Check Your Health & Vital Signs From Your Face Using Photoplethysmography

Imagine a world where you could take a selfie and check your health at the same time! Thanks to Vastmindz, it’s now possible. We’ve developed a revolutionary technology that lets your camera check your health from your face using photoplethysmography (PPG).

In this blog post, we’ll explain what PPG is and how it works, the benefits of using Vastmindz’s technology, and the many potential applications of this ground breaking innovation. We’ll also answer some frequently asked questions about this topic.

What is Photoplethysmography (PPG)?

PPG is a non-invasive method of measuring blood flow and oxygen saturation in tissues. It’s commonly used in medical settings, such as hospitals, to monitor patients’ vital signs.

The technology works by shining a light through the skin and measuring the amount of light absorbed by the blood. When the heart pumps blood through the body, the volume of blood in the tissue changes, causing the amount of light absorbed to vary. This variation in light absorption is measured by a sensor and used to calculate blood flow and oxygen saturation levels.

How Does PPG Work?

Our technology uses the front-facing camera on your smartphone, laptop or tablet to take a video of your face. The video is processed in real-time using advanced algorithms that analyze the subtle changes in skin color caused by blood flow.

This allows us to extract PPG signals and calculate your vital signs, such as heart rate, oxygen saturation,and respiratory rate, without any physical contact or invasive procedures.
