“…This paper has investigated the development of a novel energy harvesting systems, which are a clean and durable solution, based on the thin film PVDF sticking on flexible substrates such as fabrics. The smart structure shows greater piezoelectric and dielectric properties compared to our previous work [45][46][47][48][49][50]. These properties are explored and discussed in this paper.…”

The field of power harvesting has experienced significant growth over the past few years due to the ever-increasing desire to produce portable and wireless electronics with extended lifespans. The present work aims to introduce an approach to harvesting electrical energy from a mechanically excited piezoelectric element and investigates a power analytical model generated by a smart structure of type polyvinylidene fluoride(PVDF) that can be stuck onto fabrics and flexible substrates, although we report the effects of various substrates and investigates the sticking of these substrates on the characterization of the piezoelectric material.

“…Tang et al proposed a novel wind energy harvester using a wind vane and PVDF film to convert the multidirectional wind energy in the grid into electricity [28]. Eddiai et al has been researched to provide a framework to develop an innovative energy-harvesting technology that collects vibrations from the environment and converts them into electricity to power a variety of sensors [29]. The lowflow compressed air condition has always existed in pneumatic systems, but this energy is often overlooked and wasted.…”

Low-flow air has been attracted many researchers which can be transformed into electric energy by the piezoelectric materials. A flow amplifier device can be used to increase the performance of piezoelectric energy harvester excited by low-flow air. The Coanda effect theory has been analyzed based on the fast-moving air. To analyze the effect of the amplifier device and verify the feasibility of the proposed cantilevered PVDF energy harvester, we employed finite element simulation to analyze the flow distribution of the amplified flow air. Then the stress and potential distribution of PVDF film have been analyzed. A prototype of the cantilevered PVDF energy harvester is tested with different variables such as input air flow, pressure and cycle time. The test results show that the output voltage increases with increasing input air flow. The output voltage decreases slightly with increasing input cycle time. The peak voltage decreases as the distance between the prototype and the excitation source increases. Importantly, the output voltage for the amplified airflow is about three-times that of the non-amplified air flow. The maximal output voltage and power are 12.80 V and 19.89 µW at the pressure of 0.2 MPa and a flow rate of 200 L/min, respectively. INDEX TERMS Coanda effect, PVDF energy harvester, amplified air flow, simple harmonic oscillation.

“…PENGs have the advantages of high sensitivity, real-time sensing, and good flexibility, and can be used as self-powered skin sensors by using flexible materials. The reported skin PENGs are mostly based on conventional piezoelectric materials including zinc oxide (ZnO) nanowires, PVDF nanofibers, and lead zirconate titanate (PZT) powders [36,53,57,58,59,60,61,62]. In addition, some materials which have a piezoelectric effect at the nano scale but not in a bulk state have also been used in skin PENGs, such as boron nitride (BN) [63,64].…”

Self-powered skin sensors have attracted significant attention in recent years due to their great potential in medical care, robotics, prosthetics, and sports. More importantly, self-powered skin sensors do not need any energy-supply components like batteries, which allows them to work sustainably and saves them the trouble of replacement of batteries. The self-powered skin sensors are mainly based on energy harvesters, with the device itself generating electrical signals when triggered by the detected stimulus or analyte, such as body motion, touch/pressure, acoustic sound, and chemicals in sweat. Herein, the recent research achievements of self-powered skin sensors are comprehensively and systematically reviewed. According to the different monitoring signals, the self-powered skin sensors are summarized and discussed with a focus on the working mechanism, device structure, and the sensing principle. Based on the recent progress, the key challenges that exist and the opportunities that lie ahead are also discussed.
