Why molecular monitoring?

A measurement captures a moment.
A trend reveals change.

Your body continually responds to movement, exertion and recovery. Individual readings capture only part of that story.

Repeated molecular measurements can show how selected biomarkers change over time. pheal aims to make this additional information accessible directly on the body.

The conclusions that can be drawn depend on the biomarker, the body fluid and the validated application.

01 / HEART

Reuse.

The rechargeable pheal Heart is the electronic core of the platform.

02 / SENSOR

Adapt.

Replaceable sensor layers determine which biomarkers are measured for each application.

03 / INSIGHTS

Understand trends.

Digital analysis is designed to bring measurements together and make changes easier to understand.

Which body fluids are planned?

We start with sweat. Looking ahead, we are developing access to interstitial fluid and capillary blood. Each extension requires its own development and validation.

Our perspective

Window into your body®

Our vision is to follow molecular changes directly in capillary blood in the future. Based on our patented technology, we are developing a minimally invasive access approach: a controlled superficial abrasion, approximately 1 mm in diameter, designed to make capillary blood accessible for continuous analysis.

From initial sweat-based applications to future medical solutions: we are expanding the platform step by step.

Medical Device

Planned from 2028

Up to 8 parameters in interstitial fluid (ISF).

Medical Device

Planned from 2030

Up to 8 parameters in capillary blood.

Exploratory development

Point-of-interest applications such as wound monitoring or incontinence monitoring — for targeted, continuous analysis of areas at risk.

Planned applications and development targets. Measurement performance and medical use require application-specific technical and clinical validation.

About pheal

Molecular sensing.
For life beyond the lab.

We bring together expertise in sensing, electronics and system integration. Our goal: turn molecular measurement principles into wearable applications that advance people's understanding and research.

How do we distinguish products from vision?

Research platforms, non-medical products and planned medical applications have different requirements. We identify each product line's development status and intended use separately.
