A $25 wrist-worn device that continuously monitors Parkinson's tremors using on-device AI — no smartphone, no WiFi, no infrastructure required.
Three steps from wrist to doctor's office — no apps, no cloud, no complexity.
An accelerometer and gyroscope sample hand movement 100 times per second, capturing the precise frequency and pattern of every motion throughout the day.
A compressed neural network running directly on the ESP32 microcontroller classifies each movement in real time — distinguishing Parkinson's tremor from normal activity without any internet connection.
Timestamped tremor events are written to a micro SD card. At the next clinic visit, the patient hands the doctor weeks of continuous real-world data instead of a five-minute observation.
We looked at every Parkinson's wearable on the market. Every single one requires a smartphone or WiFi. That means the patients who need monitoring most are the ones who can't use it.
$400+ device. Requires iPhone. Designed for fitness tracking, not Parkinson's monitoring. Useless without cellular or WiFi.
Thousands of dollars. Hospital-grade equipment that stays in the clinic. Patients go home with no monitoring whatsoever.
Bluetooth-dependent. Require a paired smartphone to function. Exclude rural patients, elderly patients, and low-income households entirely.
Built from the ground up for zero-infrastructure environments. The AI runs on the chip itself. The data stays on the card. The patient controls everything.
I'm a 10th grade student in Apex, North Carolina. I started TremoTrack after researching every existing Parkinson's wearable and finding the same blind spot in all of them — they all assumed the patient had a smartphone and reliable internet.
Most Parkinson's patients don't. So I built something that works for them instead.
TremoTrack is currently in active prototype development. The hardware is assembled, the sensor is communicating, and the AI model is in training. I'm working toward a functional proof-of-concept and plan to validate with local Parkinson's support groups in the Triangle area of NC.
