The global electric consumption has been soaring due to over demands and an increase in social and individual costs. For that, scholars have researched various findings and they have been discussed to improve energy efficiency of electricity consumption. In this regard, the paper focuses on studying automatic doors which are set in every building in the world to improve energy efficiency. The demands of automatic doors have been annually soaring in the market of automation. However, it is hard for the doors to reduce energy consumption, due to higher switching frequency. Accordingly, the paper aims at energy-harvesting which transforms inertia kinetic energy into electric energy by sections of constant velocity and deceleration of automatic door. In particular, the paper focuses on sliding automatic door with window to regenerate and save electricity; the paper saves the energy of 7.2[W] in an experiment. Therefore, it is expected that the power will be used for secondary power source of safety sensors and contribute to save electronic consumption.
