How it works

Your tissues glow in the microwave band. We read the map.

Deep-tissue RF (microwave) passive emissions versus surface IR emissions

Capture the deep signal

Every tissue emits weak electromagnetic energy in the microwave band, set by its temperature and blood flow a few centimetres below the skin — deeper than any infrared camera can see.

Pair deep with surface

The probe reads deep microwave emission and surface temperature at 22 points, building a thermal field and the deep-to-surface gradient that carries the strongest ageing signal.

Compute the BioEnergy Index

Machine-learning models turn the field into a single BEI score (0–100) and an age-referenced BioAge estimate — a readout of how your metabolic, vascular and autonomic systems are tracking.

Repeat, and watch it move

Because it's non-invasive and takes minutes, you can measure as often as you like and see how sleep, training, diet and therapies shift your thermophysiology over time.

The evidence

Validated on 36,391 people — and it holds up against the clocks.

In a large-scale study published in Diagnostics (2026), thermophysiological features from MWR predicted chronological age at an accuracy comparable to first-generation epigenetic clocks — from a single, non-invasive measurement.

For the measure-everything generation

If you're optimising for a lower biological age, you need a signal you can read this often.

Epigenetic tests are powerful — but you can't run one every week. MWR gives the quantified-self and longevity community a deep-physiology readout that's fast, repeatable and painless enough to become a habit.

⌁

No needles, ever

Passive microwave sensing means no blood, no injection, no ionising radiation. Just place the probe and read.

↻

Measure as often as you train

A five-minute scan you can repeat weekly — the cadence you actually need to see whether a protocol is working.

◱

Deeper than a wearable

Wrist wearables read the surface. MWR reads centimetres into the tissue, where the metabolic and vascular ageing signal lives.

✎

See interventions move the needle

Because deep-tissue heat tracks mitochondrial, vascular and autonomic function, BEI is a natural readout for exercise, diet, sleep and therapeutic trials.

◈

One number, honestly derived

The BioEnergy Index is a single 0–100 score plus an age-referenced BioAge — learned from thermophysiology alone, never from your birthday.

⌂

Clinic-to-home roadmap

MWR2025 is available for programmes today; MWR2026 brings a clinical-grade, regulated version as approval completes.

Where the science stands Straight about what BEI is — and isn't

The BioEnergy Index is an age-referenced physiological measurement, not an outcome-validated clinical test. The 36,391-person study is cross-sectional and, at this stage, based on breast thermophysiology in women; extending to other body regions and to longitudinal, outcome-linked validation is ongoing work.

BEI should be read as a research and wellness signal for tracking change over time — not as a diagnosis of disease or a guaranteed predictor of lifespan. MWR2025 ships as a general wellness / research instrument. MWR2026 is a Class I medical device with documentation submitted for approval and is not yet cleared for clinical sale.
