The technology map
Seven fields, one signal path.
Seven application areas, each with different chemistry and a different question — and all of them running the same measurement chain underneath.
-
Immunoassay
Electrochemical immunoassay on a disposable electrode. Amplified redox chemistry pushes antigen detection toward the picomolar floor — read by the impedance chip, not a laboratory.
Literature -
Molecular Diagnosis
Photothermal PCR paper chips and cold-chain-free LAMP. Light-driven thermal cycling keeps amplification ultrafast without surrendering specificity — sample to answer in under 25 minutes.
Literature -
Glucose Measurement
One strip, two physics: DC electrochemistry reads glucose while an AC impedance sweep reads hematocrit — so every result is corrected for the blood it came from.
Design intent -
Wearable Sensors
Flexible, multichannel, skin-conformal sensing. Sweat chemistry, continuous ECG monitoring and phase-controlled neuro-stimulation on the same ultra-low-power front-end that drives BEAT Connected.
Literature -
Lab on a Chip
The whole assay in one sealed cartridge — extraction, amplification, detection — so contamination stays inside and the instrument shrinks below 250 grams.
Literature -
Idea to Product EDA
From specification to signed-off silicon and PCB in one automated open flow — timing closed, design rules clean, layout matching schematic, every gate re-run from source.
Tool verified -
Biometrics
TruePrint reads the signal others discard: ridge flow reconstructed from latent and overlapped fingerprints, fused with fundus and EEG into one identity platform.
Literature
Core competencies
Three layers, one signal path.
A measurement front-end small enough to disappear into a device, chemistry that turns biology into current, and models that recover meaning from noise.
Bio-Sensor
Electrochemical immunoassay, photothermal PCR and cold-chain-free LAMP — molecular diagnostics that leave the laboratory.
Literature Biosensor platformAI Analysis
TruePrint reconstructs ridges from latent fingerprints, separates overlapping layers, and fuses fundus and EEG signal into one platform.
Certified software AI platformThe bio-digital twin
From an electrode to a decision.
Every UCARETRON platform runs the same four steps. The difference between them is how much of it fits inside the device in your hand.
Sense
A disposable electrode turns an antigen–antibody binding event, or a temperature cycle, into current.
Biology Electrical signal
Sweep
The impedance chip sweeps 0.1 Hz to 200 kHz and records the complex response at every frequency.
0.1 Hz 200 kHz
Model
Fourier analysis moves the signal into the frequency domain, where equivalent-circuit structure becomes visible.
Time domain Frequency domain
Decide
Machine learning reads the non-linear shape of the spectrum — including phase — and returns a result.
Measurement Decision
Schematic of the shared measurement chain — not measured data
Product
BEAT Connected
A connected bio-electric platform for the nervous system. Heart-rate variability, nerve-conduction timing and a drawn trace go in; a model infers state; precisely phased stimulation across wirelessly synchronised nodes comes out — small enough to wear, precise enough to matter.
-
Closed loop. Stimulation as a response to a measurement — HRV-based anxiety prediction shapes a cranial stimulation pattern only when warranted.
-
Stereo, phase-controlled nodes. Multiple nodes, one wireless clock, deliberately different phases — no single pattern for the body to habituate to.
-
Nerve function as timing. Relative conduction time between two pathways, with the electrode-contact impedance factored out.
Design intent · public patent record
Low in the sweep the current cannot cross a cell membrane, so it reads the
extracellular space. Past the β-dispersion it does — the same electrode
pair, a different compartment.
Advance it until the two arrivals land together. The shift at that point
is the difference in conduction time.
The unknown. It is never measured directly — it falls out of the
matched shift and the known distance.
All on one wireless timebase — the phases between them are set, not drifting.
At zero every node pushes the same way. Open it and the resultant collapses
— which is the point: no one pattern for the body to habituate to.

Bio-Impedance Mapping is a concept, not a shipped feature. The other two are mechanisms
from the public patent record, drawn as designed — computed curves, not recordings.

How to read a claim on this site
Six labels, in order of how directly a claim touches reality. They are labels for the kind of fact, not a score — a peer-reviewed primary source and one of our own single measurements are different things, not better and worse ones.
- Physically verified
Confirmed on real hardware, in a real experiment, on a real sample.
- Tool verified
Re-executed and reproduced in design tooling — EDA, CAD, simulation.
- Published spec
An official published specification or public record, ours or an issuing body’s.
- Literature
Grounded in a peer-reviewed primary source with a DOI or PMID.
- Design intent
Our own design intent or proposal. Not yet measured.
- Illustrative
A drawing made to explain a concept. Never data.
