Abstract: In this research, the scientists are comparing the power harvested from two electromagnetic energy-harvesting systems. These systems are activated by human motion and utilize a combination of linear and nonlinear springs. The test results found that when the frequency was set at 1.5 Hz, the power output from both the real-life and computer simulation data was higher for the nonlinear system compared to the linear system. Finally, at 2.5 Hz, the power output for the nonlinear system was 62% higher for the real-life data and 68% higher for the simulation data compared to the linear system.
