| Summary: | The system for collecting wasted energy and converted into electrical energy is called an energy harvesting system. This paper focuses on the application of a boost converter to harvest leg muscle energy using a permanent magnet generator. A permanent magnet generator is a medium to convert the energy wasted from the leg muscles due to leg movements into electrical energy. The voltage result reaches 1.7Vac with a total 100 steps in 3 minutes. The output voltage generated by the permanent magnet generator is low-voltage with AC current. Therefore, there are stages of designing a rectifier and boost converter circuit in the self-power generation system. The output voltage generated from the rectifier and boost converter circuit is 5 Vdc. The 5Vdc output voltage will be supplied to the supercapacitor for storage. The supercapacitor charging takes ± 1 hour 25 minutes to full. The distance required to fully charging the supercapacitor reaches 5,500 steps on an average of 4.18 Km. Electrical energy stored in supercapacitors can be used by electronic devices such as sensors, IoT, and others. © 2023 IEEE.
