Working on the Design and Build

Image of Sarah working on designing the Prototyping circuit board that will form the basis of Vital Air 2.0. During this Project, Sarah learned how to use a soldering pen to connect wires to circuit boards and sensors. When needed, she used a 2000x digital microscope to magnify the boards to ensure accurate connections.

Emma works on her HP laptop to design schematics for the Vital Air 2.0 Prototype. She and Sarah used TinderCad and Procreate for the design work. Both Emma and Sarah hope to begin learning AutoCad in the near future.

Wiring Schematic

Emma designed the wiring schematic It served as an important guide as Sarah designed and assembled the prototype boards and sensors.

Conductive Fabric

Image of Conductive fabric (top). We used Armour Shield brand conductive fabric. It is woven with silver-coated fibers to make it electrically conductive. Below is an image of conductive fabric magnified using an Andonstar digital microscope AD249S-M, working distance 4.5mm. 2024x magnification with 3x digital zoom. Output to 28" HDMI monitor.

Appreciation to our parents who bought us this microscope.

Mobile App

We designed and built a mobile application that displays streaming biofunction data using IoMT networking. This can be transmitted in real-time to anyone the user chooses. The app is created using Universal Design Principles. It has large buttons and text. The colors are clear with notable contrast. Directions are easy to locate and follow.

Our thanks to Blynk IoT for providing a hosting subscription at a much reduced price which enabled use to use this great platform.

Coding Microprocessor

Pictured is a snippet of novel code written in C++ programing language. The purpose of the code is to program the Arduino Nano RP2040 Connect microprocessor to measure specific biofunctions, in this case, breaths per minute.

Photovoltaic Cells

​We attached a 195mm x 58mm ultra thin (1mm), ultra light weight (20 grams) flexible solar panel to the upper shoulders of the prototype’s garment. The panel is waterproof and fire-resistant. Powered by the sun, it can charge a small battery to provide an alternative or additional power source for the prototype. The gaol was to enhance the energy sustainability of the prototype.

Graphene Expoxy Application

This photo shows a 1"x 2" piece of conductive fabric coated with a Graphene epoxy. The yellowish hue of the silver conductive fabric is the graphene epoxy. Graphene epoxy G6E-FXSG × 2.  Image taken using Andonstar digital microscope AD249S-M . Working distance 4.5mm. 2024x magnification with 3x digital zoom. Output to 28" HDMI monitor.
