Scalable and stretchable 1D multifunctional fibers for multimodal sensing and stimulation

One-dimensional (1D) multifunctional fibers have garnered significant attention due to their advantageous geometry properties, which allows conformal interfacing with soft biological tissues and efficient charge transport. Here, we developed a solution-deposition strategy for the scalable and cost-effective fabrication of stretchable liquid metal fibers integrated with electrochemically stable, tissue-interfacing electrodes, thereby enabling the realization of stretchable multifunctional fibers. This fiber seamlessly combines electrodes and conductive pathways into a single structure, enabling versatile applications such as electrophysiological signal sensing, in vivo nerve stimulation, and wireless energy…
