| Popis: | This paper presents an energy harvester based on an improved eccentric rotor to generate electrical power from human body motion. An eccentric mass is suspended by a rotational spring to enhance the mechanical energy captured from low and random frequencies. An analytical model of the sprung eccentric rotor is developed to explore the power generation at a volume of 1 cm3. To compare with the conventional eccentric rotor, the sprung eccentric rotor was simulated with the real walking data measured from five different subjects. The sprung eccentric rotor generates double the average power output compared to the conventional one under optimal electrical damping and spring constant. |
