Inspiration

We were inspired by our own experiences with periods--from staining our pants in school to being diagnosed with hormone imbalances. Menstrual blood and our period cycles have immense information to give us about our own healths, right at our fingertips, and it seems a shame to let it go to waste.

What it does

Our product is an attachable device with multiple sensors in it, capable of sending that information to our mobile app. The information collected includes the pad saturation, blood color, period heaviness, and consistency of the blood and clots. This is all presented in the app in a clear and informative way, providing analyses of the information collected as well--such as what different period colors mean about the user's health.

How we built it

We built the app using Android Studio, coded with Java and XML. The device was made with Arduino sensors and sealed in a transparent box. The data was all directed to Firebase, a secure database created by Google.

Challenges we ran into

We did face a few issues with the Arduino sensors and the multiple pins that had to be used to connect the many sensors to the single wifi chip. Also, we faced issues with the detection of consistency, as detecting clots was difficult with a pressure sensor only in certain areas.

Accomplishments that we're proud of

We were extremely proud of the saturation sensor in particular--it was capable of detecting how saturated the pad was very well. Also, we loved the UI/UX we designed for the app.

What we learned

We learned far more about our own menstrual health and what to look out for--as well as working with technologies such as Android Studio and Arduino.

What's next for SmartFlow

We aim to ML algorithms to personalise and calibrate the device better instead of using preset fixed thresholds for decision-making. We also aim to iterate over the design of the device to make it slim, minimalistic, and cover the entire surface area of the underside of the pad. We also want to do additional data processing to gain further insights into menstrual health.
