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

Statistics on diabetes 7% of the population have diabetes (20.8 million) – new cases of blindness each year % 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. Wanda – 12, has low vision, encouraged to start administering insulin to herself 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.

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

Our Goal… 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. Available voice box in the market work with only certain monitors and are expensive. E.g voice box for Ultra Voicemate Sensocard Glucowatch Voicebox Ultra

Design Considerations Use existing product - test strip based monitor Build voice box for audio output 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 2: Digital signal from LCD (Failed) Approach 3: Analog signal from beeper (Succeeded) 2) Build circuit

Accu Chek Compact circuitry I-V converterPhotodiode sensor Approach 1 Obtaining analog from sensor Failed sensor

ReliOn LCD Logic analyzer Approach 2 Obtaining digital signal from LCD Failed

Accu Chek Compact Plus beeper Approach 3 Obtaining analog signal from beeper Succeeded beeper

Block diagram Speech IC MicroprocessorA/D Speaker Beeper Glucose monitor

Current Status With the help of Dr Karsai, we are now able to tap into the signal of the beeper. We now are trying to rectify the signal and convert it into a digital signal that could be used for our speech chip.

Future work Buy microprocessor and speech chip Program the microprocessor Build voice box

Timeline December Research existing products and clients' needs Produce initial idea Compile resources and materials needed Cost assessment January Review existing materials Design prototype Development of prototype February Development of prototype (continued) Test prototype March Assess problems and failures Redesign and modification Changes to prototype April Compile and present design poster and final results
