Digital Angel awarded patent for breakthrough Glucose-
Sensing RFID Microchip
November 2, 2006 - The U.S. Patent and Trademark Office
has granted Digital Angel Corporation a patent for its syringe-
implantable glucose-sensing RFID microchip, Digital Angel
announced today. The RFID microchip measures the glucose
concentration levels of diabetic patients and will be marketed
and distributed by Digital Angel's sister company, VeriChip, as
an extension to the company's products benefiting people.
"A glucose-sensing microchip could profoundly impact the 230
million people worldwide living with diabetes," said Digital Angel
CEO and President, Kevin McGrath. "Patent approval for this
RFID microchip is a major step in bringing this life-altering
technology to market. It also underscores Digital Angel's
commitment to innovation, product development and rapid
growth."
Checking blood glucose levels regularly is critical to properly
managing diabetes. The conventional method =96 a finger prick
=96 is invasive, painful and often inaccurate. The implantable bio-
sensor chip has a passive transponder, glucose sensor and
integrated circuitry that allow anyone implanted with the
microchip to painlessly scan it to determine their level of
glucose concentration. The RFID microchip quickly and
accurately transmits the glucose data back to a wireless
scanner that displays the glucose level. The RFID microchip is
powered by the scanner signal, avoiding the need for a
battery in the microchip.

Hand-held glucose meters measure glucose in the entire blood
sample -- glucose that is present in the plasma and the red
blood cells (RBCs). The glucose from the RBCs equilibrates with
the glucose from the plasma portion as the test is being
performed. However, in cats and dogs, the distribution of
glucose between the RBCs and plasma is significantly different
than in humans. This causes the meters that are calibrated to
human blood to read low. The AlphaTRAK glucose monitor has
been developed to account for these differences in RBCs, thus
providing extremely accurate glucose results.

A 2mm-wide implant keeps tabs on blood sugar.
Diabetics are finger-prickers by necessity, but a reprieve may
be in store for their sore digits. A bean-size sensor, slipped
under the skin and read wirelessly, could take the pain and
hassle out of blood-sugar monitoring. The system "listens to
the vibrations of the sensor inside you" to measure glucose
levels, says the inventor, Craig Grimes, an electrical engineer at
Penn State University.
Grimes's implant consists of a magnetic sensor (similar to those
used in anti-shoplifting tags) that vibrates in response to
specific radio frequencies. To turn the sensor into a sugar
monitor, Grimes coated it with two unique polymers: One layer
converts glucose into an acid, the other detects changes in
pH. When acidity increases, the pH-sensitive polymer shrinks,
causing the sensor's mass to decrease and its resonance, or
vibrational frequency, to increase.
A monitoring device worn on the wrist houses a magnetic coil
that detects resonance changes. "You just wave whatever
body part past [the monitor]," Grimes says, and a millisecond
later, you have your glucose reading. The system is testing
well in animals, and Grimes says clinical trials could begin within
a year.
