The Problem

Modern Life Is Overstimulating Your Nervous System

Chronic stress, disrupted sleep, and mental fatigue are not personal failures. They are physiological responses to an environment our nervous systems were never designed for.

77%
Report Physical Stress Symptoms
Regular physical manifestations of stress — fatigue, tension headaches, and muscular pain — affect the vast majority of working adults.
1 in 3
Adults Have Chronic Poor Sleep
Sleep disruption and insomnia are epidemic, directly degrading cognitive performance, immune function, and emotional regulation.

Lost in Productivity Annually
The economic burden of stress-related illness and reduced output represents one of the largest preventable health crises worldwide.

The vagus nerve and auricular nerve fields offer a direct, non-pharmaceutical pathway to modulate the autonomic nervous system. Until now, this technology has been locked inside clinical devices costing thousands of dollars — inaccessible to the people who need it most.

The Solution

Controller + Fibonacci Earpiece

A precision wearable stimulator paired with the Fibonacci Earpiece — a configurable ear-worn electrode assembly that brings clinical-grade auricular nerve stimulation into your daily routine.

Core Technology

Dual-Channel Architecture

Two independently programmable stimulation channels — the foundation of CoolStim's unique layered protocol capability.

CHANNEL A

Base Stimulation

Continuous, independently parameterized stimulation. Runs your selected program with configurable pulse rate, width, duty cycle, and intensity.

Pulse Rate: 5–90 Hz
Pulse Width: 100–500 μs
Intensity: 0.25–5 mA
Duty Cycle: Configurable
CHANNEL B

Burst Stimulation

On-demand burst program activated via wired or wireless burst button — wrist, ring, pendant, or inline control. Delivers burst while Channel A maintains base program.

Trigger: Burst button (wired/BLE)
Mode: On-demand overlay
Switching: Fast channel toggle
Safety: Impedance-gated
☈
Triple Safety Architecture
Hardware current limiting — firmware impedance and current monitoring — independent hardware watchdog timer. Three autonomous safety layers. Any single fault halts stimulation immediately. Designed to IEC 60601-1 medical electrical equipment standards.
Output Type
Current-controlled biphasic
Compliance Voltage
Up to 60V
