Fully sustainable and high-performance fish gelatin-based triboelectric nanogenerator for wearable movement sensing and human-machine interaction

Low-cost, environmentally friendly and high-performance cellulose-based triboelectric nanogenerator for self-powered human motion monitoring

“…We prepared 2mmol/L PDA solution (Sun et al, 2021b), and CNF modi cation was performed in this PDA solution. We fully dispersed 0.5 g of CNFs (dry weight) into the PDA solution, which was stirred at room temperature for 3 h. When the reaction is su cient, the suspension was poured into a G5 sand core funnel equipped with a microporous lter membrane.…”

“…PDA has attracted extensive research attention in composite design because of its remarkable adhesion, conductivity, and oxidation resistance. (Sun et al, 2021a). Due to its unique morphological advantages, CNFs have more energy collection points than many other materials.…”

An eco-friendly gelatin based triboelectric nanogenerator for a self-powered PANI nanorod/NiCo2O4 nanosphere ammonia gas sensor

“…It is obtained by processing collagen extracted from bones and skins of animals, which is extensively used as an excipient and thickener in the food industry. 24,25 Gelatin holds advantages of inexpensiveness, biocompatibility and degradability. It is also rich in amino acid residues with electron donor groups, which can serve as electron donors and give gelatin potent capability to lose electrons during the process of contact and separation.…”

Highly Enhanced Triboelectric Performance from Increased Dielectric Constant Induced by Ionic and Interfacial Polarization for Chitosan Based Multi‐Modal Sensing System

“…[ 14,15 ] However, most TENGs developed so far are based on synthetic polymers that are not biocompatible or biodegradable, [ 16–18 ] which limits their application in bio‐signal detection and poses irreversible damage to the environment such as crop production, land fertility decline, and groundwater pollution. [ 19,20 ]…”

“…[14,15] However, most TENGs developed so far are based on synthetic polymers that are not biocompatible or biodegradable, [16][17][18] which limits their application in bio-signal detection and poses irreversible damage to the environment such as crop production, land fertility decline, and groundwater pollution. [19,20] Among biodegradable materials, chitosan is a natural biopoly mer material extracted from chitin, the main component of marine crustacean shells with abundant nature sources. [21] It can be completely degraded in the environment.…”
