Braille is an essential implement for the blind to communicate with outside, but traditional limited a paper-based format that cannot directly provide real-time word information. In this work, flexible virtual electrotactile proposed can benefit from blocked interaction. The interface, S-shaped wires and sphere electrode textile fingerstall integrated by silicone, offers flexibility simultaneously generates microgap through cracks, which achieves sensation electrostatic discharge. Powered high-voltage triboelectric generator of 10.2 kV designed charge accumulation induction strategy, stimulation realized discharge only 40 μA current induced on finger. A dynamic finally assembled, controlled programmable relay array. strategies short circuit voice reminder are employed, so recognition letters spatiotemporal high accuracy. This brings convenience access information world illustrates its applications promote electrotactility in special community.
