What is Glassfrog

Breakthrough Technology

Revealing human physiology today

Glassfrog’s approach to electrical-field sensing of features and movements inside the human body applies the well-established physics of electrical permittivity to biological systems at a hundred times the resolution of the state of the art today.

The molecules in your cells and tissues affect the electrical fields passing through your body everywhere you go. Static, hospital-sized, or biopsy-based equipment has been able to measure isolated characteristics of this electrical field interaction; however, they are limited in scope, resolution, and accessibility.

A future with MRI-level insight in every home

The most sophisticated diagnostic tool in existence is used on average once per decade per person because it is huge, loud, and expensive. What if you could achieve that level of insight every night for your whole life to better your health, your sleep, and your longevity?

From sleep, cardiac, and respiratory time series detail today, we are building to high resolution four-dimensional sensing tomorrow. Glassfrog is leading the new wave of physiological insight, and bringing it to everyone.

Raw data, AI insight

Correlating rich physiological signal

Powered by AI, Glassfrog is connecting novel physiological signatures to the fine detail of sleep, cardiac, respiratory health, and more.

Over time

Be understood in detail, over time

One night tells you little. A thousand nights of the same high-fidelity signal shows you what changes, what recovers, and what needs attention.

Every age

One technology, from the first night on

Glassfrog’s unique form factor and sensitivity mean we can provide uninterrupted, unparalleled health insight from birth to informed aging.

Seamlessly works in any environment

Integratable into life without behavior change. The sensor is flexible and can be separated from the skin by layers of textiles while still seeing deep physiological function.
