Wireless Stand‐Alone Trimodal Interactive Display Enabled by Direct Capacitive Coupling (Adv. Mater. 37/2022)

Interactive Displays A wireless stand-alone trimodal interactive display is developed by Cheolmin Park and co-workers, as reported in article number 2204760, where finger touch is displayed with three types of outputs of field-induced electroluminescence, inverse piezoelectric sound, and tactile vibration, and remotely powered by the unique AC-to-AC power transfer based on direct capacitive coupling, making the device potentially suitable for a smart braille display.
