“…Flexible and stretchable structures in TENG−SC systems have become increasingly important in the development of wearable electronics and portable devices, as they contribute to mechanical durability, adaptability, and user comfort [ 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 ]. Yang et al focus on creating a fully stretchable self−charging power unit (FS−SCPU) by integrating a micro−supercapacitor (MSC) and a TENG using oxidized single−walled carbon nanotube (Ox−SWCNT)/polymer electrodes [ 50 ].…”

The growing demand for sustainable and efficient energy harvesting and storage technologies has spurred interest in the integration of triboelectric nanogenerators (TENGs) with supercapacitors (SCs). This combination offers a promising solution for powering Internet of Things (IoT) devices and other low−power applications by utilizing ambient mechanical energy. Cellular materials, featuring unique structural characteristics such as high surface−to−volume ratios, mechanical compliance, and customizable properties, have emerged as essential components in this integration, enabling the improved performance and efficiency of TENG−SC systems. In this paper, we discuss the key role of cellular materials in enhancing TENG−SC systems’ performance through their influence on contact area, mechanical compliance, weight, and energy absorption. We highlight the benefits of cellular materials, including increased charge generation, optimized energy conversion efficiency, and adaptability to various mechanical sources. Furthermore, we explore the potential for lightweight, low−cost, and customizable cellular materials to expand the applicability of TENG−SC systems in wearable and portable devices. Finally, we examine the dual effect of cellular materials’ damping and energy absorption properties, emphasizing their potential to protect TENGs from damage and increase overall system efficiency. This comprehensive overview of the role of cellular materials in the integration of TENG−SC aims to provide insights into the development of next−generation sustainable energy harvesting and storage solutions for IoT and other low−power applications.

“…The power output may be greatly affected if the conductivity of composite triboelectric electrodes is seriously degraded, elongated, or deformed, Zhong et al proposed an omnidirectional stretchable triboelectric fabric based on liquid metal (LM) electrodes and Ecoflex ( Figure 3 h) [ 41 ]. The ultimate tensile strength of the triboelectric fabric is 660%, the resistance can be maintained at 0.678 Ω under 200% tensile strength, and the dielectric constant was improved by joining TiO 2 particles into Ecoflex.…”

There is an increasing need for structural flexibility in self-powered wearable electronics and other Internet of Things (IoT), where adaptable triboelectric nanogenerators (TENGs) play a key role in realizing the true potential of IoT by endowing the latter with self-sustainability. Thus, in this review, the topic was restricted to the adaptive design of TENGs with structural flexibility that aims to promote the sustainable operation of various smart electronics. This review begins with an emphatical discussion of the concept of flexible electronics and TENGs, and continues with the introduction of TENG-based self-powered intelligent systems while placing the emphasis on self-powered flexible intelligent devices. Self-powered healthcare sensors, e-skins, and other intelligent wearable electronics with enhanced intelligence and efficiency in practical applications due to the integration with TENGs are illustrated, along with an emphasis on the design strategy of structural flexibility of TENGs and the associated integration schemes. This review aims to cover recent achievements in the field of self-powered systems, and provides information on how flexibility or adaptability in TENGs can be adopted, their types, and why they are required in promoting advanced IoT applications with sustainability and intelligence algorithms.

“…However, due to the hard and brittle physical properties of PZT and the low piezoelectric properties of PVDF, these are not attractive materials for most e-textiles applications. In addition to piezoelectric generators, textile based triboelectric generators have been used to harvester mechanical energy [12][13][14]. Ye et al demonstrated a triboelectric generator consisting of silk fibre, polytetrafluoroethylene fibre and stainless steel fibre, which can be driven by friction between the arm and the body [15].…”

This paper reports the lamination of two thin fluorinated ethylene propylene (FEP) films onto the back and front surfaces of a conventional textile forming a sandwich structure which creates a textile-based ferroelectret. In this work, we study the effect of the physical properties and dimensions of the textile on the piezoelectric properties and energy harvesting performance of the ferroelectret. Five different fabrics with different thicknesses and Young’s modulus were used to form textile based ferroelectret harvesters. Thinner textiles result in increased piezoelectric properties of the fabricated FEP textile ferroelectret. The highest measured stable maximum piezoelectric coefficient d33 of 987 pC/N was achieved by the thinnest silk textile FEP ferroelectret. The energy harvester based on the FEP-silk textile ferroelectret generates a peak output power density of 2.26 µW/cm2. The textile ferroelectret can charge a 10 µF capacitor used to store the harvested energy to 3.2 V in 40 seconds. This corresponds to an average output power of 1.07 µW when subjected to compressive pressures of 30 kPa applied at a frequency of 1Hz with a 90 MΩ loading resistance.
