The EU introduced legislation requiring companies that make digital devices and software to fulfil cybersecurity requirements. As a result, the 3D customized TENG generated a significantly high output voltage and current of 880 V and 3.75 mA, respectively. Through the strain difference between the flexible and rigid parts at the contacting interface, the tribo-interface can generate additional lateral frictions as it is squeezed during foot stepping. The conformal 3D customized interface provided wear comfort, even tribo-contact per foot pressure, and more importantly, augmented tribo-effect from strain-mismatching friction. The overall device, targeted for use in shoe insoles, was ergonomically designed based on foot geometry and fabricated accordingly via 3D printing using flexible and rigid materials. The nanofiber-interfused tribo-surface notably enhanced the output performance via the charge-trapping effect, which minimized intrinsic losses in the triboelectric charges. Based on an electrospun ferroelectric poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) nanofiber mat, an interfusion with a charge-trapping layer was proposed to create an integrative negative tribo-interface component, in which a polydimethylsiloxane (PDMS) layer was partially interfused with a nanofibrous mat. We developed a high-performance triboelectric nanogenerator (TENG) synergistically integrated with three-dimensional customized interfaces. ![]()
