A life in motion

Health has
no waiting
room.

Your heart, hearing and brain are part of one body. So are breathing, circulation and movement. Their relationships become more meaningful when we can follow your story over time.

A change in pulse takes on a different context alongside breathing, activity and your own history. Synseer’s developing Health Operating System is designed to connect these observations, so specialist AI agents can compare their findings and prepare a shared review for you and your clinicians.

The Health Operating System

The intelligence behind the devices.

The wearable is the collection point. The Health Operating System is the developing software platform that brings reliable data, a longitudinal personal profile, collaborative AI review and spoken coaching into one experience.

01 / Data worth building on

Sound-derived. Multimodal. Quality matters.

Designed around rich sound-derived waveforms, with optical, temperature, motion and applicable EEG adding other perspectives. Fit, timing, source and usable coverage determine which relationships can be examined.

02 / Relationships worth examining

Your history gives each signal context.

Compare change against your own baseline, connect patterns across body systems and bring specialist AI perspectives together. The aim is deeper insight, including predictive and early-detection capabilities that can be tested against defined outcomes.

03 / Insight worth understanding

Spoken into the ear. Clear enough to use.

Explain what changed, what is uncertain and a proportionate next step. The proposed experience lets the person choose a useful moment, answer the coach and review a summary before sharing it with their clinician.

More signals alone do not establish a better prediction. Synseer’s development path is to test whether their quality, relationships and longitudinal context improve a defined outcome, then validate the explanation and the intended use.

From evidence to an understandable next step

Hear how the finding becomes a conversation.

Sleep and heart · Simulated data
Proposed spoken experience

The same recordings should not lead to the same message when their quality differs. Try both examples. This illustrates the intended delivery logic, rather than a live prediction or alert service.

Comparable pattern

Nights in profile: 28
Recorded: 24
Comparable: 17

The evidence: Pulse and breathing changed together on four comparable nights. Seven other recordings were set aside because fit or context was unsuitable.
What it means here: A recurring observation deserves context. It does not establish a cause. Pulse and breathing share an underlying recording; home cuff readings have separate dates.
A proportionate next step: Invite the person’s context, review the dates and prepare questions for their clinician.

The Personal Health Profile

See which changes repeat.

Simulated example

Imagine someone who is already managing high blood pressure. A shared record of overnight pulse and breathing gives their care team the same dates to review, alongside symptoms and readings from a home blood pressure cuff.

Overnight readings

Compared with this person’s usual range on similar nights.

Illustrative overnight signals for one night in week three
Signal	One night in week 3
Overnight pulse Ear sensing concept	Above usual
Breathing variation Ear sensing concept	Above usual

Both signals changed on this night. Look across four weeks to see whether they changed together again.

Research question: Can combining signals flag a defined outcome earlier or more reliably than an individual signal?

Developing high-precision sensing

The unheard
side of health.

The profile starts with what we can measure at the ear. We’re developing sensing pathways for sound, light, motion and temperature. Fit and activity help us decide which readings belong together.

Complementary sensing. One personal profile.

Sound and light, together.

Four acoustic pathways can contribute different information. Optical sensing, temperature, movement and applicable EEG add complementary context. The Health Operating System is designed to keep their timing, source and quality together, rather than turn each reading into a separate story.

Four ways to listen

Infrasonic: Very low-frequency pressure changes in the sealed ear canal can carry information related to pulse and breathing.
Ultrasonic: Responses to controlled acoustic probes can help characterize the sensing environment and tissue-related behavior under investigation.
Otoacoustic emissions · OAE: The ear’s own acoustic responses offer a distinct pathway for ear-response characterization and identity-mapping research.
Ultra-high-frequency acoustics · UHF: Fine acoustic response detail is being explored as a complementary source of information about the ear and its listening characteristics.

More context for the same story

Optical · Light: Changes in reflected light can contribute pulse-wave information, alongside the acoustic record.
Temperature: Local temperature adds context to an observation and its collection conditions.
Motion: Activity, position and movement help distinguish a change in the person’s routine from a change in wear conditions.
Applicable EEG sensing: The HealthAids ear-loop development pathway explores electrical brain-signal information through behind-ear contact. It is not part of every product configuration.

Sensing contributions depend on configuration, usable coverage and product-specific validation. These pathways describe development work, not a set of released clinical measurements. EarPets follows a separate external-wear pediatric research pathway.

Read the narrated tour transcript

The human body is always speaking.

In every heartbeat, every breath, and every subtle change in circulation, there is information.

For generations, much of that information has been observed only in brief moments. During a visit. Through a test. Or after something has changed.

But the body does not wait for an appointment.

At Synseer, we believe the ear offers an extraordinary opportunity to listen more closely.

Close to the brain. Connected to the circulation. And uniquely positioned to sense sound, motion, temperature, and changes in blood flow.

Consider the brain.

Electrical activity can be detected through carefully positioned electrodes around the ear. Our research explores how these signals may contribute to understanding neurological and physiological patterns over time.

Now, the heart.

With every beat, the body produces pulses, motion, and acoustic activity. By studying these signals together, we can investigate how cardiovascular patterns appear at the ear.

And with every breath, pressure and circulation change.

Respiratory activity influences multiple signals. Combining carefully validated measurements may help us understand those patterns in greater context.

Throughout the body, blood moves continuously.

Optical sensors at the ear can capture pulse-related signals and changes in local perfusion. Each measurement is only one part of a much larger story.

That is where Synseer sees the real opportunity.

Not in a single number. Not in a single sensor.

But in the relationships between signals. How they change. How they interact. And what those patterns may reveal when interpreted responsibly, over time.

HealthBuds and HealthAids are being developed as platforms for ear-based health intelligence. Some capabilities are established sensing methods. Others remain in development and require further validation.

Our vision is to bring those signals together, help people understand meaningful changes, and make health information more continuous, connected, and useful.

Because the future of health intelligence is not simply collecting more data.

It is understanding what the data is telling us.

Sample evidence brief

Sleep and heart · Simulated data

Captured at the ear: Acoustic and motion signals with recording time, fit and activity context.
Derived from a signal: Pulse and breathing measures aligned by night and compared with the person’s usual range. Measures that share an underlying recording are identified as related.
Shared by the person: Home cuff readings and routine notes are shown with their own dates and sources.
Usable coverage: Of 28 nights in the sample, 24 have recordings and 17 are comparable. Seven recordings were set aside because fit or context was unsuitable.

A study question for partners Does adding breathing and activity context help reviewers interpret a recurring pulse change more consistently than pulse alone, when compared against an agreed clinical reference?
