With the rapid development of the Internet of Things technology and advances in micropackaging, wearable and portable electronic devices face new challenges related to battery replacement and charging. Energy harvesting technologies have emerged as promising solutions to these problems. Among them, triboelectric nanogenerators stand out due to their high-voltage output and simple, lightweight design. These features have stimulated considerable research on portable triboelectric nanogenerators (TENGs). Despite various advances in performance enhancement, more fundamental approaches are needed to address size-related limitations. In this study, we present a hybrid utilizing retrieving TENG (HUR-TENG), a body-coupled energy-integrated triboelectric nanogenerator designed to enhance the efficiency of portable TENGs by utilizing an additional energy source. The HUR-TENG harvests triboelectric energy generated in the contact and separation between the body and the ground, which is transferred via human body, harvesting conventional triboelectric energy from dielectric beads in the device simultaneously. This mechanism is applied to rope jumping and is optimized with various design parameters. The HUR-TENG efficiently harvests two energy sources to generate 59.98 μW of root-mean-square power and charges a 100 μF capacitor to 1.78 V, that is enough to power a commercial thermohygrometer.
