An Overview of Wearable Flexible Sensors and its Applications

The important usage of wearable sensors is observing people’s physiological parameters such as body movements, movement patterns like walking, running, lifting, breathing observation, heart rate, cardiovascular signals, etc. Electronic skins are another set of sensors designed to act as normal skins. Some of these skins have the ability to measure pressure, temperature, strain and the ability to repair. Electrochemical sensing is the most commonly known flexible wearable sensing, and pressure sensors are the most standard usage of flexible wearable sensors. Using single-walled Carbon nanotubes as electrodes and Polydimethylsiloxane as substrate of a pressure or strain sensor, helps improve their performance. Measuring the breath duration, mobility, heart rate, etc. is performed using pressure sensors. Wearable flexible sensors also range from human health and environment analysis to smart robots which use them in order to have the same effect as the human body on the environment around them. Wireless physiological management system is commonly known as the transmitter of physiological sensing data from medical sensors to the processing unit (in real time). Wireless body sensor networks are divided into four levels: the system layer, the application layer, the sensor group layer, and the sensor layer, and at last, Bluetooth is recognized as the most optimal data transfer system in healthcare.Wearable flexible sensors range from human health and environment analysis to smart robots which use them in order to have the same effect as the human body on the environment around them
