NUROSS · Vona
Vona is a gentle, non-invasive wearable that fits right into your evening. Ten quiet minutes. No gel, no mess — just press once and let the day fade back.
Ten minutes of gentle stimulation to help you step out of a busy day. (Design goal)
Skin-ready electrodes out of the box. No cleanup, no sticky residue.
Put it on, press the button, and your session starts. No figuring out settings, no fuss.
Lightweight neckband design. By minute two, you’ll stop noticing it’s on.
Years of work in ultrasound and neuromodulation. Transparent about what’s verified and what’s in design.
Rechargeable via USB-C. Keep it by the couch, take it on work trips.
Meetings, pings, context-switching. Coffee borrows energy from later — with interest. By 3 PM you’re staring at the screen, and the day still has half its to-do list left.
You don’t need more coffee. You need a reset.
Lights off, mind on. The day’s debrief plays on loop — that email you should’ve sent, that meeting that went sideways, tomorrow’s first call. The harder you try to wind down, the louder it gets.
You’re tired enough. Your mind isn’t.
Another red bar. Another “low recovery” notification. You know you slept badly — thanks for the news. Wearables are great at watching. What’s missing is the part where you can actually do something about it.
Stop scoring. Start changing.
There’s a better way to end the day.
Vona
Your ten-minute reset button.
Vona rests light on your neck and delivers gentle vagus nerve stimulation. The vagus nerve is your body’s built-in pathway for rest and digest — the state it reaches when it finally feels safe to slow down.
No surgery. No implants. No gel. Just one button, ten quiet minutes, and then you’re back to your evening.
Sensono
The companion that shows you what’s actually changing.
Sensono tucks behind your ear and takes about sixty seconds of quiet rest (design goal). It gives you heart rate and HRV — each reading comes with a quality flag, so you know when a number deserves your trust.
Check before your Vona session. Check again after. That’s how you see what, if anything, actually changed.
Sixty quiet seconds with Sensono. See where you stand.
Ten gentle minutes with Vona. Let the day go.
Read again. See what changed. Learn your rhythm.
From our early access program. Individual experiences vary.
“I tried it after a long day of back-to-back meetings. Ten minutes later, I actually felt like I could go home and enjoy my evening — not just crash.”
“The no-gel thing is huge for me. I’ve tried other devices and the mess is why I stopped. This I can actually see myself using every night.”
“I like that it doesn’t promise the world. It’s a tool — and for me, on the right nights, it makes a real difference.”
Science & trust
NUROSS comes out of years of work in ultrasound and neuromodulation. We don’t call things clinical until they are. We don’t promise results that aren’t backed by evidence.
What we do promise is this: we’ll tell you what’s verified, what’s in design, and what’s still in research. No marketing fluff. Just honest engineering.
No. Vona is a consumer electronics product. It is not intended to diagnose, treat, cure, or prevent any disease. If you have persistent sleep or health concerns, please see a doctor.
Individual experiences vary. Vona works with your body’s natural rest-and-digest pathway via vagus nerve stimulation. We’re transparent about what’s been verified and what’s still in design — and we’ll keep updating as we learn more.
Vona gently stimulates the vagus nerve — the pathway your body uses to switch into “rest and digest” mode. It’s the same system that kicks in after a good meal or a deep breath. We use a mild, non-invasive current to activate that pathway in about ten minutes. (Design goal)
No gel needed. The electrodes are skin-ready out of the box. Just put it on and press the button.
Wearables are great at tracking — they tell you how last night went. Vona is about doing something about tonight. It’s not a tracker — it’s a tool for when you want to actively step out of a long day.
If you have implanted medical devices, are pregnant, or have specific health conditions, consult your doctor before use. Full contraindications are in the user guide. When in doubt, ask your doctor.
