Abstract. In recent years, triboelectric nanogenerators (TENGs) are used to harvest mechanical energy from ambient environment. These devices convert ambient energies (e.g. vibrations, breathing-driven, impacts or human body motions) into electricity based on the triboelectric effect. Furthermore, some TENGs can be successfully employed as selfpower active sensors because the electric response from the TENG is proportional to the magnitude of the mechanical motion. This study report on the design and development of a novel triboelectric nanogenerator, and its potential application as self-powered impact sensor. To prepare the TENG device, membranes of polyvinylidene fluoride (PVDF) and polyvinylpyrrolidone (PVP) nanofibers are sandwiched between copper electrode films and wrapped on PET films. The TENG works based on the triboelectric interaction between the membranes of nanofibers. After the preparation, the TENGs are subjected to several impacts by the drop-ball impact test. The purpose of the experiment is to analyse if the electric response of TENG is dependent on the energy of the impact. The results of the experiment are presented and discussed. The main contributions of this work are the preparation of a novel nanogenerator (TENG) based on the triboelectric interaction between polyvinylidene fluoride and polyvinylpyrrolidone sub-micron polymer fibers and the investigation of its potential use as a self-powered impact sensor.

“…The principle of the TENG is friction, and thus the surface roughness of the two layers must be an important parameter to be considered. In fact, So‐Yoon Shin et al., have recently shown that there is indeed a correlation between the TENG output and the surface roughness. With a decrease in the roughness from 17 nm to 1 nm they observed that both V oc and I sc get enhanced by ∼ 50%.…”

“…In recent years, high output TENGs have been demonstrated using the patterned surface or nanowires of polymer materials such as polydimethylsiloxane (PDMS) or Kapton ,. Evidently, maximization of the output of the TENG devices should involve, apart from the contact area, the type of material, surface functionalization, and surface morphology as the key factors. Understandably, significant efforts have been devoted to design and fabricate a high‐performance TENG based on these factors.…”

Triboelectric Nanogenerator Based on Biocompatible and Easily Available Polymer Films

We have fabricated robust triboelectric nanogenerators (TENGs) employing different polymer films which are biocompatible and easily available. The combination of polyurethane and PTFE layers is seen to provide the highest TENG parameters with an open circuit peak-to-peak output voltage of~33.5 V and a current value of 27.4 mA with a gentle tapping force of 0.33 N. The topography of the film surface has been characterized using atomic force microscopy in conjunction with image analysis. We find a very good, albeit non-linear, correlation between the TENG electrical output and the surface roughness. Our studies do not support any relation between the permittivity of the medium and the TENG output. Employing cellulose acetate and Kapton as the triboelectric layers, we have constructed a simple force sensor, whose output is seen to be highly linear over a large range of force varying from 0.24 to 5.2 N, and a significantly high output of 1.5 V/N.[a] Dr.

“…Under a rotation speed of 1600 rpm, the hybrid device generated 5 V on an open‐circuit and a short‐circuit current of 2.5 mA. Shin et al fabricated a polydimethylsiloxane (PDMS)–based TENG that is capable of harnessing irregular mechanical energy. The TENG was able to deliver a maximum V oc of 6.3 V and I sc of 0.635 μA.…”

Summary This paper reports a thermomagnetic generator based on the magneto‐caloric effect of Gadolinium to scavenge low‐grade thermal energy and its eventual conversion into electrical energy. Gadolinium is one of the distinct materials whose Curie temperature is nearly room temperature. For this reason, a Gadolinium‐based thermomagnetic engine offers enormous possibilities to harness available waste heat from the industries. In this work, the performance of an electromagnetic generator (EMG) coupled with a triboelectric nanogenerator (TENG) was experimentally investigated as it is driven by a thermomagnetic engine exploiting low temperature waste heat. At the temperature difference of 46.5°C between the hot and cold water jets, the thermomagnetic engine produced an average rotational speed of 263 ± 1.5% rpm and a mechanical output power of 76.38 ± 0.5% mW. At the aforementioned rotational speed, the hybrid generator delivered a rectified peak voltage of 15.34 V on an open‐circuit, a short‐circuit current of 20.1 mA, and the largest power output, 12.1 mW, at a 120 Ω load. It was demonstrated that the proposed energy harvester could light dozens of light‐emitting diodes or power a digital thermometer. It is feasible that the proposed thermomagnetic generator can be utilized as an effective power source for various applications.
