In the field of energy harvesting and sensing technologies, triboelectric nanogenerators (TENGs) have emerged as a promising platform for self-powered sensors. However, user convenience is often overlooked during the material and design selection process. User-friendliness relies not only on material flexibility but also on the sensitivity of the force-to-signal relationship in TENG applications. This study aims to address this gap by tailoring material properties to enhance user experience specifically. We investigated the electrical and mechanical properties of various filler materials, utilizing styrene-ethylene-butylene-styrene (SEBS) as a stretchable polymer base. The resulting self-standing membranes were evaluated for comfort, durability, and adaptability, while maintaining functional effectiveness under low external force. These findings lay the groundwork for designing user-centric, self-powered sensing systems based on TENGs.
