Abstract:
1. A method of making an imprinted micro-wire structure, comprising: providing a substrate; providing first, second, and third different stamps; providing a curable first layer in relation to the substrate; forming imprinted first, second, and third micro-channels in the curable first layer by at least imprinting the curable first layer with the first stamp and curing the curable first layer, the third micro-channel separate from the first and second micro-channels, and the third micro-channel dividing the first layer into first and second portions, the first micro-channel located in the first portion, and the second micro-channel in the second portion; forming a first micro-wire in the first micro-channel, forming a second micro-wire in the second micro-channel, and forming a third micro-wire in the third micro-channel; providing a curable second layer; forming an imprinted first connecting micro-channel and an imprinted second connecting micro-channel in the curable second layer by at least imprinting the curable second layer with the second stamp and curing the curable second layer; forming a first connecting micro-wire in the first connecting micro-channel and forming a second connecting micro-wire in the second connecting micro-channel; providing a curable third layer; forming an imprinted bridge micro-channel in the curable third layer by at least imprinting the curable third layer with the third stamp and curing the curable third layer; and forming a bridge micro-wire in the imprinted bridge micro-channel; wherein i) the first layer is adjacent to and in contact with the second layer, and the second layer is adjacent to and in contact with the third layer; ii) the first connecting micro-channel is formed corresponding to at least a portion of the first micro-channel, the second connecting micro-channel is formed corresponding to at least a portion of the second micro-micro-channel, the first and second connecting micro-channels are separate from the third micro-channel, the imprinted bridge micro-channel is formed corresponding to at least a portion of the first connecting micro-channel and corresponding to at least a portion of the second connecting micro-channel; and iii) the first connecting micro-wire contacts at least a portion of the first micro-wire, the second connecting micro-wire contacts at least a portion of the second micro-wire, the first and second connecting micro-wires are separate from the third micro-wire, and the imprinted bridge micro-channel electrically connects the first micro-wire to the second micro-wire and is electrically isolated from the third micro-wire.
