ENERGY STORAGE SELECTION METHOD FOR RF ENERGY HARVESTING WSN DEVICE

摘要

A method of selecting an energy storage in an RF energy transmission based WSN device is provided. A device according to an embodiment of the present invention allows energy to be stored in any one of a first storage and a second storage, in which energy is stored, and uses the stored energy to communicate with an external device. Therefore, a fast response can be performed in a low energy mode and a large amount of work can be performed in a high energy mode, so flexibility corresponding to situations can be secured through a trade-off between an amount of energy used and a response speed.
