Current printing techniques for printing soft electronics (PSE) are still facing long-lasting challenges in addressing the conflict between printing speed and performance. A team of researchers in the US (California Polytechnic State University, UC San Diego, University of South Florida, Carnegie Mellon University) has developed a new corona-enabled electrostatic printing (CEP) technique for ultra-fast roll-to-roll (R2R) manufacturing of binder-free multifunctional e-skins. CEP-printed graphene e-skins were demonstrated to possess an outstanding strain sensing performance. The binder-free feature of the CEP-assembled networks enables them to provide pressure sensitivity as low as 2.5 Pa and capability to detect acoustic signals of hundreds of hertz in frequency. They used the technique to pattern different types of functional materials (e.g., graphene and thermochromic polymers) onto different substrates (e.g., tape and textile). According to the researchers CEP manufacturing platform is compatible with the R2R process for fabricating high-performance, scalable, and low-cost soft electronics…read more. TECHNICAL ARTICLEÂ
