Direct Pen Writing of High-Tc, Flexible Magnesium Diboride Superconducting Arrays

High-T-c, flexible MgB2-nanowire-based superconducting arrays are fabricated via a direct pen writing method on both copper foils and poly(dimethylsiloxane) (PDMS) substrates. Such superconducting arrays constitute a new approach for fabricating superconducting devices. The realization of a PDMS-based device demonstrates the potential for expanding this material into other high-T-c superconductor systems, which may lead to novel ways of driving the development of real-life applications.
