Nanowerk  November 3, 2021 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 […]
