SH-SAW May Give Robots a Sense of Taste

Focuspeck writes, "British researchers at the University of Warwik Sensor Research Lab have created a unique type of electronic tongue that works by rattling and observing the acoustic response of fluids. It appears that different tasting fluids respond to the rattling in specific ways, allowing for detection of the four basic tastes: sour, salty, bitter and sweet. The new technology promises to be miniature, low-cost, robust, durable, and micropowered." The sensor technology used in the new electronic tongue is called a dual shear horizontal surface acoustic wave (SH-SAW) device. Similar acoustic wave technology has been used previously in artificial noses. For more details on the new sensor, see the recent Discoverychannel.com article. An abstract of a recent paper on the sensor is also available.
