Nanowire Percolation Network Conductor

Printed and flexible electronics often replace solid metal films with a random mesh of conductive nanowires deposited on a polymer substrate. This simulator scatters that mesh in 3D: below a critical density the wires form only disconnected islands and the film stays insulating; cross the percolation threshold and a continuous conducting path snaps into existence, tracked live as the shortest active chain of junctions from one electrode pad to the other. Stretching the film then peels off the weakest, most shallow-angle junctions first, so conductance fades gracefully — in contrast to a rigid metal film, which has no redundant paths and cracks all at once.
