| 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 time-consuming drying process of those additives is the major hinder for the 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 of dry powders in strong electric field. Dry graphene, CNT, silver nanowire, and many kinds functional powders can be printed. The printing speed can reach as high as 50 cm2/s. The specially printed and naturally formed 3D structure offered high flexibility and sensitivity, allowing our skin-like sensors able to detect sound in frequency as high as hundreds of hertz with high repeatability and reliability. This technology opens the new door for fast and low-cost high-performance flexible sensor processing. |
