Abstract
A stretchable wire assembly includes a metal wire coupled between two elastic substrates. The two elastic substrates are selectively coupled together, and the metal wire is attached to one or both elastic substrates at select locations. The form of the metal wire is such that when the elastic substrates are in a relaxed, or non-stretched, state the metal wire forms a tortuous path, such as a waveform, along the coupled elastic substrates. The tortuous path of the metal wire provides slack such that as the elastic substrates are stretched the slack is taken up. Once released, the elastic substrates move from the stretched position to the relaxed, non-stretched position, and slack is reintroduced into the metal wire in the form of the original tortuous path.
