Abstract
Researchers are attempting to develop hybrid generators by integrating several mechanical energy harvesting techniques, although most of them employ complicated device structures and fabrication methods. In this paper, we propose a slinky inspired triboelectric-electromagnetic hybrid generator (S-TEHG) that can easily function as a portable power source for devices used in daily life. This S-TEHG generates a high output using a peak voltage and current output of up to 7.4 V and 83.2 mA, respectively. For practical application as a portable power source in everyday life, the S-TEHG is enclosed (packaged) in an acrylic cylinder. In this study, upon hand waving, the proposed packaged S-TEHG successfully illuminated an array of 15 light-emitting diodes and charged a 47 μF capacitor.
