For researchers
Jaw behaviour data from the real world.
Most bruxism research still leans on self-report and single-night lab studies — while the behaviour varies night to night and lives at home. JawSense enables longitudinal, at-home jaw EMG monitoring with app-based momentary assessment: the objective field data the literature keeps asking for.
The platform
What the platform can do
01
The sensor — sleep and jaw activity, longitudinally, at home
- Two-channel EMG from both temporalis muscles, plus sleep, pulse and movement context
- Multi-night, multi-week protocols in the participant's own bed — the night-to-night variability single lab sessions miss
- No lab visits, no technician; participants run the protocol from their own phone
02
The closed loop — biofeedback you can customise
- Gentle cues delivered in response to jaw activity, during sleep and while awake
- Cueing parameters and closed-loop protocols customisable per study design
- Baseline, intervention and follow-up on one instrument — the same scale throughout
03
The app — trials with or without hardware
- Ecological momentary assessment, symptom diaries and check-ins on the same timeline as the physiology
- Customised self-management programmes and education modules for app-only study arms
- Built-in adherence and engagement tracking
Full raw data
Raw signals and processed metrics, exportable for your analysis pipeline — formats and access agreed per collaboration.
Consent-first, at scale
GDPR-compliant, explicit participant consent, anonymised exports — and N capped by recruitment, not lab capacity.
The data, on the participant's phone
One real night, on one timeline.
Cues along the top, jaw activity below — every episode placed across the night, scored the same way every night, with diary and check-in data on the same timeline. Raw signals and processed metrics are exportable in formats agreed per collaboration, and the participant runs the whole protocol from their own phone.
Study designs
What colleagues use it for
Prevalence & screening
Population-level, multi-night screening without the sleep-lab bottleneck.
Variability & longitudinal work
Night-to-night and week-to-week patterns, seasonal effects, response over time.
Intervention studies
Cueing and biofeedback protocols with built-in baseline and follow-up measurement.
Behavioural correlates
EMG alongside diary data — stress, sleep, caffeine, habits — on one timeline.
Track record
Funded by people who checked the technology first.
JawSense is funded by Innovate UK and the European Union, and built alongside university partners — five computer-science student projects with King's College London through the KEP programme, and multi-year research collaborations with Nottingham Trent University and York St John University.

Where at-home EMG sits in a study design
Not a replacement for either. A third option with a different set of trade-offs — read the questions on the left against your own protocol.
| Self-report & questionnaires | Lab polysomnography | At-home EMG with JawSense | |
|---|---|---|---|
| What it capturesThe behaviour, or a report of it? | A report, subject to recall and to being asleep at the time. | The behaviour, recorded to the reference standard. | The behaviour, from the same muscle group, in the participant's own bed. |
| Nights per participantHow much of the variance do you see? | Not applicable — one impression per instrument. | One or two, at cost. | Multi-night and multi-week, by design. |
| Where it happensHow ecologically valid is the setting? | Wherever they fill it in. | A sleep laboratory, wired, with a first-night effect. | Their own bed, their own routine, their own phone. |
| What caps your NWhat stops the study getting bigger? | Response rate. | Bed nights, technicians and the schedule. | Recruitment — not lab capacity. |
| Intervention armsCan one instrument deliver and measure? | No. | Not in the home. | Configurable cueing with baseline and follow-up on the same instrument. |
| What you may claimWhat is its regulatory standing? | Established instruments with known limits. | The reference standard. | A consumer wellness product, not a certified medical device. |
Reading the table: PSG wins on validity for a single night, and at-home EMG wins on how many nights you can afford to look at. Which matters more is a property of your question, not of the hardware. Methods and limits are published, and we will put the same caveats in writing for an ethics committee.
