“…To maintain high conductivity under diverse deformations, metallic materials can be ingeniously designed into various patterns, such as serpentine-honeycomb structure [138]. Additionally, a range of nanostructured electrodes with excellent mechanical flexibility and electrical properties, including Ag NWs, graphene, and carbon nanotubes, have been extensively developed in flexible PDs [139][140][141].…”

Flexible photodetectors (PDs) have garnered increasing attention for their potential applications in diverse fields, including weather monitoring, smart robotics, smart textiles, electronic eyes, wearable biomedical monitoring devices, and so on. Notably, perovskite nanostructures have emerged as a promising material for flexible PDs due to their distinctive features, such as a large optical absorption coefficient, tunable band gap, extended photoluminescence (PL) decay time, high carrier mobility, low defect density, long exciton diffusion lengths, strong self-trapped effect (STEs), good mechanical flexibility, and facile synthesis methods. In this review, we first introduce various synthesis methods for perovskite nanostructures and elucidate their corresponding optical and electrical properties, encompassing quantum dots (QDs), nanocrystals (NCs), nanowires (NWs), nanobelts (NBs), nanosheets (NSs), single-crystal thin films, polycrystalline thin films, and nanostructured arrays. Furthermore, the working mechanism and key performance parameters of optoelectronic devices are summarized. The review also systematically compiles recent advancements in flexible PDs based on various nanostructured perovskites. Finally, we present the current challenges and future prospects for the development of perovskite nanostructures-based flexible PDs.

“…They found that the transparency and conductivity of the networks could be separately regulated by varying the mesh width and film thickness. Some research groups demonstrated a universal self-assembly method of ordered Ag nanowires by using the coffee-ring effect [13][14][15] . The AgNWs micromesh exhibited excellent transmittance of 86.6% and conductivity of 6 Ω/sq [16] .…”

The leaf veins with hierarchically interconnected network structures have great potential as self-assembly templates for transparent and flexible electrodes. In this paper, a liquid membrane ruptured assisted AgNWs self-assembly method was adopted to obtain conductive veins, which show a low sheet resistance of 3.6 /Ω❏ and a high transparency of 80.3%. The figure of merit of conductive veins was as high as 451Ω-1 and can be further increased by increasing the number of soaking because the light transmittance is immune to the AgNWs layer number. The veins maintained excellent electrical conductivity even after bending 10000 times at a 2 mm radius of curvature and exhibited excellent corrosion resistance under harsh conditions. Heaters based on the conductive veins are shown as application examples. A high temperature of 104 oC was achieved at a low voltage of 2 V, enough to heat cold water. Furthermore, pressure sensors based on the conductive veins were fabricated as examples of wearable devices. Human actions such as finger bending, wrist bending, elbow swing, throat swallowing, smile and walking can be monitored in real-time. The liquid film ruptured assisted nanomaterial self-assembly method is an effective strategy for the efficient preparation of conductive mesh, which can be extended to any substrates with mesh structure owing to its simplicity and universality.

“…To adapt to the natural environment, animals such as chameleon and octopus have gradually developed a unique function of skin color change after nature evolution. The thermochromic devices have been exploited to visualize the temperature stimulus with a color change for application in sensors , and displays, − which can be considered an effective solution to overcome the limitation of relying only on terminals with complicatedly physical connections and immensely enhance information interaction in the fields of military equipment, security systems, and human–machine interaction. In this work, inspired by the reversible color-change property of chameleon skin, a bioinspired stretchable and adhesive multimodal chromotropic e-skin system (MCES) consisting of adhesive polydimethylsiloxane (a-PDMS), conformal liquid metal (LM), thermochromic inks, and bare PDMS encapsulation layer was proposed (Figure ), which was capable of simultaneously detecting and distinguishing multi-stimuli of pressure, temperature, and strain through triboelectric, thermochromic, and capacitive effects with disparate perceptive signals.…”

It is highly desirable to construct a single-multimodal sensor that could synchronously perceive multiple stimuli without interference. Here, we propose an adhesive multifunctional chromotropic electronic skin (MCES) that can respond to and distinguish three different stimuli of stain, temperature, and pressure within the two-terminal sensing unit. The mutually discriminating "three-in-one" device converts strain into capacitance and pressure into voltage signals for a tactile stimulus response and produces visual color changes against temperature. In this MCES system, the interdigital capacitor sensor shows high linearity (R 2 = 0.998), and temperature sensing is realized via reversible multicolor switching bioinspired by the chameleon, showing attractive potential in visualization interaction. Notably, the energy-harvesting triboelectric nanogenerator in MCES can not only detect pressure incentive but also identify objective material species. Looking forward, these findings promise for multimodal sensor technology with reduced complexity and production costs that are highly anticipated in soft robotics, prosthetics, and human−machine interaction applications.
