“…As studied for the case of thermal annealing of CuNWfilms under ambient air in an earlier work, this failure can be explained by a temperature-induced oxidation that becomes pronounced for temperatures above 150 ∘ C [27]. This degradation mechanism has also been reported by Zhai et al for CuNW-films under current flows that correspond to temperatures above 80 ∘ C [83]. The failure of the CuNW-film goes along with a steep increase in resistance that is shown in Figure 7(d) for the AgNW-and the CuNW-based heaters.…”

We review and extend the numerous polyol-based synthesis protocols and postdeposition treatments that have been reported for silver nanowires (AgNWs). After tailoring substantial process parameters such as the process time, temperature as well as the stirring speed, the polyvinylpyrrolidone (PVP) to silver nitrate (AgNO 3 ) ratio, and the type of PVP, a high mean aspect ratio of 800 could be achieved. Interestingly, the addition of a small portion of potassium chloride (KCl) not only leads to a reduction in diameter but also extremely enhances the nanowire dispersion and its stability. This effect is attributed to the role of KCl, which, along with PVP, acts as a cocapping agent. Furthermore, sprayed AgNW and copper nanowire (CuNW) films were tested as transparent heaters. The AgNWs could be operated at a power density of at least 0.72 W/cm 2 , which corresponds to a temperature of 213 ∘ C, whereas the CuNWs failed at a power density and temperature of 0.4 W/cm 2 and 150 ∘ C, respectively. Interestingly, the degradation of AgNWs shows a step-wise behavior and is mainly dominated by fragmentation, while the CuNWs are gradually oxidized.

Powered by market hype, trends among youth, and enormous funds, wearable technology has propelled itself as one of the most discussed topics in the field during past few years. A number of different companies representing all throughout the world have already entered into the market with hundreds of different products like smart watches, fitness trackers, smart garments, and even different smart medical attachments.Together with the evolution of digital health care, the wearable electronics field has evolved rapidly during the past few years and is expected to be expanded even further within the first few years of the next decade. As the next stage of wearables is predicted to move toward integrated wearables, nanomaterials and nanocomposites are in the spotlight of the search for novel concepts for integration. In addition, the conversion of current devices and attachment-based wearables into integrated technology may involve a significant size reduction while retaining their functional capabilities. Nanomaterialbased wearable sensors have already marked their presence with a significant distinction while nanomaterial-based wearable actuators are still at their embryonic stage. This review looks into the contribution of nanomaterials and nanocomposites to wearable technology with a focus on wearable sensors and actuators.

The high-quality flexible graphene thin films have been fabricated by the nondestructive rubbing method. The film exhibits an excellent photothermal conversion ability after oxygen plasma treatment and multiple mechanical bending. The temperature can be increased to 47.4°C even under a low laser irradiation power of 240mW with a decent heating rate of 0.3°C/s, and photothermal conversion efficiency reaches as high as 28%. The steady-state temperature can be precisely tuned by changing the laser power. These excellent results indicate graphene-based photothermal elements holding great promise for practical applications.
