Feel the way
you want.
Sensa is an ear-worn system that reads your body’s signals and helps you shift into the state you choose — calm, sleep, focus, energy or recovery.
Restless → Calm · in minutes, not months of practice
Your mind is ready. But your body is still stuck in the past. Stress, brain fog, burnout and poor recovery come down to one thing — you’re not in the right state. Sensa is an easier way to get there.
Life moves forward. Your body needs to catch up.
Different pressures, the same result. The moments that matter most arrive before your body is ready for them.

“I am not in the right state.”
Stress, brain fog, burnout and poor recovery share one root. Sensa lets you move into the state you want — with less effort and no special setting.
Wearables show you the data. Sensa helps you act on it.
Sense
Ear-worn EEG and PPG read brain and pulse signals, combined with a quick note on how you feel.
Choose
Pick a target state. Sensa offers an informed suggestion — the choice is always yours.
Shift
Gentle ear stimulation and adaptive sound begin, with the change shown in real time.
Learn
Before-and-after signals and your feedback shape the next session.
Help your body meet the moment.
One body. A different state.
Sensa C / Connected.
A continuous ear cuff. Stimulation at the concha, sensing behind the ear, sound throughout — designed to disappear into your day.
EEG / PPG sensing
A rear module reads brain-activity references and pulse variability — combined with how you say you feel.
Ear stimulation + sound
Skin-contact electrodes at the concha deliver gentle stimulation, while sound supports regulation.
Made for everyday wear
One sculpted assembly. Comfort and stable contact come first, so it fits into real life.
One body. A different state.
Tell Sensa where you want to be. It responds within limits you control — and you can pause or stop at any moment.
Calm
More composure when it matters.
A short reset between high-pressure moments. Slower rhythms and softer sound help your body settle before the next thing.
Illustrative programs. Session lengths and intensities are planned and will be refined through user testing.
One simple choice. A better state of you.
From choosing a goal to sharing feedback, every step is designed to reduce effort. AI conversation is optional — a tap is always enough.
How do you want to feel?

Choose a goal.
Tap to choose. Add a few words only if you want to.
“That meeting was stressful. I need a break.”
Check in.
A short self-report combines with physiological signals. When signals are weak, Sensa says so — and offers a fixed program instead.
Begin.
Confirm the duration and a comfortable intensity. Reduce, pause or stop at any time — one tap, always.
Say whether it helped.
Did you feel closer to your goal? Was it comfortable? Your history informs the next session as adaptation is validated.
5–10min
One simple choice. A better state of you — designed to fit between the meeting and the moment that matters.
What you won’t need.
Planned interaction and duration, not established effects. AI conversation is always optional.
From seeing your state to shifting it.
Wearables help us see our body’s data. The next step is understanding it — and acting on it.
Categories summarize typical products in each group. ◐ partial support or external device required. All Sensa capabilities shown are in development and require controlled testing.
The ear is the interface.
One continuous cuff brings sensing, gentle stimulation and sound together — so shifting state takes minutes, not months of practice.
Everything in one continuous cuff.
Ear stimulation + sound
Skin-contact electrodes at the concha deliver gentle electrical stimulation to the auricular branch of the vagus nerve, while sound supports regulation. Each runs on its own control logic.
EEG / PPG sensing
A rear module reads brain-activity references (EEG) and pulse variability (PPG). Contact and motion are checked continuously — Sensa reports confidence, never forced conclusions.
One continuous form
A single sculpted assembly follows the helix. Form, weight, wiring and battery are designed for all-day wear — comfort and stable contact come first.
Three layers. One quiet system.
Hardware delivers the experience. A personal engine makes decisions. An optional AI conversation adds context.
03AI interface
OptionalUnderstands natural language, captures context and explains your signals clearly. Short tap-to-answer questions collect the same information without it.
02Personalization engine
Rules → learningUses signals, history and self-reports to suggest when to start, which program to use and how to adjust — within preset limits. Clear, explainable rules first; individual learning as evidence grows.
01Neuromodulation hardware
CoreEar-worn hardware delivers stimulation and sound. A local controller caps intensity, duration and rate of change, with weak-signal fallback and one-tap exit.
The AI talks. The controller decides.
Language models never directly control stimulation. The engine and local controller govern every parameter.
Physiological context
EEG, PPG and personal baselines. Contact quality and movement.
User input
Goal, time, feelings and preferences. Tap to respond; chat optional.
Signal processing & state estimation
Manage artifacts. Report confidence, not forced conclusions.
Personalization engine
Fixed programs first, personal adaptation next.
Local controller
Limits intensity, duration and adjustment rate.
Ear stimulation + sound
Delivered within the controller’s limits.
Before / after feedback
State and comfort feed the next session.
Science provides a foundation. Sensa must prove the rest.
Research supports ear sensing and ear stimulation separately. The direct test is whether stimulation plus sound outperforms sound alone — and whether personalization adds value.

Stimulation limits, EEG measurement and study protocols are reviewed with clinical advisors in neurology. Comfort and safety come before everything else.
One-tap stop
Reduce, pause or stop at any moment. Exiting is always a single tap — no confirmation, no delay.
Hard limits
A local controller caps intensity, duration and how fast anything can change — independent of software above it.
Weak-signal fallback
If contact or signal quality drops, Sensa tells you — and switches to a fixed, well-understood program.
