Wearable Sensors: The Heart of Health Monitoring
Wearable sensors are the backbone of modern health monitoring. Here are some key types of sensors and their applications:
- Heart Rate Monitors: These sensors use photoplethysmography (PPG) to measure heart rate and rhythm, providing valuable insights into cardiovascular health.
- Blood Pressure Monitors: Non-invasive blood pressure sensors use pulse transit time (PTT) or other technologies to monitor blood pressure continuously.
- Electrodermal Activity (EDA) Sensors: These sensors measure the electrical activity of the skin, which can indicate stress levels, emotional states, and other physiological responses.
- Accelerometers and Gyroscopes: These sensors track movement and activity levels, helping in the monitoring of physical activity and balance.
