“…At present, different analytical methods have been applied to detect H 2 O 2 , such as fluorescence, liquid chromatography, surface-enhanced Raman scattering, chemiluminescence, and electrochemistry . Among them, electrochemical technology has been widely applied due to its easy operation, high sensitivity, and high selectivity. − Traditional H 2 O 2 sensors usually use natural enzymes as the receptor, but the low stability and complex immobilization process limit their application .…”

Transition metal layered double hydroxide (LDH) nanomaterials have gained wide attention in the fields of supercapacitors, photocatalysis, and electrocatalysis due to their large specific surface area and eminent catalytic performance. In this work, hierarchical NiMn LDH nanosheet arrays were synthesized on flexible carbon cloth (CC) through a one-step hydrothermal reaction as a self-supporting electrode. For one thing, CC can efficiently prevent the aggregation of the NiMn LDH nanosheet and accelerate the electron transfer ability as a desired electric conductor. For another, the synthesized NiMn LDH nanostructures exhibited super electrocatalytic activity toward H 2 O 2 oxidation due to the large active surface area and the synergistic effect of Ni and Mn. Therefore, the nanostructured NiMn LDH on CC displays excellent sensing characteristic for H 2 O 2 with a broad linear range of 1−23,000 μM, a low detection limit of 0.26 μM, and a high sensitivity of 4108 μA mM −1 cm −2 . Moreover, the proposed sensor shows promising application prospects for detecting H 2 O 2 in frozen squid and dried tofu, demonstrating its importance in the food industry and food safety.

“…Some applications are shown in Figure 1. In terms of substrates, conventional silicon, and mature technologies have attained micro structures and ultrathin chips, which strengthen its flexibility (Lin C. C. et al, 2017;Navaraj et al, 2018). However, compared with this complicated process, the method for fabricating devices directly on the soft, bendable and skin-mounted polymer substrates, such as polyethylene (PE) and terephthalate (PET) is more advantageous.…”

Printed electronic technologies draw tremendous attention worldwide due to their ability to surpass the limitations of traditional high-cost electronics, based on rigid silicon, and the manufacturing of various devices on flexible substrates. As a critical component of flexible electronics, electrodes fabricated on soft, bendable, and stretchable substrates are of great importance. Based on the fabrication process, this paper classifies the mainstream technologies into two categories: top-down and bottom-up. Top-down technologies include physical evaporation methods, printing technologies and soft lithography, while bottom-up technologies involve polymer-assisted-metal-deposition methods and ion-exchange methods, respectively. In contrast to top-down technologies that transfer functional ink onto substrates directly, the bottom-up method achieves a great improvement in the adhesion between substrates and metal electrodes. In this paper, the challenges of top-down technologies, including cost, synthesis, and choice of ink for printing technologies, the limited choice of metal for bottom-up technologies and the mass production of these methods, are also discussed.

“…To achieve the flexibility of the Si substrate, the wet etching process was utilized to cut the thickness of the Si substrate. As the thickness of the Si substrate approached 30 μm, the substrate attained flexibility [ 41 ]. Traditionally, chemical-mechanical planarization (CMP) process has been utilized to slim the thickness of silicon substrate.…”

Photodetectors are widely applied in modern industrial fields because they convert light energy into electrical signals. We propose a printable silver (Ag) paste electrode for a highly flexible metal–semiconductor–metal (MSM) broadband visible light photodetector as a wearable and portable device. Single-crystal and surface-textured silicon substrates with thicknesses of 37.21 μm were fabricated using a wet etching process. Surface texturization on flexible Si substrates enhances the light-trapping effect and minimizes reflectance from the incident light, and the average reflectance is reduced by 16.3% with pyramid-like structures. In this study, semitransparent, conductive Ag paste electrodes were manufactured using a screen-printing with liquid-phase process to form a flexible MSM broadband visible light photodetector. The transmittance of the homemade Ag paste solution fell between 34.83% and 36.98% in the wavelength range of visible light, from 400 nm to 800 nm. The highest visible light photosensitivity was 1.75 × 104 at 19.5 W/m2. The photocurrents of the flexible MSM broadband visible light photodetector were slightly changed under concave and convex conditions, displaying stable and durable bending properties.
