Know Labs KnowU Device Inside Look

RF Dielectric Spectroscopy

Proprietary radiofrequency (RF) sensor measures glucose levels using dielectric spectroscopy by rapidly scanning a large range of RF frequencies.

It records voltage values detected at each frequency to quantify, with trade-secret machine learning algorithms, real-time continuous blood glucose levels.

The same techniques apply to a range of organic and inorganic materials to form the Know Labs spectroscopic technology platform. 

Blood Glucose is Our Priority

We are committed to making a difference in the lives of millions of people around the world.

Our journey begins with a focus on the nearly 550 million people living with Type 1 and Type 2 diabetes, and another 1 billion people with pre-diabetes.

Our Solution to Blood
Glucose Monitoring


No finger pricks nor continuously inserted transmitters


Proprietary machine learning algorithms manage and interpret large datasets to deliver accurate blood glucose values


No consumables & 

3x-5x less expensive

than current options


3D Data Improves
Clinical Accuracy

RF dielectric sensor safely sweeps through the full tissue stack (interstitial fluid, capillary blood, venous blood, cellular glucose) to a depth of over 10 mm to collect high-resolution voltage data at high speed, whereas the microneedle sensor in traditional CGMs measure interstitial fluid as a proxy for blood glucose

  • Antenna Array emits and captures radio wave signals, generates the “Energy Field” into 3D “Tissue Stack”

  • RF Generator enables frequency sweeps in the microwave spectrum, from 300 MHz to 4,400 MHz, at various intervals, 1.5M data points collected per hour.

  • Six key parameters, customizable with each sweep: power, frequency range, frequency step, dwell time, antenna permutations = >30,000 combinations.

Delivering High-Resolution Data

The RF sensor exploits the dielectric properties of glucose, including its ability to store electrical energy in an electrical field (known as permittivity) through a voltage reading received after broadcasting each frequency.
