Sensor technology

Imagine unlocking the body’s internal signals, continuously and non‑invasively. Our technology transforms that from vision into reality.

The foundation is a wearable sensor platform that reads biomarkers, most notably lactate, through the skin. It uses advanced electromagnetic sensing to detect changes beneath the surface, tracking metabolic data that until now required blood draws. We measure how the body responds to exertion, stress, and recovery in real time, with clinical‑grade precision.

Because it can easily be built into a flexible, skin‑friendly wearable, the technology works across everyday wellness, elite sport and critical care; without needles, without disposable waste, without disruption. That means deeper insight becomes practical insight.

Why this matters now

It closes a data gap
Today’s wearables monitor heart rate, movement, oxygen, but rarely biological chemistry. Our system adds that missing layer: real biochemical context, live and continuous.

It’s scalable
Designed to fit into consumer wearables, athletic gear or hospital monitors, the platform scales from one user to millions with manufacturing‑ready architecture.

It’s built on evidence
Early trials show consistent lactate detection in real‑world conditions, on exercise, during recovery and through daily wear.

Respect for users and the planet
Skin‑safe, non‑invasive, and free of single‑use plastics and consumables. Durable and comfortable for stress, sweat or sleep.

What you get when you build your wearables with Sentinel

Continuous biomarker tracking
Live insight into physiology, not just surface metrics. Instant feedback. Better decisions.

Needle‑free, wearable comfort
Seamless integration into daily life or training, no disruption, no discomfort.

Robust and reproducible sensing
Reliable data quality that meets both consumer and clinical standards.

Modular, scalable architecture
Flexibility to embed into wearables, fitness gear or clinical devices, fast to market.

Sustainable design
No disposables, no ongoing waste; cheaper to run, kinder to the planet.

Looking to the future

Looking to
the future

We are actively refining the sensor platform, broadening the detectable biomarkers beyond lactate, and optimising for integration across multiple form factors, from smartwatch‑linked armbands to clinical monitoring systems. The goal is not just to invent but to deliver.

Multi-analyte potential
Lactate now; Oestrogen, Progesterone and Glucose to follow.
Sentinel's technology has been designed to be a multi-analyte monitoring platform. Non-invasive continuous lactate monitoring is validated and ready for commercialisation, blood glucose is in the test phase, whilst Oestrogen and Progesterone will follow for the female fertility market.

When you choose to build with this technology, you’re not buying a feature; you’re unlocking a new dimension of data. One that turns surface stats into biological sense.
