a–d The I-V curves of \({{{\mathrm{PU}}}}_{200\% }^{420{{{\mathrm{D}}}}}\) @PPy at different strains (200%, 500%, 900%, and recovery). e The 1500 cyclic loading-unloading test of \({{{\mathrm{PU}}}}_{200\% }^{420{{{\mathrm{D}}}}}\) @PPy under 20% strain. Inset shows 5 cycles at the beginning and the end of the 1500 cycles, respectively. f Schematics for dual bending (pink) and stretching (purple) deformation for human body movement. g Stretching-bending instrument for the filament. h Real-time resistance change of the filament during a stretching-bending process.
