Diabetes
Lack of insulin produced in one’s pancreas, or the insulin is incompatible with one’s body
Insulin serves as a “key”
When you eat, your body turns food into glucoseAt this point, your pancreas releases insulinOpens cells and allows glucose to enter, which provides energy Patients must manage their glucose levels carefully

Causes and SymptomsType 1 and Type 2 are predominant, though Gestational and other types do exist
Type 1 makes up only 5% of the diabetes population
Type 2 is mainly caused by diet or environmental influences
Symptoms include:Extreme thirst or hungerSweet smelling breathKetoacidosis (diabetic coma)Slide4
Today’s MethodsMethods today include finger pricking or urine testing, though finger pricking is more accurate
Europe has a noninvasive measurement device that clips onto one’s earlobe (
GlucoTrack
)Slide5
iBGStar MonitorConnects to an
iPhone
or iPod touch device
Comes with test strips that the patient would apply their blood to, and run the test strip through the deviceSlide6
CGM SensorsA minuscule electrode is inserted under the skin, which measures glucose levels in tissue fluid
Connected to a transmitter that sends information to the device via a wireless radio frequencySlide7
DisadvantagesFinger pricking, while accurate, is painful and difficult for those with physical limitations
Also leads to sensitive and calloused fingertip
An inconvenience to have to do every day for life
Placing sensors under the skin can lead to health hazardsCell rejectionBatteries can leak acid into bloodstream, potentially killing the patientSlide8
Designing a program for sensorsGoal: Provide cheaper sensors while still maintaining accuracy
LabView
: visual programming platform
Process:Receive signal Read and analyze given dataCalculate slopeUse slope and frequencies from signal to calculate unknown blood glucose concentrationsSlide9
LabView Program
Program will allow a wireless chip to monitor glucose levels
Uses correlation between frequencies and blood glucose levels
When levels are dangerously low or high, it gives an alert (LED Signal) Current process includes a signal simulation, use of slope formula, read to text capability

AdvantagesAntiquate finger pricking methods
Allow utmost accuracy by calculating each individual pair of correlations rather than calculating a line of best fit
Save costs (no need for strips or monitors that need to be updated)Slide19
