“…The series configuration has also been chosen by other scientists. For example, recently, Beyranv and Gholizadeh (2020) developed a new flexible triboelectric (TE) nanogenerator (NGs) as a piezoelectric material. They observed that NGs connected in the series configuration to each other have a higher output than that of NGs connected in the parallel configuration.…”

We have designed a piezoelectric power nano-generator unitcell (device) where gas molecules are moving in Brownian motion and these molecules collide with a piezoelectric material. Due to the collision by gas molecules on the piezoelectric material, a voltage difference is induced across the piezoelectric material. We developed a simple model to calculate the voltage and power generation by using the method of statistical mechanics. Here we considered that gas molecules are not interacting with each other. We have created a design to connect nano-generator unitcells to form a chip in series configurations to enhance the production of the power nano-generation. Our design for the new power generator shows that as the thickness of the piezoelectric material increases so does the voltage generation. Our design can continuously generate electricity and this feature is better than solar panels that only work during daytime and windmills that cannot work without wind. It can work in a natural atmosphere environment. In the future when a new way of printing chips at low costs is discovered, then generating electricity will be very cheap using our design.

“…A similar approach was investigated by Beyranvand and Gholizadeh (2020) 2019) introduced an all-printed 3D micro/nano hierarchically patterned structure for a CNF aerogel-PDMS TENG. The silver electrodes, CNF aerogel and PDMS layers were printed directly on PET substrates and assembled in a vertical contact-separation structure.…”

Triboelectric nanogenerators (TENGs) are versatile electronic devices used for environmental energy harvesting and self-powered electronics with a wide range of potential applications. The rapid development of TENGs has caused great concern regarding the environmental impacts of conventional electronic devices. Under this context, researching alternatives to synthetic and toxic materials in electronics are of major significance. In this review, we focused on TENGs based on natural polysaccharide materials. Firstly, a general overview of the working mechanisms and materials for high-performance TENGs were summarized and discussed. Then, the recent progress of polysaccharide-based TENGs along with their potential applications reported in the literature from 2015 to 2020 was reviewed. Here, we aimed to present polysaccharide polymers as a promising and viable alternative to the development of green TENGs and tackle the challenges of recycling e-wastes.

“…As discussed earlier (Sections 1.2.1 and 2.3), the cellulose derivatives offer a wide range of processing opportunities for manipulating not only the morphologies and surface properties of cellulose, but also effortless blending with other polymers and piezoelectric materials. This has enabled the research focus on developing triboactive aerogels, [122,123] castable polymer film, [101,109,124] binders for efficient triboactive material coating, [95,124,125] and multiscale hierarchical nanostructures for tailoring roughness and hydrophobicity for TENGs (Table 2). [126][127][128] Overall, fabrication of TENG utilizing cellulose materials offers unique opportunities for less-refined wood biomass in big data analytics, recycling paper and pulp waste into energyharvesting building materials, tuning the performance of TENG by tailoring the morphologies (nanostructure, aerogels and coating) and surface functionalization of cellulose.…”

Developing nanogenerators (NGs) is achieved by exploiting the piezoelectric, triboelectric, and pyroelectric effects of both organic and inorganic materials. Many exhibit beneficial electrical properties (dielectric, conductive, or insulating) or have surfaces that are polarizable upon friction or physical contact. Recently, biomass‐derived materials and recycled materials, whose electrical activity can be induced, are explored for application in the design of more sustainable, cost‐effective, biodegradable, disposable NGs, and have demonstrated a wide range of output (microenergy) power densities. Among them, cellulose, the most abundant biopolymer, is found to offer excellent opportunities for designing and manufacturing NGs with multifunctional capacities. Cellulose can be derived into varied forms with multifunctionalities and physical morphologies. This account provides an overview of how cellulose is utilized in creating NGs based on piezoelectric, triboelectric, and pyroelectric effects. Because the mechanical properties of cellulose are tunable, current research trends on NGs originate with the triboelectric effect. The discussion here focuses on design, fabrication methods, achievable electrical power output, and combinations with other materials and devices. Challenges in efficient fabrication and consistent power densities, and opportunities for integrating different technologies and developing more sustainable (in terms of economic, environmental, and ecological) nature–human–machine interfacial devices are also discussed.
