An enhanced power harvesting from woven textile using piezoelectric materials

Abstract

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. Moreover, we report the effects of various substrates and investigates the sticking of these substrates on the characterization of the piezoelectric material.

Flexible Smart Material With Excellent Energy Harvesting<strong> </strong>

“…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.…”

Flexible Smart Textile Coated by PVDF/Graphene Oxide With Excellent Energy Harvesting Toward a Novel Class of Self-Powered Sensors: Fabrication, Characterization and Measurements

“…Of the four significant crystalline phases α, β, γ and δ [69-73] (Fig. 8); the electro-active β phase is the most used for detection, actuation [74,75] and micro-generation applications [71,76,77]. Various methods of crystallization of the β phase have been studied, in particular melt casting [82], solution deposition [78,79], spin coating [79,80] and phase inversion [81,82].…”

“…In addition, the integration into the PVDF matrix of functional nanofillers such as barium titanate, zirconium titanate (PZT), carbon nano fillers, graphene oxide (GO), titanium (TiO2) is an effective and cost-effective method for the induction of β-polymorph. [12][13][14] The integration of intelligent materials in textile systems provides the opportunity to create textiles with a new type of behaviour and function; Power generation or storage [15], human interface elements [16], radio frequency (RF) functionality, or assistive technology [17] could be the active functionality. Wearable sensors provide a sustainable solution through leg movements for energy harvesting technologies, and other research teams are exploiting body heat.…”

Improvement in energy conversion of electrostrictive composite materials by new approach via piezoelectric effect: Modeling and experiments

“…At the present time, advances in this domain of smart materials suggested an investigation about their capabilities of the use of these materials as energy converters. [11][12][13][14] Electroactive polymers are a novel class of rising materials, containing ionic polymers (IPMC, ionic gels, …) and electronics polymers (piezoelectric, dielectric, etc.). They are usually used as actuators for artificial muscles, in robotics or mechatronics.…”

“…This energy harvesting can be produced only if adjusted materials of conversion and effective process of extraction of energy are available. At the present time, advances in this domain of smart materials suggested an investigation about their capabilities of the use of these materials as energy converters 11‐14 …”
