“…Different mechanical excitations used to study different TENGs perform more complex analyses. For example, the petal rose [60] and Rhododendron leaf [61] are able to provide 24 µW and 15 µW cm −2 for mechanical excitations of 2 Hz, 100 N, and 10 Hz, 0.9 N, respectively https://doi.org/10.1007/s40820-020-0373-y © The authors (Table 1). These observations emphasize highly nonlinear behavior of TENGs and demand establishing a standard for their testing.…”

“…With the continuous development of the bionics, superhydrophobic, and super‐adhesive properties of biological surfaces of climbing organism, such as virginia creeper, geckos, and aquarlus elongatus, have attracted extensive attention from the scientific and medical communities [11–13] . The special surface wettability and super‐adhesive are mainly determined by the surface geometric structure and chemical composition [14,15] …”

With the continuous development of bionics, such as, geckos and virginia creeper with both superhydrophobic and super‐adhesive, the surface wetting and super‐adhesive properties of various porous materials have attracted extensive attention of the scientific and medical communities. Here, the honeycomb polyurethane (PU) porous films with strong adhesion were successfully prepared by microphase separation method and the effects of growth parameters on their microstructure and adhesive strength to ice were investigated. It was found that a high relative humidity (e.g., 100%) and a low solution concentration (e.g., 2%) facilitated the formation of ordered honeycomb PU porous films, and as‐prepared PU pores with average pore diameter as small as 5 μm are better ordered and more uniform than these in related documents. Although the contact angle of water droplets on the surface of PU porous films increased from the premodification value of 85–130° to more than 160° after surface modification with polydopamine (PDA), the corresponding rolling angle remained approximately constant (180°), indicating that the surface of PU porous films has strong adhesion similar to geckos and virginia creeper. Furthermore, at lower temperature, the PU porous films exhibited the high adhesive strength of 142.13 kPa on ice, which was strongly dependent on the porous microstructures and surface compositions. The improved adhesive behavior to ice of honeycomb PU porous films modified with PDA provides new strategies for surface modification of materials and potential applications in medical domain.

The triboelectric nanogenerator (TENG) is a new type of energy generator first demonstrated in 2012. TENGs have shown potential as power sources for electronic devices and as sensors for detecting mechanical and chemical stimuli. To date, studies on TENGs have focused primarily on optimizing the systems and circuit designs or exploring possible applications. Even though triboelectricity is highly related to the material properties, studies on materials and material designs have been relatively less investigated. This review article introduces recent progress in TENGs, by focusing on materials and material designs to improve the electrical output and sensing performance. This article discusses the current technological issues and the future challenges in materials for TENG.
