Abstract: A triboelectric device artificial air gap between the two materials to create the voltage potential. A method of using a flexible, compressive material as a spacer to create an artificial air gap that will allow the two materials to transfer electrons and provide a restorative force to separate the two materials when pressed together. The result is a device that does not require an air gap to generate a voltage potential, which in turn reduces the necessary footprint of the triboelectric device to a thin film and improves its mechanical robustness and lifetime.

Abstract: According to one aspect of an inventive concept, a pre-polymer matrix formulation for a polymer dispersed liquid crystal (PDLC) display includes a monofunctional monomer, a trifunctional oligomer, and a trifunctional monomer. According to another aspect of an inventive concept, a product includes a PDLC display formulation comprising a polymer matrix having a plurality of liquid crystal (LC) domains dispersed therein, wherein the polymer matrix comprises a polymerized product of a monofunctional monomer, a trifunctional oligomer, and a trifunctional monomer, and a pair of electrodes having the PDLC display formulation positioned therebetween. The PDLC display formulation is characterized as having a substantially constant optical transparency during application of a low power direct current (DC) electromagnetic field between the electrodes for a predefined duration of time.
