Wearable and self-cleaning hybrid energy harvesting system based on micro/nanostructured haze film

Recent progress of triboelectric nanogenerators: From fundamental theory to practical applications

“…[69][70][71][72][73][74][75][76] To improve the energy harvesting capability, TENGs can be integrated with other energy harvesting technologies, so that various kinds of environmental energy could be scavenged simultaneously. [77][78][79][80] Chen et al developed a hybrid power textile which composed of a photovoltaic textile and fabric TENG, as illustrated in Figure 8F. 65 The hybrid textile can simultaneously harvest mechanical energy and solar energy, which hugely improved its output power and expanded its working circumstances.…”

Bio‐Derived Natural Materials Based Triboelectric Devices for Self‐Powered Ubiquitous Wearable and Implantable Intelligent Devices

“…However, long-term friction between triboelectric materials will lead to the surface pollution of the triboelectric layer by dust and contaminants, thus reducing the stability of the device. [229][230][231] To address this problem, Lee et al [229] developed a wearable transparent hydrogel-PDMS elastomer TENG, where the surface functionalization of PDMS by (heptadecafluoro-1,1,2,2-tetrahydrodecyl)trichlorosilane enables the self-cleaning ability for improving the sensitivity and stability of device performance.…”

“…It should be noted that a good water solubility also indicates the sensitivity of the devices to humidity, which might lead to poor device stability. [208,[229][230][231]320,321] To improve the mechanical reliability and stability of biomaterials based TENG devices, Pan et al demonstrated a TENG based on electrospun PLA nanofiber membrane, gelatin film and degradable metal Mg (Figure 4b). [208] The device showed no significant degradations after 15 000 circular contacts, due to the excellent elasticity and flexibility of PLA nanofiber membrane and gelatin film.…”

“…(1) At the level of materials, firstly, the mechanical stability and durability of the devices need to be significantly improved for fulfilling the requirements for long-term operations. [229][230][231]320,321,335] For instance, advances in designing and producing bio-derived materials with good self-healing ability and triboelectric properties could enable the cooptimization of the lifetime, stability, durability, and performance of the TENG devices. For example, Lee et al [321] proposed a method of using shape memory polymer (SMPs) as the triboelectric materials to improve the permanence and lifetime of TENG devices.…”
