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

Our Clients.. 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

Problem Existing blood glucose monitors in the market do not satisfy the needs of all our clients. Also, some of them are quite expensive.

Design Considerations Use existing product - test strip based monitor Build voice box for audio output Build finger placing guide for client with tremor Output : Blood glucose measurement High/Low status - alarm Average measurement

Proposed Design + Voice Box +

Current Status Analyze and understand the glucose monitor circuit Find the analog signal output from the monitor Research for the possible chips/components for voicebox

Future work Design circuitry for voice box Record phrases for voice box Build and test circuit Build finger placing guide
