Korean scientist invents robotic tongue
KOREAN scientists have invented a robotic tongue, they claim.
Bae Young-min and Seoul National University professor Cho Seong-in have, according to the American Society of Agricultural Engineers (or ASAE), will be given the 2003 ASAE Superior Paper Award for their research on the "Response of Polymer Membranes as Sensing Elements for an Electronic Tongue."
The krazy Korean's robotic tongue comprises a sensor array and data processing parts.
Bae said to the Korean Times that the sensory component of the system is compatible to the human tongue, and includes three positive ion sensors, two negative ion sensors and a hydrogen sensor.
They react to electrolytes corresponding to salty and acidic tastes, and create electronic signals through the sensor arrays.
