Summary: Stretchable triboelectric nanogenerators (s-TENGs) are promising power sources for self-powered wearable electronics. We propose an in-plane dual-electrode s-TENG based on differential surface functionalization to eliminate the external ground electrode. The s-TENG comprises fully stretchable materials and can achieve a high output power density of 3.5 W m(-2) by tapping the two electrode regions by hand.

Summary: With the rapid development of TENGs, self-powered, flexible, and wearable electronic devices have gained significant attention. This study prepared a composite fabric (HPC) with superhydrophobic and conductive properties, which was used as both a tribopositive material and electrode for TENGs. Compared to conventional TENGs with separate tribolayers and electrodes, the integrated HPC-TENG offers a simpler structure and lighter wear. Additionally, it demonstrates improved performance and high output even under high humidity conditions.

Summary: This study presents a self-healing triboelectric nanogenerator (TENG) fabricated using self-healing polyimide (PI) for energy harvesting and motion sensing. The PI-based TENGs exhibited excellent intrinsic self-healing properties, attributed to dynamic disulfide bond exchange and flexible PDMS fragments in the PI backbone. The output performance of the TENG was significantly improved due to CF3 electron-absorbing groups and siloxane fragments in the PI backbone. Practical applications of self-healing PI-based TENGs, including energy harvesting for commercial electronic devices and joint motion sensing, were demonstrated.
