Wearable mechanical and electrochemical sensors for real-time health monitoring
Abstract
Abstract Wearable sensors provide a good solution for real-time monitoring of human health, and great progress has been made in miniaturization, flexibility, low power consumption and intelligence in recent years. Here, we introduce the principles of wearable sensors and their applications in disease surveillance. Physiological signals mainly include physical signals and biochemical signals. Among various sensors used to monitor physiological signals, we have introduced the basic working principles of mechanical sensors and electrochemical sensors. We summarize the examples of the clever integration of sensors with daily wearable products, and introduce cases of disease monitoring applied to the respiratory system, cardiovascular system, nervous system, musculoskeletal system and metabolic system. In view of the current situation of wearable sensors in terms of materials, structure, technology and energy, we discuss challenges and solutions of wearable mechanical and electrochemical sensors, and look forward to the application prospects of wearable sensors.
