“…However, the surface layer gradually wears out with increasing usage, which is not conducive to the long‐term usage of the TENG. [ 92 ] To achieve a substantial and stable improvement in the cellulosic triboelectric properties, surface‐charge‐density enhancement via dielectric modulation should be focused on.…”

The rapid rise of triboelectric nanogenerators (TENGs), which are emerging energy conversion devices in advanced electronics and wearable sensing systems, has elevated the interest in high-performance and multifunctional triboelectric materials. Among them, cellulosic materials, affording high efficiency, biodegradability, and customizability, are becoming a new front-runner. The inherently low dielectric constant limits the increase in the surface charge density. However, owing to its unique structure and excellent processability, cellulose shows great potential for dielectric modulation, providing a strong impetus for its advanced applications in the era of Internet of Things and artificial intelligence. This review aims to provide comprehensive insights into the fabrication of dielectric-enhanced cellulosic triboelectric materials via dielectric modulation. The exceptional advantages and research progress in cellulosic materials are highlighted. The effects of the dielectric constant, polarization, and percolation threshold on the charge density are systematically investigated, providing a theoretical basis for cellulose dielectric modulation. Typical dielectric characterization methods are introduced, and their technical characteristics are analyzed. Furthermore, the performance enhancements of cellulosic triboelectric materials endowed by dielectric modulation, including more efficient energy harvesting, high-performance wearable electronics, and impedance matching via material strategies, are introduced. Finally, the challenges and future opportunities for cellulose dielectric modulation are summarized.

Internet ofThings and wearable technology's quick development have opened up a vast market for sensor systems. However, typical sensors' external power supplies' short lifespan and expensive maintenance restrict them from being used more widely. Triboelectric nanogenerators (TENGs), a recently created mechanical energy harvesting and self-powered sensing device, show enormous promise to get over these restrictions. TENG can be used not only to power sensors instead of conventional chemical batteries but also be utilized to actualize sensing by taking advantage of the unique characteristics of the friction layer itself. Triboelectric nanogenerators efficiently provide crucial infrastructure for a new generation of sensing devices that gather data using several self-powered sensors in abundance. The recent progress in the development of TENGs applied in the sensor field is reviewed. First, the working mechanisms of solid-solid TENG and solid-liquid TENG are introduced. Subsequently, the development of TENG-based sensing systems and their application progress in self-powered temperature sensors, self-powered pressure sensors, self-powered humidity sensors, self-powered atmosphere sensors, self-powered wireless sensors, interface wetting status monitoring, solution property monitoring, and friction condition monitoring are highlighted. Finally, current challenges and open opportunities are discussed.

“…Synthetic polymers like PTFE, polyvinylidene fluoride (PVDF), Kapton, PDMS, and polyethylene terephthalate (PET) as typical TENG materials 38,65,[93][94][95] can release dangerous chemicals to the environment due to their incomplete degradation. 96 Thus, recently, there has been a great deal of development of bio-based TENGs by employing eco-friendly, simple, low-cost, degradable, and renewable biomaterials such as wood, [97][98][99][100][101] silk, [102][103][104][105][106][107][108][109][110] cellulose, 101,[111][112][113][114][115][116][117][118][119][120][121] starch, 96,120,122,123 and chitosan [124][125][126] instead of non-renewable synthetic polymers.…”
