摘要
Entropy was first introduced in thermodynamics for describing the statistical behavior of molecules. In this paper, we use the entropy theory to describe the distribution and powering of small electronics in the era of internet of things. We refer the power transmitted from power plants to utility units as “ordered” energy for fixed sites, while refer the energy harvested from environment as “random” energy. Our conclusion is that the “ordered” energy is able to solve part of the power need for distributed electronics for IoTs, but the remaining part has to be supplied by the “random” energy harvested from our living environment using resources such as solar, vibration, motion and even thermal. The entropy idea defines the role played by energy harvesting as it will become increasingly important owing to the ever expanding usage of distributed electronics at the time of intelligence.
