Wearable sensors are under a rapid development in recent years with various sensing functions, principles, and formats. They can be widely used in many aspects of daily life and industry. This paper introduces various wearable electronic sensors and their typical measurement approaches based on a comprehensive review of the state-of-the-art commercial products and devices under exploration. The wearable sensors can be further categorized as the skin sensors, the indirect skin contact sensors, and the implantable sensors, as can be demonstrated by a large number of commercialized devices and laboratorial prototypes used in areas such as the daily health management, the healthcare, the sports science, the industry, and the military fields. This paper proposes a combination of the wearable sensing technology and the big data and the precision medicine for the long term dynamic information collection of both human bodies and environment. Highly integrated wearable sensors and the multi signal detection will be one of the future development trends for wearable sensors, but several challenges such as the energy supplies, the data security, and the establishment of the standards still require a further breakthrough. The development of the wearable sensor industry in China demands the support of the entire industrial chain. In completing the chain, wearable devices have important and persistent influence on the economic and social development in China.
