Metal−organic frameworks (MOFs) have been used in triboelectric nanogenerators (TENGs) to improve the output performance because of their designability and great triboelectricity. However, there still lacks detailed and systematic research about the influence of the morphology of MOFs to the outputs of TENGs. Here, ZIF-67 particles with three different sizes were successfully prepared and filled with silk fibroin (SF) to prepare composite films. TENGs composed of ZIF-67/SF composites were assembled and tested. Results indicated that the output of the TENGs was very sensitive to filler particle size and mass ratios. Owing to the much higher charge-trapping property, ZIF-67 with the smallest particle size (500 nm) increased the output power density by 5 times with the value of 144 μW cm −2 . With the enhanced output power density, TENGs based on ZIF-67/SF composite films were applied more widely for harvesting mechanical energy in real life.

“…The ZIF-67 maintains its original morphology after being attached with electrodes. [219] Shaukat et al prepared MOF-5, which is having high chemical, thermal stability having rod-like morphology and tunable porosity shows outstanding properties in the fabricated TENG. Whereas, the MOF-5 acts as tribo-positive layer and polytetrafluoroethylene (PTFE) acts as a tribo-negative layer in TENG and achieved a maximum output Voc is 484 V while Isc achieved 40 μA with an efficient power of 3,174 μW.…”

Being cognizant of modern electronic devices, the scientists are continuing to investigate renewable green‐energy resources for a decade. Amid different energy harvesting systems, the triboelectric nanogenerators (TENGs) have been found to be the most promising mechanical harvesting technology and have drawn attention to generate electrical energy. Thanks to its instant output power, choice to opt for wide‐ranging materials, low maintenance cost, easy fabrication process and environmentally friendly nature. Due to numerous working modes of TENGs, it is dedicated to desired application at ambient conditions. In this review, an advance correlation of TENGs have been explained based on the variety of nanostructures, including 0D, 1D, 2D, 3D, metal organic frameworks (MOFs), coordination polymers (CPs), covalent organic frameworks (COFs), and perovskite materials. Moreover, an overview of previous and current perspectives of various nanomaterials, synthesis, fabrication and their applications in potential fields have been discussed in detail.

Oral healthcare monitoring is a vital aspect of identifying and addressing oral dental problems including tooth decay, gum pain, and oral cancer. Day by day, healthcare facilities and regular checkups are becoming more costly and time-consuming. In this context, consumers are moving toward advanced technology, such as bite sensors, to obtain regular data about their occlusal chewing patterns and strength. The triboelectric nanogenerator (TENG) can potentially eliminate the need for a battery by simply converting abundant vibrations from nature or human motion into electrical energy. In this work, biomaterials are obtained from biowastes such as cellulose from wood waste, chitosan from crab shells, and gelatin from fish scales. All wastes are biodegradable, and our work aims at sustainability and waste hierarchy. The single electrode mode-based TENG was designed and fabricated using biodegradable poly(vinyl alcohol) (PVA)−biomaterial composites, rice paper as a substrate, and edible silver leaf as an electrode. The highest electrical output was obtained for PVA/ chitosan 10 wt % composite-based TENG (PC10) of about 20 V, 200 nA, and 12 nC. The biomechanical energy harvesting was measured, and powering of LED was demonstrated using a PC10 TENG device. A biocompatible bite sensor based on the TENG was used to measure the biting force of a dummy teeth model to demonstrate its potential use in dental health applications. It indicates the promising future value of disposable oral medication devices without any invasive surgery or injection.
