ALS patients communicate with a wearable sensor

From MIT’s Media Lab:  “The wearable includes a silicone film that contains four piezoelectric sensors. The sensors can detect deformation of the underlying skin and convert this to an electrical signal. This could mean that gentle facial expressions, such as a smile or twitch, could be registered as specific messages, such as “I’m hungry”. These facial movements, alone or in combination, could correspond to a library of phrases, aiding rapid communication.”     MORE
