Diabetics could soon buy a small urine analyser that measures their glucose
levels accurately enough to make regular trips to hospital unnecessary. The
pen-shaped sensor, from NEC, is far more accurate than the crude paper “litmus”
tests many diabetics use at home. NEC’s sensor uses a fluoride resin to remove
other chemicals. Enzymes in the sensor then react with sugar to produce an
electric current that can be read. NEC says its 拢150 device is almost as
accurate as standard 拢15 000 hospital-based machines.
