“…To deal with the complex structure and low output power density of current droplet-based TENGs (DEGs), Li et al demonstrated a rain droplet-based electricity generator with a simple open structure (SCE-DEG), mainly an upper electrode, a layer of PTFE film, a lower electrode, and a load, as depicted in Figure 4c [114]. The SCE-DEGs can be arranged and connected in parallel to harvest large-scale raindrop energy in sloping buildings.…”

Facing the energy consumption of a huge number of distributed wireless Internet of Things (IoT) sensor nodes, scavenging energy from the ambient environment to power these devices is considered to be a promising method. Moreover, abundant energy sources of various types are widely distributed in the surrounding environment, which can be converted into electrical energy by micro-nano energy harvesters based on different mechanisms. In this review paper, we briefly introduce the development of different energy harvesters according to the classification of target energy sources, including microscale and nanoscale energy harvesters for vibrational energy sources, microscale energy harvesters for non-vibrational energy sources, and micro-nano energy harvesters for hybrid energy sources. Furthermore, the current advances and future prospects of the applications of micro-nano energy harvesters in event-based IoT systems and self-sustained systems are discussed.

Polymers obtained from biomass are promising alternatives to petrobased polymers owing to their low cost, biocompatibility, and biodegradability.Lignin, a complex aromatic polymer containing several functional hydrophilic and active groups including hydroxyls, carbonyls, and methoxyls, is the second most abundant biopolymer in plants. In particular, sustainable ligninbased gels are emerging as an appealing material platform for developing energy-and sensing-related applications owing to their attractive and tailorable physiochemical properties. This study describes the preparation strategies of lignin-based gels according to previously reported methods, with significant attention on the diverse performance of lignin-derived gel materials. Additionally, a detailed review of lignin-based gels utilized as an important resource in diverse fields is provided. Finally, a future vision on challenges and their possible solutions is presented.

Self-powered sensors have emerged as a promising solution to this challenge, offering a range of benefits such as low cost, high stability, and environmental friendliness. One of the most promising self-powered sensor technologies is L-S TENG, which stands for the liquid-solid triboelectric nanogenerator. In this review paper, the working principle with three basic modes has been briefly introduced firstly. After that, affecting parameters to L-S TENG are reviewed based on the properties of the liquid and solid phases. With different working principles, L-S TENG has designed a lot of structure that works as self-powered sensor for pressure/force change, liquid flow motion, concentration, and chemical detection or biochemical sensing. On the other hand, the continuous output signal of TENG plays an important role in a real-time sensor which is extremely necessary for the development of the Internet of Things.
