Abstract

The miniaturization of electronic devices and the rapid advancements in fabrication technologies has promoted the field of wearables electronics. However, the power requirement imposes a considerable energy consumption burden on...

Solar-assisted all-solid supercapacitors using composite nanostructures of ZnO nanowires with GO and rGO

“…In particular, the use of solar energy as a renewable energy source has become a growing concern to diminish the dependence on fossil fuels. [1][2][3][4][5] Nowadays, several technologies for energy conversion and storage such as photovoltaic (PV) solar cells, 6 photoelectrochemical (PEC) cells, [7][8][9][10] Li-ion batteries, 11 PEC redox-flow batteries, 12 and supercapacitors (SC) 13 have been developed to meet the energy demand. In particular, in the last few years, supercapacitors have attracted significant attention due to their low-cost, safe operation, fast charge-discharge cycles, high power density, and cyclic stability.…”

Flexible optoelectronic sensors: status and prospects

“…In addition, a fabric is usually of high porosity (i.e., good air permeability), and thus more suitable for wearable applications where comfort must be considered. 98 The simplest strategy is to directly use conductive fabrics as substrates. For example, Shen et al applied carbon cloths to deposit TiO 2 (Fig.…”

“…Compared to planar devices that are bendable via a single axis, a fiber that is long and thin can have highly reduced bending stiffness due to its fourth power correlation to the diameter (eqn (1)). 98 In general, there are two ways of fabricating optoelectronic fibers: (1) direct thermal drawing of multimaterial fibers; (2) coating of functional materials on fibers. The former process starts with optical fiber fabrication, starting with a multimaterial macroscopic preform in which bulk materials are arranged at prescribed and well-defined positions/geometry (Fig.…”

Semiconductor Multimaterial Optical Fibers for Biomedical Applications

“…All examples of nonlinear behavior in semiconductor optical fibers have been linked with centrosymmetric crystal systems, with the major portion associated with the silicon fiber framework [ 93 ]. The transformation of optical power into electrical power is the fundamental process that underpins the majority of semiconductor-detecting or energy-collecting OE devices [ 170 ]. This transformation is a significant advantage of the semiconductor OE fiber platform over other similar technologies.…”
