How it works

Three simple steps: Detect. Decode, Deliver

1) Detect

Smart sensing of stress physiology uses devices to track how the body responds to stress, helping with early detection and better management

2) Decode

On-device AI decodes your stress signals in real time, offering instant insights and personalized support.

3) Deliver

Adaptive Vagus Nerve Electrical Stimulation (tVNS) delivers targeted impulses based on your body’s needs, helping to regulate stress, mood, and overall nervous system balance.

What Experts say about SerenSync

What impresses me about SerenSync is its ability to adapt stimulation in real time using individual biometrics. It reflects where neurotechnology is headed, toward personalization and autonomy. For anyone interested in cutting-edge, evidence-informed stress regulation, this is worth exploring

SerenSync bridges a major gap in wellness tech. Instead of just tracking stress, it actively supports regulation through closed-loop vagus nerve stimulation. The concept is grounded in strong science, and early users have a unique chance to help shape how this new category evolves.
Manuel. RastinDigital Health Consultant🇩🇪

Stress, poor sleep, and cognitive fatigue are deeply connected. SerenSync addresses them not through monitoring alone, but through real-time physiological intervention. It’s rare to see this level of integration in a wearable. Early access could offer meaningful insights for both users and the field

The Vagus Nerve

The vagus nerve — your body’s ultimate power line — connects your brain to nearly every major organ, earning its name from the Latin word for “wandering” as it weaves through your entire system.
Your body’s vagus nerve is the vital switch that calms your system, releasing serotonin and acetylcholine to soothe panic and restore natural balance — the way your body was designed to heal.

Stimulating the vagus nerve is backed by decades of research in neuroscience (read here for more details)

What Is SerenSync, And How Does It Work?
SerenSync is an AI-powered, non-invasive wellness device designed to support stress relief, mental clarity, and better sleep through personalized vagus nerve stimulation. It delivers gentle electrical pulses to the auricular branch of the vagus nerve via the ear, dynamically adjusted in real time based on your biometrics (like HRV). Our closed-loop system continuously adapts to your body, helping restore balance without user input. No guesswork—just science-backed calm.
No. SerenSync is designed for ease of use. Simply wear it as instructed, and the device will automatically adapt stimulation to your needs using built in sensors and the companion app. You don’t need any medical or technical background.
Basic features are available without a subscription. However, premium plans unlock advanced insights, extended analytics, and early access to new features. Early access users receive complimentary access to all premium features during the beta phase.
Yes. SerenSync uses low-intensity, non-invasive stimulation backed by scientific research and developed in consultation with experts in neurotechnology and physiology. The system continuously monitors and adjusts output to stay within safe limits.
SerenSync is intended for general wellness. It may help reduce stress, improve sleep quality, enhance focus, and promote a sense of calm. While not a medical device, it’s built on principles supported by peer-reviewed research in vagus nerve stimulation.
You can start, stop, and monitor sessions using the SerenSync mobile app. The device also features automatic mode: it adapts stimulation based on your real-time biometrics without requiring constant app use.
Absolutely. SerenSync is designed for regular use. Most users benefit from short daily sessions, and the AI adapts to your usage patterns over time to optimize effectiveness
