Engineers at the university of Florida have designed sensors that can be used for the application of monitoring diabetics glucose levels from the breadth. The technology used here is the same which is widely used for making chips in cell phones & other electronic devices . The sensors work by mating different reactive substances with gallium nitrade commonly used in amplifiers in cellphones and other electronic applications. At 100 micros, or 100 millionths of a metre, this sensor is so small that the moisture from one breadth is enough to get a concentrated reading. Cost is as little as Rs 10 or 20 cents, but is likely to increase when it would be converted to make an equipment to wirelessly transmit to PCs or cellphones. The entire package might cost around $40 or Rs 1800, and could be halved with mass production.
