“…During the experimentation it has been noted that the variation of current in the EL depends on size of the droplets as well. It was found that 25 mA of current is typically sufficient to disinfect virus particles [ [33] , [34] , [35] , [36] ]. For efficiency of the mask, tiny droplets were spread on EL from different sized orifice on the cap of containers were used to create droplets were spread on EL.…”

Usage of a face mask has become mandatory in many countries after the outbreak of SARS-CoV-2, and its usefulness in combating the pandemic is a proven fact. There have been many advancements in the design of a face mask and the present treatise describes a face mask in which a simple triboelectric nanogenerator (TENG) with an electrocution layer may serve the purpose of filtration and deactivation of SARS-CoV-2. The proposed mask is designed with multilayer filters, in which the inner three layers act as a triboelectric (TE) filter and the outer one as an electrocution layer (EL). The viral particles experience a mildshock in EL due to the electric field produced between the electrocution layers by contact electrification. Four pairs of triboelectric series fabrics, i.e. polyvinylchloride (PVC)-nylon, polypropylene (PP)-polyurethane (PU), latex rubber-PU, polyimide (PI)-nylon are studied to establish the efficacy of the mask. The motional force exerted on triboelectric filter materials can produce sufficient electric power to activate EL. The proposed mask can be used by a wide range of people because of its triboelectric self-powering (harvesting mechanical energy from daily activities, e.g. breathing, talking or other facial movements) functionalities to ensure effective filtration efficiency. More importantly, it is expected to be potentially beneficial to slow down the devastating impact of COVID-19.

The increasing needs to power trillions of sensors and devices for the Internet of Things require effective technology to harvest small-scale energy from renewable natural resources. As a new energy technology, triboelectric nanogenerators (TENGs) can harvest ambient mechanical energy and convert it into electricity for powering small electronic devices continuously. In this chapter, the fundamental working mechanism and fundamental modes of a TENG will be presented. It can harvest all kinds of mechanical energy, especially at low frequencies, such as human motion, walking, vibration, mechanical triggering, rotating tire, wind, moving automobile, flowing water, rain drops, ocean waves, and so on. Such variety of energy harvesting methods promises TENG as a new approach for small-scale energy harvesting.

“…Because paper is rich of surface hydroxyl groups, which may form hydrogen bonds with the functional groups of various conductive materials, the conductive layer can be firmly anchored onto the surface of the paper . Therefore, paper‐based TENGs (P‐TENGs) have been investigated intensively most recently, despite that the following critical challenges still remain to be solved. First, paper sheets usually suffer from poor wet mechanical strength.…”

Among various energy harvesting technologies, triboelectric nanogenerators (TENGs) as newly invented mechanical energy harvesters have attracted significant attention due to their simple and diverse device structures as well as abundant materials choices. [10][11][12] Recently, breathable/wearable TENGs based on textiles have also been fabricated. [13,14] However, due to poor adhesion between textile fibers and electrode materials, textile-based TENGs are prone to lose their surface conductive layer after repeated mechanical deformation. A promising alternative to textiles is porous paper. Because paper is rich of surface hydroxyl groups, which may form hydrogen bonds with the functional groups of various conductive materials, the conductive layer can be firmly anchored onto the surface of the paper. [15,16] Therefore, paper-based TENGs (P-TENGs) have been investigated intensively most recently, [17][18][19][20][21][22] despite that the following critical challenges still remain to be solved. First, paper sheets usually suffer from poor wet mechanical strength. Therefore, the mechanical and electrical properties of most reported paper-based electrodes are severely affected by the environment. Second, a typical P-TENG consists of a paper-based electrode layer and a plastic or rubber triboelectric layer. [18][19][20][21][22] The presence of dense plastic/rubber film severely limits the air permeability of the device. Even though electrospun nanofiber membranes have been utilized as the triboelectric layer to improve breathability, [23][24][25] the complex and expensive fabrication process of such membranes restricts their viable applications. Furthermore, the paper electrode layer and the triboelectric layer as two independent films need to be adhered by double sticky tape, which considerably reduces the flexibility and breathability of the resulting P-TENG.On the other hand, the voltage and current outputs of a TENG are intermittent and pulsed. For stable and continuous power supply, supercapacitors (SCs) have been widely used as the energy storage devices for TENGs to form power units. [2,[26][27][28] However, most reported self-power units integrated with wearable TENGs and SCs require mechanical motion at relatively high frequencies (5-10 Hz) or lengthy charging times to reach the working voltages of electronic devices. This may be attributed to both the small power output of TENGs and the fast selfdischarge process of SCs. [29] Therefore, the development of SCs A breathable and wearable self-charging power system is developed by integrating paper-based triboelectric nanogenerator (P-TENG) and supercapacitor (P-SC). The felt side and wire side of highly porous and mechanically robust air-laid paper are utilized as the triboelectric pair of the P-TENG, which not only shows remarkable flexibility and clothlike air permeability (333 mm s −1 ), but exhibits exceptional wet stability (85% voltage retention after four soaking cycles). To match the triboelectric output, the self-discharge behavior of the P-SC is compr...
