Enhancing the functionality and sensory capabilities of living structures with large-area electronics, presents exciting applications in biology-machine interface and wearable health technologies. Nevertheless, current large-area sensor and electronic designs can pose challenges by interfering with the natural sensations of their biological hosts. Another hurdle is finding ways to expand the use of transient, large-area electronic structures without significantly increasing their environmental and ecological impact. This presentation will demonstrate biofabrication and fibre printing technologies towards sustainable and imperceptible electronics and sensors. Using substrate-free polymeric fibres as building blocks, the fibres naturally form seamlessly interfaces with the biological surfaces, further allowing rigid-flexible coupling with microelectronics and e-textiles. Additionally, we demonstrate a circular approach to device maintenance, recycling, and reconfiguration. An outlook is provided on the future pathways for developing sustainable on-skin electronics and "Fiber-of-Things (FoT)".
