Pictures of the objects are captured using a tiny external camera and then images are converted into a pattern of electronic impulses and sent them to the electrode array placed atop the tongue. The impulses are then sent to the different sensory centers of the brain for interpretation through an electrode array placed on the tongue.
Wearable Bio-Sensors (WBS) will permit continuous cardiovascular (CV) monitoring in a number of novels settings. WBS could play an important role in the wireless surveillance of people during hazardous operations (military, firefighting, etc) or such sensors could be dispensed during a mass civilian casualty occurrence. They typically rely on wireless, miniature sensors enclosed in ring or a shirt. They take advantage of handheld units to temporarily store physiological data and then periodically upload that data to a database server via wireless LAN or a Cradle that allow internet connection and used for clinical diagnosis.
