What we focus on
Non-invasive brain-computer interfaces and brain-health technology.
Non-invasive BCI · Brain health
Making sense of the brain
Synavelle connects brain science, artificial intelligence and engineering to move non-invasive brain-computer interfaces from research toward meaningful, real-world use.
Brain-sensing sleepbuds
Flagship · BCI-Sleepbuds
PSG-benchmarked EEG monitoring and adaptive sleep support
TWS sleep earbuds with a multi-channel ear-EEG signal array. Real-time brain data enables closed-loop, personalized sleep support while one compact device moves naturally from daytime listening to overnight use.
- Bean-shaped body nests inside the concha for pressure-free side sleeping
- Audio fades with detected sleep onset instead of following a preset playback duration
- Daytime TWS earbuds and overnight sleep monitoring in one device
01 · Our focus
From complex neural signals to trustworthy understanding
We are building a long-term technology foundation—not a single isolated feature. Our work focuses on reliable data, rigorous validation and responsible paths from research to real-world use.
What guides us
Clear evidence, scientific boundaries, privacy and ethical responsibility.
Human-centered questions
Start with real needs and the complexity of real people—not a technology looking for a use.
Reliable data first
Treat data quality, repeatability and individual differences as foundations for useful AI.
Progress with evidence
Advance through careful validation and communicate only what the evidence can support.
30s EEG sync interval for a low-latency closed loop
8h Continuous all-night EEG recording
5-stage W / N1 / N2 / N3 / REM sleep staging
2-in-1 Daytime TWS earbuds and overnight sleep support
02 · How we work
One trustworthy system for brain science, AI, and validation
Each layer supports the next: trustworthy inputs, rigorous evaluation, meaningful patterns and responsible interpretation.
- 01
Neural signal foundations
Researching non-invasive ways to capture and structure signals connected to brain activity.
- 02
Data quality & validation
Building repeatable methods to assess signal integrity before drawing conclusions.
- 03
Patterns over time
Studying longitudinal change and individual differences instead of relying on isolated measurements.
- 04
Responsible AI interpretation
Exploring explainable outputs that respect confidence, context and clear capability boundaries.
03 · Exploration areas
Technology with the potential to support better brain-health understanding
We explore possible applications carefully, without turning early research into premature promises.
Brain-health observation
Explore ways to make changes in brain-related patterns more visible and understandable.
Cognitive-state research
Study how attention, fatigue and recovery may be reflected in complex signals.
Longitudinal understanding
Investigate how stable data over time can provide more context than a single reading.
Research collaboration
Create useful tools and evidence with partners across brain science, AI and health innovation.
04 · R&D stage
Built through steady, verifiable progress
Current focus Functional prototype
The current program centers on technology development, repeatable validation and responsible product exploration for non-invasive brain-computer interfaces.
Functional prototypeIn-ear impedance ≈ 8.9 kΩSNR 18.46 dB
Detailed specifications and launch information will be shared after stage validation and intellectual-property planning.
