The demand of flexible energy storage devices for portable and wearable electronics has become increasingly urgent due to the rapid development of microelectronic products, wearable devices, and smart skin. [1][2][3][4][5][6] Some of the most effective and practical technologies for electrochemical energy conversion and storage are batteries, fuel cells, and supercapacitors. [7][8][9][10][11][12][13][14][15] Among them, supercapacitors (SCs) have attracted intensive attentions due to their high power density and long lifecycle. [9,13,[16][17][18] The energy storage is performed by ion adsorption or fast surface redox reaction at the interface between electrodes and electrolyte. Moreover, all-solid-state microsupercapacitors (MSCs) can greatly facilitate the development The graphene with 3D porous network structure is directly laser-induced on polyimide sheets at room temperature in ambient environment by an inexpensive and one-step method, then transferred to silicon rubber substrate to obtain highly stretchable, transparent, and flexible electrode of the all-solidstate planar microsupercapacitors. The electrochemical capacitance properties of the graphene electrodes are further enhanced by nitrogen doping and with conductive poly(3,4-ethylenedioxythiophene) coating. With excellent flexibility, stretchability, and capacitance properties, the planar microsupercapacitors present a great potential in fashionable and comfortable designs for wearable electronics.

“…To transform various mechanical energies, researchers have developed varied structures of TENGs, such as arch-shaped, spring-supported, and cantilever-based. [24][25][26] Output performances The output performance of the TENG can be determined by measuring open-circuit voltage (V OC ), SC current (I SC ), and power density. A typical feature of the TENG is a high voltage and a low current, which can be explained both physically and mathematically.…”

The triboelectric nanogenerator (TENG) as a new power-generation technology was reported by Wang and co-workers in 2012. Because of its great potential for scavenging mechanical energy from living environment and sustainably driving portable devices, many researchers have developed various methods to improve output performances of TENG. In this paper, we review the progress in TENG made as flexible power sources by integrating flexible materials and stretching structures, especially for the applications of flexible electronics. For optimizing performances of TENG, the structural designs, material selections, and hybrid energy cells are presented. The reported TENG as flexible power sources has the potential applications in lighting up light emitting diodes (LEDs), powering sensors, and monitoring biomechanical motions.

“…221 This is claimed to be the first prototype of a wearable device that can gather mechanical energy from human motion. The FTENG was fabricated by coating PDMS on carbon fiber electrodes as one of the triboelectric materials and PTFE as the second triboelectric layer with copper as the conducting film.…”

Wearable electronic devices represent a paradigm change in consumer electronics, on‐body sensing, artificial skins, and wearable communication and entertainment. Because all these electronic devices require energy to operate, wearable energy systems are an integral part of wearable devices. Essentially, the electrodes and other components present in these energy devices should be mechanically strong, flexible, lightweight, and comfortable to the user. Presented here is a critical review of those materials and devices developed for energy conversion and storage applications with an objective to be used in wearable devices. The focus is mainly on the advances made in the field of solar cells, triboelectric generators, Li‐ion batteries, and supercapacitors for wearable device development. As these devices need to be attached/integrated with the fabric, the discussion is limited to devices made in the form of ribbons, filaments, and fibers. Some of the important challenges and future directions to be pursued are also highlighted.
