摘要:Portable devices have become lightweight, flexible, and even stretchable such that skin-like electronics are widely applicable, including in biomedical devices, soft robotics, and human/machine interfaces. Rendering these devices soft and flexible is highly desirable, as this would enable them to interact seamlessly with human skin and improve their wearing comfort. We demonstrate a convenient but effective method to fabricate flexible conducting films. These films consist of electrospun polyurethane (PU) fibers as the flexible substrate onto which copper was deposited. These Cu-PU films have excellent conductivity, and their resistance only increases slightly after extensive folding, even when folded into a paper crane with a resistance of 1.8 omega. Furthermore, Cu-PU films can sense tension strength and exhibit stable Joule electrothermal performance. The Cu-PU-based heating glove could be heated to 40 degrees C in 30 s by applying 2 V. The simple but effective procedure presented here is suitable to fabricate flexible conducting film and may also promote the development of portable and flexible electronic products.
