Description

This study evaluates the peformances of an energy harvester prototype. The fabricated energy harvester comprises of a PDMS-based mechanical membrane and an electromagnetic component, designed to convert vibrational energy into low power electricity. The prototype was tested on three distinct vibrating machines: a Dynamic Rotor Machine, a motorcycle engine, and a Boeing 737-600 aircraft turbine. Vibrational frequency was measured using an FFT CF360A analyzer, while output voltage was recorded via a Hantek 20MHz 2-channel digital oscilloscope connected to a PC. The highest output voltage 0.989 Volt was achieved at 40 Hz (14,800 RPM) using the Dynamic Rotor Machine. In contrast, the aircraft turbine yielded significantly lower voltage (0.25 V) despite higher vibrational frequency (200 Hz). These results demonstrate the prototype’s efficacy in low-frequency environments and highlight its potential for applications in rotating machinery energy harvesting.
