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

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
