英文摘要：

Energy limitation is one of main constraints to depress the network life time. However, network effective working hours can be extended by transforming the natural energy into the electric energy. Based on the analysis of characteristics of dry batteries and rechargeable batteries, by using combined power supply and energy management fuzzy control strategy, rechargeable sensor nodes suitable for low energy environment and the corresponding network platform are designed. The indoor and outdoor experiment validates that this design has a certain practical significance to solve the problem of energy limitation of wireless sensor network node.
