| Abstract Scope |
Flexible skin-like sensors are essential for future human health monitoring and therapeutic treatment. Organic additives are often mixed into the functional components to offer the flexibility of the printed flexible sensors. However, the drying process is highly time-consuming, which is the bottle-neck to realize low-cost and fast R2R printing of flexible sensors. We present a new R2R printing technology by taking advantage of the "induction induced absorption" behavior caused by controllable electric field. Dry graphene, CNT, silver nanowire, and many kinds functional nanomaterials can be printed. The printing speed can reach as high as 50 cm2/s. The specially assembled 3D structures offer high flexibility and sensitivity, allowing our skin-like sensors able to detect pressure as low as 2.5 Pa, as well as sound frequency in hundreds of hertz. This technology opens the new door for fast and low-cost nanomaterial assembly and high-performance flexible sensor processing. |
