The US Food and Drug Administration is to speed up its review of a new device
called the GlucoWatch, which can painlessly monitor diabetics’ blood sugar
levels. Diabetics who need to perform frequent blood sugar tests have to prick
their fingertips to draw blood, but the watch-like device developed by Cygnus of
California uses an electric current to draw glucose across the skin and into a
pad instead. It measures sugar levels every twenty minutes and sounds an alarm
if they get too low or high. The data can also be downloaded into a
computer.
