Mobile Health Monitoring-Personal Health with Mobile Phones and rPPG Technology


The rapid development and widespread adoption of mobile technology have created new opportunities to revolutionize personal health management. One such opportunity is mobile health monitoring, which leverages smartphones and remote photoplethysmography (rPPG) technology to measure various physiological parameters. In this article, we delve deeper into rPPG technology and its applications, discuss the pioneering research led by Vastmindz in this field, and examine the benefits of mobile health monitoring for individuals and healthcare providers alike.

Remote Photoplethysmography (rPPG) Technology how rPPG Works

Remote photoplethysmography (rPPG) is a non-invasive optical technique that measures physiological parameters by analyzing the changes in skin color caused by pulsatile blood flow in blood vessels beneath the skin’s surface. A camera, such as a smartphone’s camera, captures these color changes and processes them to derive various health measurements. rPPG technology offers several advantages over traditional health monitoring methods which include

  • Non-invasive: rPPG is a contactless method, eliminating the need for uncomfortable or ntrusive sensors.
  • Ease of use: rPPG is user-friendly and requires no specialized knowledge or training for its operation.
  • Simultaneous measurements: rPPG can measure multiple physiological parameters at once, offering a comprehensive view of an individual’s health.
  • Cost-effective: rPPG utilizes readily available devices like smartphones and tablets, making it an affordable option for personal health monitoring.

Measurements You Can Read Using a Mobile Phone and rPPG Technology

By leveraging rPPG technology, mobile phones can measure several physiological parameters, including:

Heart Rate: rPPG can accurately measure an individual’s heart rate, providing valuable information on cardiovascular health and fitness levels.

Heart Rate Variability: rPPG can assess heart rate variability (HRV), which is the variation in time between successive heartbeats. HRV is a key indicator of overall health, stress, and autonomic nervous system function.

Blood Pressure: Through advanced algorithms, rPPG can estimate blood pressure non-invasively, allowing users to monitor hypertension and other related conditions.

Oxygen Saturation: rPPG can measure oxygen saturation (SpO2), which is the percentage of oxygen-saturated haemoglobin in the blood. SpO2 provides insights into respiratory health and can help detect conditions like sleep apnea or hypoxia.

Respiratory Rate: rPPG can estimate respiratory rate, the number of breaths taken per minute, which is essential for assessing respiratory health and identifying potential issues.

Stress Levels: By analyzing HRV and other related parameters, rPPG can provide insights into an individual’s stress levels, enabling users to make informed decisions about stress management and overall well-being.
