Pulsetto for Research — Let’s grow the science behind nVNS together

Let’s grow the science behind nVNS together

Pulsetto is looking for researchers who want to find out what non-invasive vagus nerve stimulation can really do.

The vagus nerve sits underneath sleep, stress, pain and recovery — and the evidence base is still young. We would rather build it with you than claim it on our own.

01

What is Pulsetto

A non-invasive vagus nerve stimulation device worn on the neck. Bilateral cervical placement, programme durations set by protocol, built for repeated unsupervised use at home — which is what makes longitudinal and decentralised designs practical.

01

Bilateral cervical

Electrodes sit on both sides of the neck over the cervical vagus — a segment carrying afferent and efferent fibres, and roughly 5–6× more Aβ-fibres than the ear.

02

Home use, no supervision

Hands-free, no clinician present. Session length varies by programme. Adherence and dose delivered are logged in the app and exportable as an objective compliance measure.

03

Sham units exist

Identical in appearance and operation to the active device. This is the reason most investigators come to us rather than buying retail hardware.

Pulsetto is currently marketed as a general wellness product and is not intended to diagnose, treat, cure, or prevent any disease. Devices supplied under a research partnership are provided for research purposes only, and must be used solely within the scope of the approved study protocol.

02

How it works — the science behind the device

Stimulation reaches the cervical vagus through a distributed electric field, not direct electrode–nerve contact. The device pairs over Bluetooth with a dedicated phone app, where a set of distinct stimulation programmes can be selected and run. A protocol can therefore specify exactly which programme participants use and how often — and the app logs every session, so adherence is recorded rather than self-reported.

Bilateral placement over the approximate course of the cervical vagus. Vagal afferents terminate in the nucleus tractus solitarius; efferent output arises from the dorsal motor nucleus and nucleus ambiguus — cervical placement engages both directions.

Non-invasive VNS is rising in popularity as a research direction — many researchers in neuromodulation, and many doctors helping patients daily, believe that nVNS could be the future of autonomic regulation treatments. The device itself is deliberately undramatic: a collar worn on the neck, sending gentle pulses through the skin to reach the vagus nerve where it runs closest to the surface. No implant, no clinic visit, no needles.

Pulsetto was created from the desire to blend technology and neuroscience to help as many people live a lower-stress life. Help us create that future.

Pulsetto non-invasive cervical VNS: scientific background, study methods and findings

An educational overview of non-invasive cervical VNS: how the vagus nerve carries signals between body and brain, why fibre type and stimulation site change what a protocol can claim, where the field currently stands in research and regulation, and what our own pilot work found across symptom measures and stress biomarkers. Written for a scientific reader, and careful about the difference between what the evidence shows and what it merely suggests.

Science behind Pulsetto

The deck we walk investigators through on a first call. It covers what separates cervical from auricular stimulation, how we model the electric field the device produces in tissue, what our core studies have found so far, and where the regulatory work currently stands.

Published evidence

01

Acute transcutaneous cervical but not auricular vagus nerve stimulation increases alpha wave brain activity and lowers arterial blood pressure (2025)

Ahmed, Coello, Pillutla, Telwar, Stauss

Cervical — but not auricular — stimulation lowered systolic blood pressure (~134 → ~124 mmHg), with a trend toward increased frontal alpha. No heart rate change.

02

A randomized, open-label, parallel-group, comparative study designed to evaluate the use of Pulsetto for psychological stress, anxiety, and disturbed sleep in individuals (2026)

40 adults, four weeks, unilateral vs. bilateral. PHQ-9 −55.9%, GAD-7 −45.3%, PSQI −41.0%. Hair cortisol fell significantly with bilateral stimulation only. Not powered for efficacy.

03

Evaluating the efficacy of bilateral non-invasive vagus nerve stimulation in reducing migraine symptoms: a prospective observational study (2025)

Six weeks, observational. Migraine frequency −40.35% and pain intensity −42.46% (p < 0.001 both); pain days −27.66%.

04

Non-invasive vagus nerve stimulation (nVNS) for pain management in Bechterew disease (ankylosing spondylitis): a prospective open-label pilot study (2026)

Open-label pilot. Joint pain dropped significantly pre- to post-stimulation (p < 0.001); morning spinal stiffness and mobility improved in most participants.

05

Real-world longitudinal sleep changes associated with a wearable transcutaneous vagus nerve stimulation device: analysis of consumer data from the United States (2025)

Before–after analysis of wearable-derived sleep in users reaching 7–28 day streaks. Uncontrolled — useful for adherence patterns and effect direction when powering a trial.

What we offer researchers

Everything below is our in-kind contribution. You own the protocol, the data and the authorship.

Devices

1:1 active and sham device matching

Sham units are visually and operationally identical to active ones, so participants — and where your design requires it, assessors — cannot tell them apart. Quantity follows your power calculation, matched one to one for any blinded arm. A white-label version of the device is also available if your study calls for it.

Logistics

Hardware and shipping at no cost

Active and sham units free of charge. We handle international shipping, customs, and delivery to your site.

Data

Wearable integration

The app can pull alongside data from Oura, WHOOP, Apple Watch, Google Health and others, so HRV, sleep and recovery metrics can run as a secondary endpoint stream without you standing up separate infrastructure.

Dashboard

Research dashboard and data export

A dedicated dashboard lets your team watch participant data arrive as the study runs, rather than waiting until the end to find out whether adherence held. Everything is exportable — adherence, session timing, dose actually delivered — which doubles as an objective compliance measure.

Publication

Publication

We can support your publication process, and we particularly like working with early-career researchers. Worth raising when we first speak so we can work out what would be useful.

Study costs

Funding is worth raising early

Depending on the design and what we set out in the agreement, there may be scope to discuss a contribution toward study costs. Bring it up in the first conversation and we will tell you honestly what is and is not possible.

04

Sleep quality and insomnia
Stress and burnout
Anxiety and mood
Gut health and the gut–brain axis
Functional GI disorders
Migraine

Women’s health and dysmenorrhea
Perimenopause and menopause

How collaboration works

You own the science. We supply the hardware and the technical depth behind it. Five steps from first email to publication.

01

First conversation and test device

We talk through your study idea and the population you have in mind. We can also send you a device to try yourself before anything is decided.

02

Your protocol

You write and own it. We supply parameters, modelling data, and prior-study detail so your methods section is complete.

03

Your ethics route

You take it through your own IRB. We provide whatever device documentation, safety data, and technical files the committee asks for.

04

Devices on site

Matched active and sham units shipped free of charge, typically four weeks or more before screening opens. White-label units are an option too.

05

Publish, keep the credit

Authorship and publication rights remain yours.
