some children in the west are diabetic before they leave school,
and the incidence of diabetes in the adult
population is growing at an alarming rate, so this little device could help
sufferers to monitor their sugar levels without being invasive as the present
day finger-prick method, the UCSD team
printed electrodes onto standard temporary tattoo paper and paired it with a
sensor, after each meal, the electrodes generate a current for about 10
minutes, the current draws the glucose—a type of sugar that diabetics have
trouble breaking down—up near the skin's surface, allowing the device to read
the glucose levels, the glucose is carried by sodium ions, which have a
positive charge, by measuring how strong the charge is just under the skin, the
sensor estimates how much glucose is in the bloodstream,
the researchers tested the device on seven non-diabetic
people and found that the tattoo’s glucose measurements were consistent with
the traditional finger-prick testing method. Amay Bandodkar, a nanoengineering
graduate student at UCSD, who worked on the study, said in a news
release that each temporary
tattoo would work for up to a day, and would cost users only a few cents per
tattoo, what a neat idea for people who have a dread of needles and I guess a significant saving in costs on the present day finger-prick method.
