When it was employed as a flexible substrate film (0.1\u00a0mm thickness), it reliably supported printed conductive traces, demonstrating stable electrical signal output under cyclic deformation. Furthermore, the substrate attached to fingers and wrists successfully monitored bending motions through consistent electrical responses, highlighting its potential for flexible strain sensors. Notably, the printed circuits can be completely removed by soaking in anhydrous ethanol for 12\u00a0h, enabling the full recovery and reuse of the substrate film. This spider\u2010silk\u2010inspired strategy provides a new design pathway for developing strong, tough, and sustainable polymer substrates for next\u2010generation flexible electronics.\n
