Inspiration
We were inspired by many current health oriented apparel, such as the whoop watch. However, we were driven to create something that you wont forget to put on in the morning and that you will not forget to charge.
What it does
Our design uses embedded sensors that continuously tracks data and compares it with baseline healthy data. It is paired with a companion health app that displays the data and sends alerts if your vitals or sensor data is not normal.
How we built it
We designed a hardware stack around the Nordic nRF52840 MCU, MAX30102 PPG sensor, six FSR-400 pressure films, and NTC thermistors, all embedded in a shoe insole with a 9mm profile height, designed in AutoCAD.
Challenges we ran into
We struggled with the placement of the electrical and sensor components because the insole is designed to flex, however, the components must remain fairly steady. We also struggled with designing a insert that offers foot support as well as houses all of the necessary sensor components.
Accomplishments that we're proud of
We are proud of our final design and realistic size of the insert. We are also proud of the diagnostics that is backed by real sensor data and can lead to helping real people.
What we learned
We learned the surprising amount of data you can obtain from the bottom of your foot. As well as what goes into pairing raw data together to come to a diagnosis.
What's next for Heart N' Sole
The next step, pun intended, is to make a physical prototype that monitors the sensor data that we can then validate to see if this will be a reliable source of information.
