Summary: This study utilizes fragile and rigid mica to improve the performance of triboelectric nanogenerators (TENGs). By exfoliating mica into 2D nanosheets and electrospinning them into flexible thermoplastic polyurethane (TPU) nanofibers, the transferred charge of the TENG significantly increases. The mica also enhances the positive electrostatic surface potential (ESP) of TPU, leading to a higher power density in the TENG.

Summary: The tactile perception of fine textures in humans is mediated by fingertip skin, which is crucial for obtaining environmental information and manipulating objects precisely. Electronic skins based on triboelectric nanogenerator (TENG) have shown impressive applications in fine texture recognition by accurately mapping surface textures to electrical signals and revealing physical information. The fingerprint-inspired electronic skin (FE-skin) developed in this study can effectively detect and identify different textures by mimicking human fingerprints' morphology, achieving high accuracy rates in texture recognition through processing electrical signals with artificial neural networks. This technology demonstrates TENG's potential superiority in bionic tactile perception and has broad application prospects in humanoid robots, intelligent prostheses, and precise human-machine interaction.

Summary: A single-electrode triboelectric nanogenerator (S-TENG) based on polydimethylsiloxane (PDMS) surface modified with zinc oxide nanotubes (ZnO NTs) was developed using a simple and cost-effective chemical bath deposition method. The ZnO NTs increased the surface roughness and provided a suitable path for electron transfer. Compared to the pristine PDMS-based S-TENG, the modified PDMS showed significant enhancements in output voltage, current, and power density. The effect of frequency was also investigated, and the maximum output voltage was achieved with a specific dimension. The working process of the S-TENG was examined using COMSOL software. This work provides insight into the potential electro-optic applications, such as smartphone screens, utilizing the sliding-electrification characteristics of ZnO.

Summary: In this study, rice husk carbon (RHC) was examined as a filler material for EPDM composites as an efficient alternative to traditional carbon black. The results showed that the EPDM composite with ultrasonically treated and silane treated RHC exhibited similar tensile strength to carbon black, along with higher elongation at break and lower compression set value. The ultrasonic treatment of RHC led to improved particle distribution, smaller particle size, and increased surface area, contributing to the development of high-performance EPDM composites.
