“…[31,32] Chitosan which is obtained from chitin (shells of crabs or shrimp) was observed as a highly electropositive material because of the presence of amino groups in it and used in the fabrication of TENG. [33] Zhong and his peers also explored chitin along with cellulose (from wood and cotton), egg white, silk fiber (from cocoon), and rice paper (from wheat, rice, and corn) for the generation of energy from fully biocompatible TENG. [34] Another research showed the relationship of cellulose content and surface morphology with performance of TENG.…”

In today's world, people are surrounded by smart wireless devices which require sustainable and eco‐friendly power source. Triboelectric nanogenerator (TENG) is emerging as an imperative source to produce clean, cost‐effective, and easily fabricated battery‐less devices. The emphasis is on using biomaterials to play a vital role for the fabrication of such self‐ powered system. Herein, an approach is discussed to fabricate a novel TENG from the waste biomaterials (garlic tunic, onion tunic, and almond peel) which successfully harvests the electrical energy from daily human motions (walking and running). Egg shell membrane–polytetrafluoroethylene (ESM–PTFE) TENG generates 56.6 V/0.53 μA and is closely followed by garlic tunic–PTFE TENG with 44.6 V/0.36 μA, onion tunic–PTFE TENG with 41.4 V/0.32 μA, and almond peel–PTFE TENG with 40.2 V/0.29 μA, respectively. Moreover, ESM‐based TENG performance is examined using all other biomaterial combinations. These TENGs produce sufficient energy that can power an array of tens of green light‐emitting diodes (LEDs). Finally, the power from human activities is harvested to control small portable electronic devices.

“…The phenomenon of surface electrification upon contact has been documented for over 2600 years, and many applications have been developed based on this phenomenon. − Since 2012, the triboelectric nanogenerator (TENG) proposed by Wang, which uses the coupling of contact electrification and electrostatic induction to generate electrical energy, has been a further understanding of the mechanism of frictional power and gradually developing as one technology in the field of energy harvesting. − The operation of a TENG mainly relies on the interfacial electrostatic field, which outputs power due to the displacement current induced by mechanical motion. − So far, TENGs can harvest energy from tribo-contacts at the solid-solid interface, − solid-liquid interface, − liquid-liquid interface, , and even solid-gas interface, while the applications of TENGs have also been successfully developed in many areas, including micro/nano power source, − self-powered sensors, − blue energy harvester, − and high-voltage sources. − However, little progress has been proposed related to energy generation at the liquid-gas (L-G) interface. It is commonly known that lightning on rainy days and lightning of dressing coats are the results of triboelectricity, which can be an undeveloped energy source.…”

Study of Contact Electrification at Liquid-Gas Interface

It is known that the suspended liquid droplets in clouds can generate electrostatic charges, which finally results in the lightning. However, the detailed mechanism related to the contact-electrification process on the liquid-gas (L-G) interfaces is still poorly understood. Here, by introducing an acoustic levitation method for levitating a liquid droplet, we have studied the electrification mechanism at the L-G interface. The tribo-motion between water droplets and air induced by the ultrasound wave leads to the generation of positive charges on the surface of the droplets, and the charge amount of water droplets (20 μL) gradually reaches saturation within 30 s. The mixed solid particles in droplets can increase the amount of transferred charge, whereas the increase of ion concentration in the droplet can suppress the charge generation. This charge transfer phenomenon at L-G interfaces and the related analysis can be a guidance for the study in many fields, including anti-static, harvesting rainy energy, micro/nano fluidics, triboelectric power generator, surface engineering, and so on. Moreover, the surface charge generation due to L-G electrification is an inevitable effect during ultrasonic levitation, and thus, this study can also work for the applications of the ultrasonic technique.

“…[30][31][32][33][34] The concept of TENG was first introduced by Wang et al [35] TENGs produce electrical output based on triboelectrification and electrostatic induction in response to external mechanical stimulations. [36][37][38][39][40][41][42] They can be utilized as active sensors via directly correlating the generated electrical signal with the mechanical triggering. TENG-based sensors can use the generated electric signal to self-power themselves as well.…”

There is a critical shortage in research needed to explore a new class of multifunctional structural components that respond to their environment, empower themselves and self-monitor their condition. Here, the novel concept of triboelectric nanogenerator-enabled structural elements (TENG-SEs) is proposed to build the foundation for the next generation civil infrastructure systems with intrinsic sensing and energy harvesting functionalities. In order to validate the proposed concept, proof-of-concept multifunctional composite rebars with built-in TENG mechanisms are developed. The developed prototypes function as structural reinforcements, nanogenerators, and distributed sensing mediums under external mechanical vibrations. Experiential and theoretical studies are performed to verify the electrical and mechanical performance of the developed self-powering and self-sensing composite structural components. The capability of the embedded structural elements to detect damage patterns in concrete beams at multiscale is demonstrated. Finally, it is discussed how this new class of TENG-SEs can revolutionize the large-scale distributed monitoring practices in civil infrastructure and construction fields.
