer may be included on the dielectric layer. The electroluminescent layer may illuminate in response to an electric field. The film may further include a top electrode layer configured to provide the electromagnetic field with the bottom electrode layer. The film may further include a top substrate layer on the electrode layer. The bottom substrate layer, the bottom electrode layer, the dielectric layer and the electroluminescent layer each include an elastomeric polymer. The film may be printer layer by layer using a mask-free additive manufacturing process.
