Research Abstract

This research aims at realizing a new information infrastructure that allows sharing energy among sensor nodes as well as data. This system solves the energy supply problem that is considered as a barrier to penetrate wireless sensor networks. We have established a theory to design a resonator and match the impedance of the resonators. We also showed the performance of a modulation scheme that allows to send the data and power simultaneously.
