Design of High Performance Negligible Output Linear Generator Using Vibration Energy

To meet the changing needs of society, battery-free portable equipment is required. This paper reports the results of a study that investigated the construction of a generator in a pen. The goal of this research was to produce light in an LED over a long period by using less vibrational energy. A linear generator that produces electric energy from vibrational energy was examined. As a result of examining the coil dimensions of the linear generator, we found that it obtained 40% of the energy for our goal. In addition, we confirmed that 58.6% of the goal could be achieved when the number of coils was optimized, and when a pipe made of magnetic material was adopted.
