“…On the other hand, PVP nanofibers are selected as the other frictional mat due to their strong ability to donate electrons [34]. Furthermore, the rough and porous surfaces of the nanofibers extend the contact area between the frictional materials which results in an increment of the triboelectric effect [35]. The technique of electrospinning was used to prepare both layers of nanofibers due to its low cost, versatility and simplicity for the fabrication of nanofibers using a wide variety of triboelectric mats [36].…”

Since 2012 there has been a rapid rise in the development of triboelectric nanogenerators due to their potential applications in the field of energy harvesting and self-powered sensors for vibrations, accelerations, touches, pressures and other mechanical motions. This study suggests a novel triboelectric nanogenerator based on the interaction between polyvinylidene fluoride and polyvinylpyrrolidone submicron fibers. Polyvinylpyrrolidone is introduced as a new material for the TENG because of its tendency of losing electrons easily, while polyvinylidene fluoride is selected for its strongelectron attracting ability. Electrospinning is suggested as a fabrication method for the nanofibers due to its simplicity, versatility and low-cost. Furthermore, the paper explores the possibility to use this triboelectric nanogenerator as a self-powered pressure sensor. For this purpose, the nanogenerator is subjected to dynamic mechanic analysis which produces controlled pressure forces applied with a certain frequency. This is the first work to suggest the use of dynamic mechanical analyzer to study the relation between the applied mechanical stimulus and the electric responses of the triboelectric nanogenerator. Eventually the sensitivity of the nanogenerator to different pressures is analysed. A directly proportional relationship is found between the pressure applied and the resultant voltage and current amplitudes. The developed nanogenerator reacts to pressure in real time and as a sensor it exhibits a very high sensitivity and low experimental error for repeated measurements. The main contributions of this study are the development of a novel nanogenerator based on the triboelectric effect between polyvinylidene fluoride and polyvinylpyrrolidone electrospun fibers and the investigation for its potential use as a selfpower pressure sensor. Eventually, the paper explores the advantages of dynamic mechanical analyzer for pressure analysis.

“…In summary, the fabrication process of the sensor is very simple and does not require expensive materials or technologies, which makes the process cheap and easy to perform [27,28]. Moreover, the process can be easily upgraded for large-scale production, which suggests a promising method for fabrication of such sensors on an industrial scale using a low-cost technology.…”

Bird strikes, hailstone impacts, and other type of mechanical collisions are quite frequent for a number of crucial and important structures, including aircrafts, wind turbines, bridges and other composites structures. These impacts harm the integrity of the composite laminates used in their structures which results in delamination and other failures which reduces their overall lifetime. Hence, the prediction of the damage caused by these impacts can be used to assess assessing the integrity of the composite structures.
