A Low-Cost Wearable for Tremor & Movement Monitoring
Turning an affordable motion sensor into objective, clinician-readable tremor data.
The Challenge
Tremor and movement disorders are often assessed subjectively — by visual rating scales that vary between clinicians and visits. Objective measurement exists, but the equipment is expensive, lab-bound, and impractical for routine follow-up or home monitoring.
The goal: capture reliable movement data using inexpensive, comfortable hardware, and present it in a way clinicians can actually use.
The Approach
- Frugal hardware — a wrist-worn inertial sensor built from low-cost, widely available components.
- Edge processing — on-device feature extraction (amplitude, frequency, regularity) so insight is available without the cloud.
- Clinician-readable output — clear summaries and trends instead of raw signal dumps.
- Comfort-first design — co-designed straps and enclosure so people actually wear it.
Testing & Validation
We evaluated reliability against reference measurements, comfort over extended wear, and how clearly clinicians could interpret the output — iterating on each before moving forward.
Outcome
A practical path to objective, repeatable tremor monitoring at a fraction of the cost of lab equipment — usable in the clinic and, eventually, at home.
Objective measurement shouldn't be a luxury reserved for specialist labs.
