EVA / A WE-Sensing venture

A familiar pad. A new layer of health insight.

EVA is a smart menstrual sensing pad under development, designed to measure selected biological changes in menstrual fluid through a product women already use.

Development status

EVA is currently under development and is not available for clinical diagnosis or treatment decisions.

The need

Important biological changes remain invisible between clinical visits.

Wearable devices can reveal patterns in behavior and physiology, while clinical tests provide detailed information at individual moments. EVA is being developed to help capture selected biological changes during the time between those measurements.

Consumer wearables

Can help reveal behavioral and physiological patterns through indirect signals.

Clinical testing

Provides detailed information at individual moments under clinical direction.

EVA’s intended role

Explore longitudinal biological information between visits without replacing either approach.

Product design

Designed around a product women already know.

The EVA concept combines a disposable sensing pad, a detachable reader, and an application intended to organize measurements over time.

Smart Sensing Pad

A familiar disposable pad containing an integrated sensing region.

Reusable Reader

A detachable electronic device that captures and transfers sensor signals.

EVA Application

A secure interface intended to organize measurements and present longitudinal trends.

How it works

From routine use to a longitudinal view.

01
Use
The pad is worn as part of the user’s normal menstrual routine.
02
Sense
Integrated electrochemical sensors interact with menstrual fluid and generate electrical signals.
03
Interpret
The reusable reader and data-processing system organize and analyze the sensor response.
04
Understand
The application presents longitudinal trends intended to support future health understanding and clinical research.

Technology

Advanced sensing, integrated into a familiar form.

EVA extends WE-Sensing’s broader sensing platform into a women’s health application while keeping the physical product and user experience central to the system design.
