A neck-worn temporary tattoo that translates the motion of the throat into sounds could give a new voice to those that have lost theirs.
Developed by a team from Tsinghua University, the Wearable Artificial Graphene Throat (WAGT) can be applied with water, adhering to the neck and detecting the movements of the larynx and vocal cords. That information is then transmitted to a hardwired system worn on an armband that ‘speaks’ the word. Though the system’s translations are currently limited, the team hopes the WAGT system could one day prove valuable to people who have lost the ability to speak through accident or disease.
