How It Works

Stress starts in the body. Zeno 1 starts there too.

Your nervous system constantly monitors for safety or threat. These signals appear in your heart rate, breathing, and muscle tension — often before conscious awareness. Zeno 1 detects these early indicators and responds automatically.

STEP 1

Advanced Physiological Sensing

Zeno 1 employs scientifically validated sensors to continuously read your body's physiological state:

Heart Rate & HRV

Photoplethysmography (PPG) technology tracks heart rate variability, a key indicator of nervous system balance.

Skin Conductance

Electrodermal activity (EDA) sensors detect sympathetic nervous system activation through micro-sweat responses.

Motion & Respiration

3-axis accelerometer captures movement patterns and breathing rhythms for comprehensive context.

These inputs provide an early, objective window into your stress response — detecting changes often before you feel them.

STEP 2

Intelligent Signal Processing

Raw biological signals contain noise and artifacts. Zeno 1's onboard algorithms ensure accuracy:

Signal Cleaning & Normalization

Filter and standardize data across multiple time windows to remove artifacts and baseline drift.

Feature Extraction

Extract critical metrics including HRV patterns, breathing cadence, and electrodermal activity spikes.

Contextual Analysis

Incorporate movement data to minimize false positives and improve detection accuracy.

Result: A reliable physiological snapshot updated every few seconds.

STEP 3

Embedded AI Recognition

A lightweight neural network, trained on curated physiological datasets, continuously evaluates your stress state:

Detection Criteria

HRV drops below personal baseline
Stress-related features spike simultaneously
Nervous system shifts into fight-or-flight

Key Advantages

  • • Runs locally on device — no cloud dependency
  • • Sub-second decision making
  • • Continuously learning your patterns
  • • Privacy-first architecture
STEP 4

Instant Automatic Response

When stress is detected, Zeno 1 doesn't just alert you — it actively intervenes:

Precision Haptic Intervention

A precisely controlled vibration is delivered via the DRV2605 haptic driver along the vagus nerve pathway in your wrist. This gentle stimulation helps activate your parasympathetic nervous system, naturally shifting your body back to a calm, balanced state.

Think of it as a biological circuit breaker — restoring balance without conscious effort.

Continuous Learning & Insights

Because Zeno 1 continuously senses and learns, you gain valuable insights without interrupting your day:

Real-time Awareness

Understand your nervous system state as it changes throughout the day

Personal Triggers

Discover what environments and situations affect your stress levels most

Pattern Recognition

Correlate daily habits with physiological trends for deeper understanding
