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.

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.
