Nanowerk  April 27, 2024 Researchers in China developed a contactless user-interactive sensing display (CUISD) based on dynamic alternating current electroluminescence (ACEL) that responds to humidity. Sub second humidity-induced luminescence was achieved by integrating a highly responsive hydrogel into the ACEL layer. The patterned silver nanofiber electrode and luminescence layer, produced through electrospinning and microfabrication, resulted in a stretchable, large-scale, high-resolution, multicolor, and dynamic CUISD. It was implemented for the real-time control of a remote-controlled car, wherein the luminescence signals induced by touchless finger movements were distinguished and encoded to deliver specific commands. The distinctive recognition of breathing facilitates the CUISD […]
