The Science behind FRENZ™ Brainband

Deep sleep. Deep focus. Deep relaxation.

With FRENZ™, we take science closer to our everyday life.

Precisely track brainwaves and bio-vital signals

FRENZ™ provides users with complete information regarding EEG signals with accuracy comparable to hospital-grade PSG-standard devices.

The human brain is an electrochemical organ. The electrical activity of the brain is shown through brain waves. There are five waves, delta, theta, alpha, beta, and gamma, from least to most active.

DELTA WAVES are the slowest brainwave. 

THETA WAVES are linked to creativity, intuition, daydreaming, memory, and emotion storage.

ALPHA WAVES - A person who just finished and started to relax is in the alpha state. 

BETA WAVES Activating beta waves help improve mental states and improve health. 

GAMMA waves help clear the mind and improve focus. *

Vital bio-signs are essential in assessing a person's physiological conditions and health monitoring. FRENZ™ enables the monitoring of PPG -  Measurement of heart rate and measure oxygen concentration inside the body (SpO2).

Real-time brain stimulation

Precision is the determinative factor for enabling advanced technologies to achieve high performance for FRENZ™.

Our technology takes advantage of real-time data processing and precise identification of bio-vital signals, then applies our proprietary AI/ML algorithms to stimulate better sleep, focus, and relaxation based on each individual's response.

For sleep, we have special algorithms that accelerate sleep onset and facilitate deep sleep based on real-time brainwave resonance stimulation. The precisely tracked phase-locked loop is the core strategy that helps us to deliver the acoustic stimuli adjusting to the physiological changes of the brain and body in real-time. 

For focus, our algorithms identify the ratio variability of beta waves versus alpha waves and other waves to track in real-time the focus score of the user. FRENZ™ will then curate the audio content that enhances the users' focus level.

For relaxation, our algorithms identify the ratio variability of alpha waves versus other brainwaves to track the relaxation score of the user in real-time. FRENZ™  then curates the audio content to soothe and calm the users' minds.

Insights at your fingertips

All your sleep, focus, and relaxation sessions are summarized with easy-to-read charts and statistics. By applying this data, FRENZ™ provides personalized coaching tailored specifically to you. Hence, the longer you use the device, the better the algorithms get, improving results.

 

Our sleep score is a weighted metric calculated by combining:

● Sleep efficiency

● Total sleep time

● Sleep onset latency

● Number of awakenings

● Deep sleep time

The SCI (Sleep Coaching & Insight) helps users achieve better sleep through coaching sessions that improve sleep hygiene and habit. All SCI suggestions are curated from clinically-proven papers and recommended by Dr. Robin R. Deterding - the Co-founder of Now Vitals.

Here’s our secret sauce

These three ingredients set us apart

FRENZ Touch™

FRENZ Touch™ is a patented material science breakthrough that precisely captures brain signals and the micro-signals of facial muscles and eye movements.

FRENZ Touch™ is strategically placed at the most optimal locations (over the ears’ area) to track and reference strong signal sources amidst the noise. 

FRENZ Touch™ is made of a proprietary perfect-ratio mixture of nanomaterials, including carbon nanotubes, silver nanowires, and conductive silicon, under a unique curing process that have super conduction while maintaining comfort in any sleeping position.

EE and ML algorithm

The mechanical engineering team and electrical-circuit experts engineered a proprietary low-noise electrical integrated system that captures signals precisely, eliminating noise caused by the wearer's movements. EEG, EOG, and EMG are extracted from the raw signals with an accuracy of at least 88% similarity (correlation coefficients and signal-to-noise ratio) to PSG data extraction.

Each signal piece is pre-filtered at the sensor level before it is cleaned, processed, and analyzed to ensure accurate inputs for specific features. The signals will experience through 2 layers of "filters" to ensure high-quality signal levels.

FRENZ™ developed more than 30 ML algorithms that enable clearer signal identifications, better separation of signals, precise signal detection, and effective and non-invasive sleep, focus, and relaxation stimulation.

Bone conduction audio

The FRENZ™ brainband integrates behind-the-ear bone conduction speakers in our innovative sound chambers to withstand head pressure and avoid sound distortion under any sleeping position.

Coupled with our real-time brainwave tracking, bone conduction is the non-invasive method of sending sound vibrations along the bones to guide the wearer into better sleep, focus, and relaxation. The audio content is curated from an extensive library of soothing words, music, and noise signals.

Testimonials

NGUYEN NGOC NHU THAO

Conservationist

I have a hard time falling asleep. I joined Earable® Neuroscience sleep lab to find a solution to my problem. FRENZ™ really helped me fall asleep faster and spend less time in bed. I can feel it takes me 20 minutes less than usual to sleep. I felt refreshed and full of energy the morning after. I will buy it for sure.

HA CAO

Triathlete

I used FRENZ’s pilot version for 2 weeks. Compared to other sleep tracking devices, FRENZ is a comprehensive device for sleep quality monitoring . After one week of usage, the device's insights helped me understand the factors and elements impact on my sleep health and offer me useful recommendations to improve my sleep quality. I definitely look forward to FRENZ's final commercial version.

ZEAN VO

Forbes 30 Under 30 Asia 2020, Founder of Makeitvietnam

Like many other older people, my parents find it hard to fall asleep. So I was trying to find a way to help them have a better sleep and monitor their health from afar. FRENZ became a trusted device for us after just one week of use. This home device helps them sleep better. They both enjoy using it for sleep, listening to music, and relaxing the mind. I can even track and manage their health when living far from them.
