Everyday Brain Care for Healthy Aging

Care for Your Brain
Before the Changes Become Obvious.

HERNOA turns everyday listening into an adaptive brain-care routine, combining personal audio, dual near-infrared light, biosignal sensing, and frequency-based sound to support cognitive vitality, relaxation, and sleep readiness.

Discover HERNOA See How It Works

Listen normally or choose a guided Focus, Relax, Sleep, or Brain Care routine. HERNOA senses your current state and coordinates light and sound within a personalized daily experience.

Verified Dual-Infrared Technology

Two Verified Near-Infrared Wavelengths, Delivered as Real Energy

HERNOA irradiates 800nm-class and 1000nm-class near-infrared light through HS FRAME™, its integrated photonic-semiconductor platform — supplying the energy your brain's mitochondria use to form ATP, and supporting healthy blood flow.

The glowing brain graphic is an illustrative visualization of the regions targeted by HERNOA's dual-wavelength light — not a real-time brain scan. EEG, temperature, and Blood-Flow Index sensing adapt the light and sound in real time; they do not image or diagnose the brain.

Why HERNOA

Brain Aging Affects Energy and Blood Flow — Quietly, Every Day

Supporting these factors directly has been difficult to access in daily life.

🧠

Hard-to-sense aging factors

Vascular function, the brain's ability to produce and use energy, sleep, stress response, and communication between brain regions all shift with age — but none of this is easy to notice or measure day to day.

⚡

Energy delivery stayed out of reach

Supplying enough near-infrared energy to support mitochondrial ATP production and blood flow has required bulky, high-heat equipment — not something practical to wear every day.

🧩

Daily management is fragmented

Personal audio, sensing, light-based care, and sound routines are typically separate devices and separate habits — easy to fall out of.

HERNOA integrates personal audio, biosignal sensing, verified dual-wavelength near-infrared energy delivery, and frequency-based sound into one repeatable platform for cognitive vitality, relaxation, sleep readiness, and daily brain care.

Who It's For

Built for Everyday Brain Health as You Age

Primary

Adults 55 and Older

HERNOA is designed primarily for adults aged 55 and older who want to maintain cognitive vitality, mental clarity, sleep quality, and daily brain performance as they age.

Secondary

Caregivers & Care Communities

Family caregivers, healthy-aging centers, senior-living communities, and wellness professionals seeking a practical, personalized brain-health platform for regular home or community use.

Two Devices in One

Not Just Headphones. Not Just a Therapy Device.

The same hardware supports two complementary forms of everyday use.

Every Day

Everyday Personal Audio

HERNOA works as a familiar over-ear headset — conventional listening, familiar ear-cushion comfort, and standard controls. No brain-care setup required.

On Demand

Guided Brain Care

Switch into Focus, Relax, Sleep, or Brain Care mode and the platform coordinates DNIR light, EEG and Blood-Flow Index sensing, and frequency-based sound — automatically.

Mechanism

Sense → Analyze → Adapt → Safeguard

A closed-loop adaptive controller behind every guided mode

📡

Sense

EEG, temperature, and Blood-Flow Index inputs are read in real time from sensors integrated into the headset.

Biosignal Sensing

🧮

Analyze

A proprietary closed-loop controller reads the biosignals against the Focus, Relax, Sleep, or Brain Care mode you selected.

Closed-Loop Control

💡

Adapt

DNIR light intensity and frequency-based sound routines are adjusted continuously — not a fixed cycle.

DNIR + Sound

🛡️

Safeguard

Independent hard thermal limits define the permissible operating envelope at all times.

Thermal Safety

Guided Modes

Focus. Relax. Sleep. Brain Care.

One headset, four goals — chosen by you, delivered adaptively

🎯

Focus

For students and professionals preparing for concentrated work.

🌿

Relax

For cognitive recovery after a demanding day.

🌙

Sleep

For winding down into a sleep-ready state.

🧠

Brain Care

For adults supporting healthy, everyday brain wellness routines.

DNIR — Dual Near-Infrared

800nm Band + 1000nm Band

Alternating emitters, paired with proprietary reflecting optics that shape a layered optical distribution

800nm Band

Cortical Targeting

Intended to interact with mitochondrial chromophores and support ATP-related energy metabolism around cortical regions.

1000nm Band

Deeper-Directed Distribution

Provides deeper-directed optical distribution associated with circulation- and oxygenation-related responses.

DNIR = Dual Near-Infrared. Research referenced here is exploratory and does not constitute medical claims.
