The sensor materials are the foundation of sensor technology. The development andapplication of new materials promoted the progress of the new sensors. The new application of conductive composite materials, composite nanomaterial, and carbon nanotubes materials were presented briefly in this paper on the multi-functions flexible tactile sensor, electrochemical biosensor, and semiconductor gas sensor. Sensor is one of the lead parts in measuring system that convert the input variables into measurable signal. It is an important part of the sensor system and a window responsible for information collection in the sensor system. Owing to the development of modern information technology andcomputer processing technology, the sensor technology research has improved greatly. Sensors play a more and more important role in modern industrial fields. Meanwhile, they also become a key component and essential lead unit in information collection system, automatic control system. Because of the rapid development of super large scale integrated circuit, the modern computer technology and communication technology's demand in accuracy, reliability, sensor response speed and obtain information is higher and higher, its low cost and easy to use also need to improve. The sensor material is the important foundation of the sensor technology and the development of new materials andapplication promote the development of the various kinds of new sensors.

This paper presents application of a CHB inverter based SESS. CHB inverter is characterized by cascade connection of multiple single-phase H-bridge (or full bridge) inverter cells. CHB inverter can make SESS flexible in circuit design, reduced voltage steps, and lower EMI. This paper presents circuit architecture design, modeling of CHB inverter based SESS, and control strategy focusing on power and energy balance control among Sub modules (SMs). The simulation results verify that the CHB inverter based SESS have a good performance in both fast power exchange and SM energy balance.
