“…Advances in the Internet of Things and wearables have been highly favored by the initiative of producing flexible electronics and self-powered devices that harvest energy from mechanical movement/environment to convert it into electrical energy [1,2]. When considering the use of these devices as implantable or components [3,4] that operate in contact with the skin, the requisites of non-toxicity and biocompatibility are critical [5], making relevant the development of bio-based triboelectric nanogenerators (TENGs) [6][7][8] with several applications in water-harvesting systems [9], sweat sensors [10], and sensors for tactile perception [11].…”

Developing metal-free electrodes for prototypes of bio-based devices is an essential step in producing non-toxic components for implantable devices and wearables. In particular, the advancement in self-powered devices is a hot topic for several applications due to the possibility of creating free-battery devices and sensors. In this paper, the modification of bacterial cellulose by the progressive incorporation of carbon black (a conductive filler) was explored as a prototype for bio-based electrodes for triboelectric nanogenerators. This process was controlled by the percolation pathways’ activation through the contact of carbon black grains with the bacterial cellulose membrane, which represents a critical step in the overall process of optimization in the power output performance, reaching an open circuit voltage value of 102.3 V, short circuit current of 2 μA, and power density of 4.89 μW/cm2.

“…In recent years, triboelectric nanogenerators (TENGs) have been considered a transformation technology in harvesting mechanical movement for conversion into electric energy. This process is established by the coupling effect of contact electrification and electrostatic induction derived from Maxwell's displacement current theory [1][2][3][4]. The most promising materials for use in triboelectric nanogenerators must combine an excellent capability to gain or lose electrons, high surface area, roughness, and an adequate surface distribution of charges that make possible the generation, transfer, storage, and minimal dissipation of charges along with the TENG operation [5].…”

The development of more efficient friction layers for triboelectric nanogenerators is a complex task, requiring a careful balance of various material properties such as morphology, surface roughness, dielectric constant, and surface potential. In this study, we thoroughly investigated the use of cellulose acetate modified with different concentrations of zinc oxide and titanium dioxide to enhance energy harvesting for the TENG. The results indicate that the roughness degree is influenced by the homogeneous degree/aggregation level of doping agents in cellulose acetate membranes, leading to the best performance of open circuit voltage of 282.8 V, short-circuit current of 3.42 µA, and power density of 60 µW/cm2 for ZnO-doped cellulose acetate membranes.

“…In recent years, swift development in triboelectric nanogenerator-based sensors has been witnessed. Owing to good cost-efficiency, structural easiness, and compact size, they are widely studied in monitoring physical parameters including temperature, − velocity, , displacement, , and pressure. , These studies also involve monitoring the physical status of the liquid-phase substances. Relevant studies are primarily performed with liquid–solid contact separation mode triboelectric nanogenerators. − They can be categorized based on various application purposes, such as monitoring liquid droplets, , monitoring flows, monitoring waves, and monitoring liquid levels. − For instance, Zeng et al proposed a raindrop sensor using a liquid–solid triboelectric nanogenerator to detect rainfall information.…”

Liquid-level sensors are widely employed for monitoring and alarming liquid levels in storage tanks and vessel compartments. They are essential in promptly comprehending the container's liquid-level status. In this study, an adaptive dual-mode triboelectric nanogenerator is proposed for real-time liquid-level monitoring. It is the combination of liquid−solid contact separation electrification and solid−solid contact electrification that forms the working mode of the studied liquid-level sensor. In contrast to the single operating mode of the liquid−solid contact separation triboelectric nanogenerator, the studied device provides additional output from solid−solid contact electrification. Unlike the single liquid−solid triboelectric nanogenerator, the output of the adaptive dual-mode triboelectric nanogenerator will not decline with ion concentrations in the liquid medium. Monitoring the open-circuit voltage signal reveals a correspondence between the signal and the liquid-level oscillation. Therefore, open-circuit voltage can be used to indicate liquid-level variations in real time.
