Wave energy supplying for wireless sensor nodes

With the purpose of solving the continuous supply of energy of wireless sensor network in the water environment, wave power is utilized for wireless sensor nodes. Based on mechanical movement principle and electromagnetic induction. This paper has designed two mini generator, namely gear device and pulley device. The electrical energy which mini generator generates puts aside the battery via AC-DC conversion circuit, then DC-DC conversion circuit is designed to attain supply voltage in demand for wireless sensor nodes. Experiment result shows that the mini power supply system can satisfy normal nodes, which provides one new method for supplying continuous supply of energy of wireless sensor network.
