2. GOALS OF PRESENTATION What is diabetes ?
What are some of the present prototypes for implantable glucose sensors, and what are the drawbacks?
What will the program designed for this implantable sensor do, and how does it function?
How will my program alarm patients of unhealthy glucose levels?
Is my program compatible with the sensor?
How will the program help diabetes patients in the future? 1

3. DIABETES
Lack of insulin produced in the pancreas
Type 1and Type 2
Insulin resistance may occur in the body, along with Hypoglycemia or Hyperglycemia, which may lead to ketoacidosis
Hypoglycemia can cause seizures which must be treated by glucagon.
Patients must regulate their blood glucose levels very closely
347 million people worldwide have diabetes[1]
World Health Organization (WHO)

4. Frequent urination and increased thirst. Quick Solutions Ketoacidosis:
DIABETES
Hypoglycemia:
Shakiness, anxiety, sweating, blurred vision, and headaches
Hyperglycemia:
Frequent urination and increased thirst.
Quick Solutions
Ketoacidosis:
Diabetic coma, excessive amount of ketones
Very common to experience

5. GLUCOSE SENSORS TODAY
Sensors for Medicine and Science (SMSI) has developed
an implantable sensor.
Sleep Well Glucose Monitoring Wearable Band
has proven to be very successful.

6. GLUCOSE SENSORS CONTINUED

7. HEALTH HAZARDS
If the sensors contain batteries, there can be several life-
threatening issues that can occur if not careful.
Batteries can leak acid into the bloodstream which would
almost immediately kill the patient.
Also, batteries can overheat, burning the skin near the wrist
area.

8. HEALTH HAZARDS CONTINUED
One of the main problems with the sensors is potential cell refusal.
Many engineers are testing out new methods of micro-fabrication.

9. LABVIEW PROGRAM
Signal Processing Unit that gives off a frequency proportional to DC current
An Amperometric Electrochemical Sensor Named Potentiostat will generate a current that corresponds to glucose concentration
A Data Acquisition Card will give the frequency values to the Labview Program to generate a square wave graph and value table.
The transmitter will give off a signal that is received by the ZigBee receiving module.

10. DAQ CARD Analog Input and Digital Input are used to acquire signals
Analog Output and Digital Output are for generating signals

11. DAQ
A DAQ assistant must be used in Labview to receive data. The DAQ assistant recognizes the DAQ card that is plugged into the USB port.
The ground wire of the source is connected to the ground pin of the DAQ card.

12. PROCESS OVERVIEW Simulating Signal Read to Text Files
Slope formula conversion
LED lighting

13. LABVIEW

14. LABVIEW CONTINUED

15. SIMULATION SIGNAL 15

16. EQUATIONS y1-y2 = slope slope= glucose1-glucose2
x1-x frequency1-frequency2
Slope of a straight line:
y= mx+c
y= glucose concentrations
m=slope
x= frequency values
c= constant

17. EQUATIONS IN LABVIEW

18. POWERING LEDs Two LEDs were wired to my program using DAQ assistants
and the DAQ card.
The first LED signaled anything less than 3mg/dL, alarming the
patient of hypoglycemic conditions.
The second LED lit when the glucose concentration was
greater than 25mg/dL, to inform the patient about his or her
hyperglycemic condition.

19. LEDs CONTINUED
Port 0 and 1 of Digital Output were used to power the LEDs.
The LED bulbs required 5 Volts to power.
The lights turned on and off, corresponding to the various
hyper or hypoglycemic conditions being shown in the Labview
program.

21. TEST FOR COMPATIBILITY
My Labview Program was
tested with the actual prototype,
seen in the silver box, to test for
compatibility.
The program successfully
received the frequency values
that were given off by the
sensor and converted them to
glucose concentrations.

22. FUTURE OF THIS PROGRAM Eliminate finger pricking.
Alarm patients of dangerous blood glucose levels through LEDs.
Ensure the safety and well-being of many Diabetes patients.
