The signals generated by these stimuli are transferred to the central neural network and brain to provide an appropriate response. In addition, biological skin possesses unique characteristics, such as stretchability, self-healing ability, and mechanical toughness. [1][2][3] It also provides an effective barrier against ambient elements such as chemicals, gases, radiation, and external biological agents.Electronic skin (e-skin) is an artificial smart skin composed of various electronic sensors distributed on a single uniform surface or stacked on multiple surfaces. It mimics some of the biological skin senses and provides a promising sensing platform for key application areas such as wearable sensors, robotics, and prosthetics (Figure 1). [1,[4][5][6][7][8][9][10][11] However, serious concerns have arisen regarding the production of electronic waste (e-waste), the influence of e-skin on human health, the safety of wearable electronic devices, costs, and environmental limitations. These concerns have encouraged researchers to develop biocompatible, renewable, sustainable, and biodegradable flexible wearable detection devices and biosensing platforms. [12][13][14][15][16] Biological skin regularly regenerates the old superficial layer of the epidermis with new skin cells during the healing process. Inspired by this natural degradation cycle, artificial biodegradable skin-based electronics should be designed for programmable degradation, in contrast to conventional electronic materials. To achieve this goal, the development of biocompatible, environmentally friendly electronic systems that can be used for the fabrication of biodegradable and sustainable e-skins is important.Various low-cost, nontoxic, renewable, and natural substances and polymer-based materials that can be applied to the development of sustainable, biodegradable e-skins and alleviate the environmental and health risks of e-waste materials are available. [17][18][19][20][21][22] E-waste disrupts the biological activity of microbial enzymes and their metabolisms, which decreases the resistance and the diversity of soil-based microbial communities. [23] In addition, in the human body, the accumulation of metals and metalloids used in the fabrication of conventional electronics can cause a range of biophysical malfunctions and diseases, such as liver damage by Cu, behavioral disorders by Pb, and lung cancer and kidney damage by Cd. [24][25][26][27] The rapid growth of the electronics industry and proliferation of electronic materials and telecommunications technologies has led to the release of a massive amount of untreated electronic waste (e-waste) into the environment. Consequently, catastrophic environmental damage at the microbiome level and serious human health diseases threaten the natural fate of the planet. Currently, the demand for wearable electronics for applications in personalized medicine, electronic skins (e-skins), and health monitoring is substantial and growing. Therefore, "green" characteristics such as biodegradability, self-healin...

“…Among such energy sources, mechanical energy such as vibrating, flow of water, drop of rain, wind and human body movement indicated a promising resource as the resource is widely available but generally being neglected [1]. Many attempts have been made to energy harvesting technology in powering miniaturized electronics, including selfpowered systems, and wearable devices which need to generate a small-scale power output as alternative of using battery [2][3][4][5].…”

Most global problems are being solved by using sustainable energy harvesting technologies to retain the social ecosystem in great condition. The triboelectric nanogenerator (TENG) which is a renewable energy harvesting device, collects the waste mechanical energy from its surroundings and performs the electric signal conversion. TENG have garnered increased attention in recent years by offering prospective use in energy harvesting technology. Particularly, there is a need for flexible energy conversion that serves as a power supply for portable electronic equipment. In this study, ZnO nanosheet thin film prepared on the flexible conductive aluminium foil through a low temperature immersion technique was used to generate electrical energy. The effect of heat treatment on ZnO nanosheet thin film was also investigated on the surface morphology, strutural properties and nanogerator performance. The high density of interconnected ZnO nanosheet were observed before and after heat treatment as confirmed by FESEM studies. The analysis using XRD confirmed that ZnO nanosheet thin film was successfully deposited on the aluminium foil. Additionally, the ZnO nanosheet thin films improved significantly with heat treatment, enhancing their crystalline quality. The triboelectric nanogenerator (TENG) was successfully constructed in contact and separation mode using Kapton tape on top and ZnO nanosheet thin film on the bottom to generate electricity by a force of hand pressing. The output electrical voltage of the device doubled from around 2 V to 4 V after underwent the heat treatment. This study provides an essential insight into fabrication of TENG using the ZnO nanosheet thin film through a clean and effective method for nanogenerator applications.

“…Among them, the PDMS polymer stands out from the numerous negative triboelectric layer materials due to its flexibility, good electronegativity, and easy processing to mass production. It is widely used in TENGs, selfpowered sensors, and biosensing applications for energy harvesting [10][11][12]. It has been previously demonstrated that PDMS-based PGs and TENGs are used not only as wireless energy harvesters, but also as highly sensitive and flexible biocompatible pressure/strain sensors to detect vibration or human motion [13][14][15].…”

As versatile energy harvesters, triboelectric nanogenerators (TENGs) have attracted considerable attention in developing portable and self-powered energy suppliers. The question of how to improve the output power of TENGs using cost-effective means is still under vigorous investigation. In this paper, high-output TENGs were successfully produced by using a simple and low-cost lotus-leaf-bionic (LLB) method. Well-distributed microstructures were fabricated via the LLB method on the surface of a polydimethylsiloxane (PDMS) negative triboelectric layer. 2D MXene (Ti3C2Tx) and graphene were doped into the structured PDMS to evaluate their effects on the performance of TENG. Owing to merits of the MXene doping and microstructures on the PDMS surface, the output power of MXene-doped LLB TENGs reached as high as 104.87 W/m2, which was about 10 times higher than that of graphene-doped devices. The MXene-doped LLB TENGs can be used as humidity sensors, with a sensitivity of 4.4 V per RH%. In addition, the MXene-doped LLB TENGs were also sensitive to human body motions; hence, a foot health monitoring system constructed by the MXene-doped LLB TENGs was successfully demonstrated. The results in this work introduce a way to produce cost-effective TENGs using bionic means and suggest the promising applications of TENGs in the smart monitoring system of human health.
