          With the rapid development of nanotechnology, electronic devices gradually miniaturization, multi-functional, low energy consumption direction. With a large number of communications, health monitoring, environmental monitoring and other multi-functional flexible electronic devices appear to facilitate people's daily lives. However, achieving continuous, long-term powering of numerous flexible electronic devices to form a flexible wearable self-sensing system is a challenge to existing power supply technologies. The energy consumption of a single device unit is as low as microwatts to milliwatts, but the quantity is huge and long-term working condition, so the total amount of electric energy needed to maintain its normal work is huge. The traditional battery can not meet the requirements of full flexibility of the system, The application of flexible wearable system. Flexible power supply is the key to achieve wearable self-sensing system. Energy harvesting and energy storage devices with bending, curling, stretching and other functions are essential elements of flexible power supply. Combining nanomaterials and new nanotechnology, it is of great research significance and application value to study the flexible power supply device that can be matched with various functional wearable sensor devices to realize long-term and stable operation of the self-driven sensor system.
In recent years, the Chinese Academy of Sciences Institute of Semiconductors, State Key Laboratory of Shen Jing Shen task group, wearable self-sensing system in the field made a series of progress. The energy devices currently used in self-driven systems are discussed: (1) Energy harvesting devices, mainly based on piezoelectric and frictional power generation, thermoelectric and solar cells; (2) Energy storage devices, including lithium batteries and supercapacitors; Comments on the design and development of an integrated wearable self-sensing system that integrates energy harvesting, storage and sensing applications. Research or research interests interested in wearable integrated systems play a leading role.
          The research work has been supported by the National Natural Science Foundation of China, the Natural Science Foundation of Beijing and the key research projects of CAS. Relevant research results published in the Small.
          If these products are put into production, smart wearable products and smart wearable manufacturers will be a major innovation. Will change the current market environment for smart wearable products to stimulate consumers' desire to purchase the products.
