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.Electromagnetic generator | Hybrid generator | Portable power source | Slinky | Triboelectric generator[SDGs]SDG7journal article10.1016/j.cap.2023.02.0202-s2.0-85149738936https://api.elsevier.com/content/abstract/scopus_id/85149738936
