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.

The development of self-powered water purification technologies for decentralized applications is crucial for ensuring the provision of drinking water in resource-limited regions. The elimination of the dependence on external energy inputs and the attainment of self-powered status significantly expands the applicability of the treatment system in real-world scenarios. Hybrid energy harvesters, which convert multiple ambient energies simultaneously, show the potential to drive self-powered water purification facilities under fluctuating actual conditions. Here, we propose recent advancements in hybrid energy systems that simultaneously harvest various ambient energies (e.g., photo irradiation, flow kinetic, thermal, and vibration) to drive water purification processes. The mechanisms of various energy harvesters and point-of-use water purification treatments are first outlined. Then we summarize the hybrid energy harvesters that can drive water purification treatment. These hybrid energy harvesters are based on the mechanisms of mechanical and photovoltaic, mechanical and thermal, and thermal and photovoltaic effects. This review provides a comprehensive understanding of the potential for advancing beyond the current state-of-the-art of hybrid energy harvester-driven water treatment processes. Future endeavors should focus on improving catalyst efficiency and developing sustainable hybrid energy harvesters to drive self-powered treatments under unstable conditions (e.g., fluctuating temperatures and humidity).

Flexible and wearable sensors are of paramount importance in applications like electronic skin, health monitoring, and human–computer interactions. However, mass production of flexible sensors with versatile, high-performance, low-cost, and easy-to-dispose features remains a huge challenge. Herein, based on a strategy of bionics inspired by the slit receptors in arthropods, a flexible paper-based sensor with macrocracks is developed. And a large number of irregular microdomes are formed on the surfaces of folded paper, which attributes to the conductive composites constructed by carbon nanomaterials and poly(dimethylsiloxane) (PDMS). Macrocracks and microdomes are helpful to achieve outstanding dual mechanical strain/pressure signal sensing functions. The materials used and the fabricating method employed are cost-efficient and convenient. As a result, the paper-based sensor exhibits a gauge factor of 64 within the strain range of 1% and excellent stability over 1500 cycles. When serving as a pressure sensor, it shows a high sensitivity of 1.4 kPa–1 in the range within 0.5 kPa. Also, the paper-based sensor shows an environmentally friendly feature and can be almost disposed of naturally, indicating that the bioinspired sensor could serve as disposable green flexible electronics, which has potential usage in wearable applications.
