MEDDI BioScan

Indicative remote measurement of the state of health using the MEDDI application and the front or main camera of a smartphone - i.e. using digital photoplethysmography. This measurement is not intended to diagnose, treat, or prevent any disease and is primarily intended for personal use.

Measurement of health status

In about one minute

In about one minute, you can measure blood pressure, heart rate, heart rate variability (SDNN and/or RRi raw data), oxygen saturation, respiratory rate, sympathetic tone, parasympathetic activity, and pulse-respiratory quotient. All analysis is performed directly on the device.

New feature of the app

How does MEDDI BioScan work?

MEDDI BioScan is an integrated algorithm in the MEDDI app that extracts health measurements from a continuous video image of exposed skin on the surface of the human face with the help of hardware already built into the phone. The image is analyzed using advanced artificial intelligence and deep learning algorithms, including computer vision and signal processing technology. The measurement results will be displayed immediately after the measurement.

Safe and comfortable

Digital photoplethysmography

For non-contact data acquisition, the technology in MEDDI BioScan uses rPPG (remote photoplethysmographic imaging). rPPG is a camera-based solution for non-contact cardiovascular monitoring that has been shown to be as accurate as traditional PPG devices. The technology used in MEDDI BioScan measures changes in red, green and blue light reflected from the skin and quantifies the contrast between specular and diffuse reflection.

Backup contact solution

Contact PPG

For phones with a worse front camera, or in poor light conditions, MEDDI BioScan uses the technology of a backup contact solution. The contact-based solution acquires a PPG signal when users place their finger on the smartphone's rear camera. MEDDI BioScan automatically recognizes when conditions are not ideal for non-contact rPPG extraction and suggests the use of extraction based on contact with the smartphone's main camera

The MEDDI BioScan function is not a medical device according to current legislation. It is not intended to diagnose, treat or prevent any disease. The measurements obtained using the MEDDI BioScan function are only indicative and the measurement results are intended for personal use only. It is a module for measuring body functions using the photoplethysmography method via the front or back camera of a smartphone.
