EnerFlow

EnerFlow is a smart wearable that helps reduce injury risk during workouts by tracking physical strain.

This project began with the observation that people are more likely to get injured when working out alone without a trainer. I explored how AI could take on the role of a fitness coach by monitoring muscle engagement and movement in real time, helping users correct their form and reduce injury risk.

"During the process, the real work was turning AI detection into feedback people can actually act on mid-workout."

Arduino Coding

If the garment is no longer used for workouts, it can be switched to a basic monitoring mode. In this mode, it can be worn by any adult to track physical data, and is especially useful for helping families monitor the health of older users.

This project helped me realize that design doesn’t stop at making a product. It also involves thinking about how people use it over time and what they might need next. If EnerFlow continues to develop, I would look beyond the garment itself and consider its stakeholders and the broader service around it, expanding the project into a more connected system.

This app supports the garment’s monitoring mode, where AI shifts from a fitness coach to a personal health assistant. It tracks broader physical data and offers general insights and improvement suggestions. While not intended for medical diagnosis or treatment, it serves as an early alert to help users notice potential issues.

Before the final design, I researched existing products and assessed what current technology could support.

Post-Use Considerations

“As the design progressed, I began to think beyond making the product work. I started to consider how it feels to use, and what should happen when it is no longer needed.”

Prototype Overview

Working Process

When working out, if a muscle is used incorrectly or pushed too hard, the chest area of the garment vibrates to alert the user. This tells user something needs adjustment. The user can then check the app to see which muscle is involved and follow simple guidance to correct their movement.
