Artificial tongue made from polymer gel

15-Feb-2013 - China

By measuring how the gels swell, bend and fluorescence, the researchers found that the gels selectively respond to and can distinguish between sourness (citric acid and gluconic acid), sweetness (glucose), saltiness (sodium chloride) and umami (sodium glutamate).
