A triboelectric nanogenerator (TENG) holds significant potential as a self-powered pressure sensor due to its ability convert mechanical energy into electrical energy. The output voltage of TENG is directly correlated with the applied pressure, making it highly suitable for sensing applications. Among key factors influencing performance, microstructure on surface plays crucial role. However, effect charge transfer behavior remains relatively underexplored. Here, stripe-patterned rough (SR-TENG) fabricated by laser ablation and molding proposed. exhibits excellent deformation properties, allowing more effective contact area between tribolayers. Additionally, localized surface-edge enhanced electric field at stripe boundaries improves transfer, thereby enhancing overall performance. SR-TENG achieved an open-circuit 97 V, short-circuit current 59.6 μA, instantaneous power 3.55 mW, density 1.54 W/m2. As harvester, successfully powered 150 LEDs. linear relationship was established coefficient determination R2 = 0.94, demonstrating high sensitivity 14.14 V/kPa. For practical application, novel two-digit switch developed based SR-TENG. This system enables control two different LEDs using single device, triggered applying light or hard press.
