As living standards improve, people's growing awareness of health, blood

pressure is often health care, early detection of diseases one of the principal

means. At present, although there have been several significant electronic

device available, but the price is high, relatively large measurement errors, the

most accurate or traditional desktop mercury sphygmomanometer, blood

pressure table pointer followed. Both blood pressure (Table) accounted for the

amount of the current society has more than 90% of patients blood pressure

Wireless PrototypePrototypes of the device are smaller than a grain of rice yetembedded with an array of highly sensitive, microscopic

electronic chips, sensors, and transmitters.The device would be injected into a diabetic patientsubcutaneously using a hypodermic needle. Patients wouldthen wear a special watch-like monitor that would receivetransmissions from the sensor so they could track their bloodsugar level throughout the day.The researchers hope to make the device adaptable so thatType 1 diabetics can wirelessly connect the glucose monitor to

a portable insulin pump that would automatically infuse insulininto their body as needed. Type 2 diabetics would use thedevice to monitor their bodys reactions after they eat particularfoods or before or after exercise. It would replace the more

common finger prick blood sugar test that is both painful andtime-consuming.In my opinion, this device will be a dream come true for

diabetics, says Papadimitrakopoulos, associate director of the

Universitys Institute of Materials Science and an expert innanotechnology. It is not only going to improve their standard

of living but it will also help educate people on how to go aboutliving with this disease.

Postdocs and doctoral students from the College of Liberal Artsand Sciences, the Institute of Materials Science, and theSchools of Engineering and Pharmacy who are working on thesensor research include: Santhisagar Vaddiraju, Yan Wang,

Upkar Bhardwaj, Jacqueline Morias, Liangliang Qiang, VincentUstach, Fuad Al-Amoody, Robert Croce, Mukesh Gogna, andSupriya Karmakar.

Currently about 23.6 million children and adults in the UnitedStates, or 7.8 percent of the population, are living with diabetes,according to the American Diabetes Association. The

overwhelming majority of those individuals have Type 2diabetes, which results from the body failing to properly useinsulin, combined with insulin deficiency. Complications fromdiabetes can lead to kidney disease, blindness, and limb

amputation.

Minimizing Tissue DamageAlthough other glucose sensors have been developed,scientists have been stymied by their inability to produce a

product that is at once small enough for implantation, wireless,and able to operate under the skin for prolonged periods oftime. Previous devices have been as large as a watch face andviable for only five to seven days at a time, Burgess says.

When we went about developing this device, we wanted tomake it very small to minimize damage to tissue, she says.Imagine having a splinter in your finger. The body responds

with pain, redness, and swelling, and entombs the objectthough fibrosis or scar tissue, which ultimately interferes withthe sensors readings.To combat that reaction, the research team has been workingfor more than 10 years on developing a biocompatible coating

for the sensor that allows certain fluids to flow into and out ofthe device, yet reduces the chances of inflammation andfibrosis while under the skin.The team has developed a polymer hydrogel loaded withmicrospheres - which are like tiny, microscopic beads - filledwith anti-inflammatory medication.
