A three-dimensional stretchable core–shell cable for soft and hybrid electronics that is patternable, recyclable and noise-resistant
摘要
Soft electronics that can conform to three-dimensional objects are of use in the development of wearable devices. However, it remains challenging to design multiscale and easy-to-pattern stretchable cables that can interface with conductive pads and form reliable interconnects with (soft, rigid and hybrid) terminal electronic units. Here we report a three-dimensional stretchable core–shell cable that is patternable, recyclable and noise-resistant. The fabrication process of the stretchable cables is compatible with multiple-scale manufacturing and has a recycling rate of up to 95%. The cables exhibit a Young modulus of around 0.9 MPa and a maximum stretchability of around 800%, with almost no resistance change under stretching. They can form reliable interfaces with various conductive pads through a room-temperature connection process, and we use them to create cable-connected hybrid electronics that maintain electrical performance under stretching. We show that the cables can be used in wearable physiological monitoring electronics and that the resistance of the stretchable cable is insensitive to mechanical interference.
