Inside VAYU
Four tightly coupled technology layers.
Capture, sensing, correction and interpretation are designed as one measurement system, not as interchangeable add-ons.
- 01
Capture
Standardise breath fraction, flow, humidity and sampling conditions.
- 02
Sense
Measure a volatile pattern instead of relying on one convenient molecule.
- 03
Correct
Separate biology from ambient, oral, airway and instrument effects.
- 04
Interpret
Answer one predefined question with confidence and uncertainty visible.
Signal architecture
From controlled sample to reference-linked output.
One pulse travels through the product stack, carrying sample context into the final research output.

Source intelligence
The model must separate biology from its surroundings.
Ambient air, oral and airway chemistry, systemic metabolism, humidity and sensor drift can all shape the observed pattern. VAYU is being designed to retain and correct for that context.
Observed breath=ambient+oral+airway+systemic / gut+error
Illustrative source layerNot patient data
Which volatile products crossed into blood and reached the lungs?
Control strategy
Predefined targets, paired reference assays and confounder models
Initial research question
Can a defined gut microbial function or gut-lung phenotype be estimated reproducibly from controlled breath signatures?
The first validation protocol will lock one endpoint, one reference method and one target cohort before model development.
VAYU is not intended to reconstruct the complete microbiome from breath.
Platform assets in development
Four assets intended to compound together.
The device, calibration system, source-aware intelligence and paired data are designed as one evolving platform.
- 01Physical system
Controlled sampling
Breath fraction, flow, humidity, cartridge and collection quality.
- 02Instrument system
Sensing + calibration
Multi-channel response, interferent handling, blanks and drift correction.
- 03Intelligence system
Source-aware models
Ambient, oral, airway, systemic and device contributions retained in context.
- 04Accumulating asset
Reference-linked data
Paired breath, biological and clinical measures under consistent protocols.
Product expansion architecture
A common measurement core. Distinct clinical products.
Lung oncology
Test whether controlled, repeated breath patterns could eventually add an earlier signal and support response or recurrence research alongside established diagnostics.
Gut-brain and cognition
Study microbial function, metabolism and cognition using distinct biomarkers and cohorts.
VAYU does not currently diagnose cancer, predict COPD exacerbations, assess dementia risk or provide a complete gut microbiome test. Each intended use requires its own reference method, dataset and validation pathway.
