TremET Band
Working toward objective tremor measurement between appointments.
TremET is an investigational device. It is not FDA cleared and is not available for sale.
Essential tremor is assessed in clinic, a few minutes at a time, on a scale read by eye. TremET Band is a slim, screenless wristband being developed to measure hand tremor through the day and to log each medication dose with a single press, so the picture between visits could be measured rather than recalled.
The problem
What happens between visits is largely unmeasured
Assessment is episodic
Tremor is rated during a visit that may last minutes, then not observed again for months. Day-to-day variability, medication response and fatigue effects fall outside the window.
Rating scales are observer-read
Clinical scales such as TETRAS depend on trained visual assessment. They are the accepted standard, and they carry inter-rater variability that instrumented measurement is intended to reduce.
Instrumented options are not routine
Quantitative tremor measurement exists, but most systems are specialised equipment that is not part of routine practice, so measurement between visits remains rare.
Approach
What TremET is being built to do
The system is in active development. The description below is of intended function. Performance has not been established, and no clinical performance claim is made or implied.
Wear
Worn, not operated
A screenless band with a six-axis motion sensor and an optical heart-rate sensor is designed to record hand and wrist motion passively through the day. There is nothing to hold and no task to perform.
Log
One press per dose
The wearer presses the face of the band once after taking a tremor medication, so each dose is time-stamped against the motion recorded around it.
Summarise
A daily summary and a between-visit report
A companion app is being developed to show the wearer a simple daily summary, and to give the clinician a report of how tremor changed across days and doses, for review at their discretion.
The band
What the band is designed to include
The sensing, radio, battery and feedback components sit in a single enclosed pod on a soft fabric strap, with no screen and nothing for the wearer to assemble. Component selection is still in progress. The specification below is a design target, not a production configuration.
- Sensing
- Six-axis inertial measurement unit (accelerometer and gyroscope); optical heart-rate sensor
- Input
- Press face on top of the pod, used to log a dose
- Feedback
- Indicator light and gentle vibration
- Link
- Bluetooth Low Energy to a companion app (iPhone; Android planned)
- Set-up
- Tap-to-pair with a phone over NFC (planned)
- Power
- Rechargeable cell; magnetic charger that clips to the side of the pod
- Form
- Screenless pod on a fabric strap. Design target 37 × 20 × 9.5 mm
Electronics
Electronics sized for the wrist
TremET's first instrument was a sensor pen. Every off-the-shelf development board was wider than the pen, so we laid out a custom circuit board to fit inside it. The band follows the same approach: the circuitry is being laid out for the wrist pod, rather than adapting a generic board, with a contract engineering partner.
- Sensing
- Inertial measurement unit; optical heart-rate sensor
- Radio
- Bluetooth Low Energy, antenna integrated
- Charging
- Magnetic contacts, on-board charge management
- Feedback
- Indicator light and vibration motor
The band electronics are in design. No band unit has been built.

Regulatory
Pursuing FDA 510(k) clearance
TremET is being developed toward a premarket notification under product code GYD. TremET has not been cleared by the FDA, and it may not be sold or promoted as safe or effective unless it is cleared.
We are not currently running a clinical investigation. No study is enrolling and no investigational results are available.

Progress
Where development stands
TremET is in active development. The steps below describe the current stage of work. No clinical study is underway.
Done: Pen prototype and custom circuit board
Our first instrument, a sensor pen, with a custom circuit board designed to fit inside it. The first assembled boards have been received. It shaped what the band needed to do.
Done: Band industrial design concept
External form, materials and controls for a slim, screenless wristband.
Active: Band prototype engineering
Electronics and enclosure for the first wearable prototypes, with a contract engineering partner.
Active: Bench testing
Verification of the assembled hardware and firmware on the bench.
Upcoming: Fit and sizing studies
Printed models worn on the wrist to settle size, strap and the position of the press face.
Upcoming: Planned pilot study
A study, subject to ethics review, to compare the band's measurements with clinician rating scales.
Upcoming: FDA Pre-Submission
Early feedback from FDA on the regulatory pathway.
TremET is an investigational device. It is not FDA cleared and is not available for sale.
How we got here
From a pen to a band
TremET began as a sensor pen, an instrument a patient would hold for a few minutes of guided writing tasks. Building it taught us how to fit sensing electronics into a very small enclosure, and it is where our patent filings began. In October 2026 we moved to a wristband, after feedback from investors favoured passive, all-day measurement over short tasks a patient has to remember to do. Work on the pen is paused.

Clinical and research enquiries
We are interested in speaking with movement-disorder clinicians and practice managers about measurement needs between appointments. This is a conversation about unmet need and study design — not a sales process, and not a solicitation of orders.
