Abstract
A triboelectric film and its laminate that utilize a conductive primer are provided. The triboelectric effect is a type of contact electrification such that with a suitable configuration, a current may flow from one region to another. When decorative triboelectric films are touched, electrical charges are built up and the generated electrical charges between a human body and films flow through a conductive primer. This system based on the triboelectric effect and the conductive primer can provide electrical functions to decorative film products without there being any large changes.
Claims8
A triboelectric film laminate, comprising:
- a substrate which acts like an insulator;
- a conductive primer layer disposed over the substrate;
- an adhesive layer disposed over the conductive primer layer;
- a surface layer disposed over the adhesive layer, the surface layer being a decorative film;
- and
- electrodes deposited on the conductive primer layer,
- wherein at least a portion of the conductive primer layer is formed to contact the substrate and partitioned into a plurality of electrically divided regions, and each electrode is in contact with a portion of one of surfaces of the conductive primer layer and provided for each of the electrically divided regions.
A detecting device for sensing triboelectric voltages, comprising:
- first and second substrates, each partitioned from one another and act like an insulator;
- a first conductive primer layer disposed over the first substrate and a second conductive primer layer disposed over the second substrate, wherein the first and second conductive primer layers are partitioned from one another;
- a single adhesive layer disposed over both the first and second conductive primer layers;
- a surface layer disposed over the adhesive layer;
- and
- a load connected on one side to the first conductive primer layer and connected on another side to the second conductive primer layer,
- wherein the first conductive primer layer disposed over the first substrate and the second conductive primer layer disposed over the second substrate are each partitioned to be an electrically divided region.
