2016 Wearable Devices Incorporating Nanotechnology
Ask
Plan
● Research current wearable devices
● Dr. Michael Daniele encourages team to measure electrical impedance and how it decreases as dehydration increases.
● Shift to a Galvanic Skin Response Sensor and diagram prototype based on function.
Improve
Create.
Imagine● Identify dehydration as symptom of malnutrition in both flora and
fauna
● Brainstorm products that may address the problem of dehydration
● Create mind map to summarize the 5 tenets of One Health

● Use the Arduino LilyPad, connect GSR sensor (Galvanic Skin
Response) with an LED light
● Program LED to light up when electrical impedance increases
over a certain threshold.
● Mount to wrist for easy and joint-free access.
● Test prototype and adjust pre-programmed threshold settings.
Open Air
Testing
● Run baseline data
● Sensors not reliable when worn around the wrist
● Redesign from bracelet to head band.
● Test again
● What global health issues can we address with a wearable device?
● The One Health Challenge connects the health of humans, animals
and plants.
Our team would like to thank the ASSIST Program, Kenan Fellows Program, Dr. Jesse Jur, Dr. Elena Veety, Dr. Russell Gorga, James Lamberth, and Hannah Maxwell and all the individuals who collaborated and contributed to make this program a worthwhile venture for all teachers and our students.
