Project background National Student Design Competition National Student Design Competition Project Choice: Accessible Blood Glucose Monitor Project Choice: Accessible Blood Glucose Monitor Funding: $ 2000 Funding: $ 2000 Advisor: Professor Baudenbacher Advisor: Professor Baudenbacher

Statistics on diabetes 7% of the population have diabetes (20.8 million) 7% of the population have diabetes (20.8 million) – new cases of blindness each year – new cases of blindness each year % of diabetic have mild to severe form of nervous system damage 60-70% of diabetic have mild to severe form of nervous system damage

Our Clients.. All clients have diabetes Dave – 22, has limited use of his right arm and leg. Dave – 22, has limited use of his right arm and leg. Wanda – 12, has low vision, encouraged to start administering insulin to herself Wanda – 12, has low vision, encouraged to start administering insulin to herself Lloyd – 80, has some hearing loss and is very overweight (400lbs). Lloyd – 80, has some hearing loss and is very overweight (400lbs). Arnold - has Parkinson’s disease, and experiences slight to moderate tremors. He lives alone. Arnold - has Parkinson’s disease, and experiences slight to moderate tremors. He lives alone.

Project Goal  The blood glucose monitor must communicate effectively communicate effectively visual display and voice output. visual display and voice output. calibration and expiration dates of test strips calibration and expiration dates of test strips ease of learning, storage of all components, cleaning and maintenance. ease of learning, storage of all components, cleaning and maintenance. affordable and portable affordable and portable

Our Goal… To win the First Prize for the competition, receive the $1000 cash prize. To win the First Prize for the competition, receive the $1000 cash prize.

Problem Existing blood glucose monitors in the market do not satisfy the needs of all our clients. Also, some of them are quite expensive. Existing blood glucose monitors in the market do not satisfy the needs of all our clients. Also, some of them are quite expensive. Available voice box in the market work with only certain monitors and are expensive. E.g voice box for Ultra Available voice box in the market work with only certain monitors and are expensive. E.g voice box for Ultra

Design Considerations Use existing product - test strip based monitor Use existing product - test strip based monitor Build voice box for audio output Build voice box for audio output Build finger placing guide for client with tremor Build finger placing guide for client with tremor

Proposed Design + Voice Box + Blood Glucose Monitor

Technical Steps 1) Obtaining signal from glucose monitor Approach 1: Analog signal from sensor (Failed) Approach 1: Analog signal from sensor (Failed) Approach 2: Digital signal from LCD (Failed) Approach 2: Digital signal from LCD (Failed) Approach 3: Analog signal from beeper (Succeeded) Approach 3: Analog signal from beeper (Succeeded) 2) Build circuit

Accu Chek Compact Plus beeper Current Status Similar to Accu Chek Compact – but has beeper to signify the results e.g – ‘2’ will have two beeps The signal we obtained from Accu Chek Compact Plus is from the beeper

Current Status We are now trying to rectify the signal and convert it into a digital signal that could be used for our speech chip. We are now trying to rectify the signal and convert it into a digital signal that could be used for our speech chip.
