A Wearable Graphene Strain Gauge Sensor with Haptic Feedback for Silent Communications

Silent communication devices are necessary in situations when audio voice signals cannot be relied upon. This could be due to physical voice impairments of the sender, or being in an environment in which sound cannot be transferred reliably or securely. A wearable ultrasensitive strain sensor worn on the throat may be able to detect small muscle movements and vibrations which can be mapped to the ...
