TL;DR: Large-area and uniform three-dimensional (3D) β-Ni(OH)2 and NiO nanowalls were synthesized on a variety of rigid and flexible substrates via a simple aqueous chemical deposition process to develop highly sensitive, selective gas sensors and electrochemical sensors.

TL;DR: A novel self-powered photodetector based on reduced graphene oxide (rGO)/n-Si p-n vertical heterojunction with high sensitivity and fast response time with built-in electric field formed at the interface of n-Si and rGO film is presented.

TL;DR: In this article, a single CdS nanorod photodetector with a very low percentage of illumination intensity (2, 05 mW cm−2) under 450 nm, exhibited a high responsivity and reached at 123 × 104 A W−1 with the bias voltages of 2 V.

TL;DR: Here, NiO nanowalls decorated by SnO2 nanoneedles (NiO@SnO2) were in situ grown on ceramic microchips via a chemical bath deposition method to detect H2S instead of print- coating and slurry-coating methods.

TL;DR: A stimuli-responsive flexible sensor with a switchable dual-signal response (transparency and resistance) is achieved based on a multilayered Ag nanowire (AgNW)/SiOx /polydimethylsiloxane (PDMS) film that exhibits the dynamic visual feedback and the quantitative electrical signal, which provide a novel approach for developing smart flexible electronics.
