Innovative Graphene-Based Wearable Sensor Allows Detection and Broadcast of Silently Mouthed Phrases Introduction The development of a 'smart' wearable choker featuring ultrasensitive textile strain sensors may significantly advance the Silent S peech Interface (SSI) domain, researchers claim. SSI systems offer a breakthrough solution for scenarios where verbal communication is com promised, such as in noisy environments or for individuals with s peech difficulties, facilitating s peechless communication via electronic li p-reading and human-com puter interaction. Develo pment and Technology Advanced Sensor Design Researchers at the University of Cambridge have develo ped a textile strain sensor with a gra phene overlay, offering enhanced robustness in s peech recognition, even in environments with significant background noise. The smart choker, worn around the neck, detects subtle micro-movements in the throat, which the strain sensor converts into electrical signals. These s...
