Abstract: Provided are an energy harvester using a mass, and a mobile device including the energy harvester. The energy harvester includes: a mass; first and second substrates spaced apart from each other, wherein one of the first and second substrates is connected to the mass; first and second electrodes provided on the first and second substrates; and an energy generator provided between the first and second electrodes, wherein the energy generator generates electric energy upon a relative movement between the first substrate and the second substrate caused by a movement of the mass.
