BioBand

Complete Fitness Tracking Wearable with Heart Rate, Motion, and AI -- Integrated with MyFitnessTech

The breadboard prototype is up and running with biometric and motion sensors, and we've started bringing it to life on protoboard. Active build picks back up at the fall quarter kickoff in October. Goal: a working protoboard prototype paired with MyFitnessTech by the start of 2027.

What it Does

  • Tracks heart rate & blood oxygen with biometric sensors
  • Counts reps automatically with motion tracking
  • Detects exercise type (push-ups, squats, bicep curls)
  • Streams real-time data into the MyFitnessTech app
  • Pairs with MyFitnessTech for AI-powered workout coaching
  • Stores workout history with cloud sync

SipSync

Automatic Water Consumption Tracking with Smart Hydration Insights -- Integrated with MyFitnessTech

We just wrapped up the protoboard prototype with flow sensing and temperature reads. Next stop is the bottle-mount enclosure and MyFitnessTech integration when fall quarter kicks off in October. Goal: a full working prototype with smart hydration insights by the start of 2027.

What it Does

  • Automatically tracks water intake throughout the day
  • Syncs hydration data to the MyFitnessTech mobile app
  • Adjusts daily hydration goals based on activity level
  • Factors in body weight, weather, and exercise intensity
  • Sends smart reminders when you're falling behind on intake
  • Visualizes hydration trends and patterns over time

Tech Stack

Hardware

  • Flow sensor for volume measurement
  • ESP32 microcontroller
  • Temperature sensor
  • Rechargeable LiPo battery
  • Bottle-mount enclosure (3D printed)

Software

  • MyFitnessTech app integration
  • Bluetooth LE data sync
  • Hydration algorithm (weight, activity, climate)
  • Cloud-synced hydration history

Smart Hydration Factors

SipSync doesn't just count ounces -- it considers the full picture to personalize your hydration targets

⚖

Activity Level

Pulls workout data from BioBand and MyFitnessTech to increase hydration goals on active days

☁

Weather & Climate

Uses local weather data to adjust for temperature and humidity, so you drink more when conditions demand it

⚙

Body Metrics

Accounts for body weight and personal profile to calculate a baseline daily water target unique to you

🕐

Time-of-Day Pacing

Distributes intake goals across your waking hours and sends nudges if you're falling behind schedule
