Wearable sensors refer to electronic devices that are worn on the body to monitor physiological parameters, movement patterns, and environmental factors. These sensors are typically incorporated into clothing, accessories, or adhesive patches, allowing for continuous and non-invasive monitoring of various health indicators. Wearable sensors have gained popularity in recent years due to their potential to track and analyze data in real-time, providing valuable insights for applications in healthcare, sports performance, and daily activity tracking. This research area aims to improve the accuracy, reliability, and usability of wearable sensor technology for a wide range of applications.
