“…The steady-state temperatures were reached for all samples in o60 s, thus demonstrating a faster response 41,42 than graphenebased electro-thermal films, which reaches T B 42 1C when 60 V is applied for 2 min. 43 In all our GNP fabrics, the temperature remained stable on constant voltage applied and then returned to room temperature (T B 20 1C) after about 60 s when power was turned off.…”

“…The heater with a sheet resistance of 3.7 Ω/sq and transmittance of 82.5% had steady-state temperature of 145 °C. As compared with other flexible transparent heaters in the literature studies, the heater based on nanosoldered Ag NWs had both high heating rate (4.8 °C/s) and power density (0.8 W/cm 2 ). ,,− Thus, the heater could reach a high steady-state temperature of 145 °C at a low input voltage of 6 V with a fast response time of 30 s. For the heating rate, it is proportional to the accumulated heat in film heater, while the accumulated heat is determined by the difference value between the generated heat and dissipated heat. For best practice, it is preferred to have high heating rate and low power density, in other words, smaller dissipated heat is better.…”

Silver nanowires (Ag NWs) are key materials to fabricate next-generation flexible transparent electrodes (FTEs). Currently, the applications of Ag NWs are impeded by the large wire−wire contact resistance. Herein, a selflimited nanosoldering method is proposed to reduce the contact resistance by epitaxially depositing silver nanosolders at the Ag NW junctions, which have a negligible effect on the optical transparency, while decreasing the sheet resistance of the Ag NW film from 18.6 to 7.7 Ω/sq at a transmittance of 90%. In addition, the deposited nanosolders at the junctions remarkably improve the electrical and mechanical stabilities of the Ag NW electrodes. Notably, this simple nanosoldering process can be rapidly conducted under room temperature and ambient conditions and is free of any technical support or specific equipment. This technique is easily applied to the nanosoldering of 210 × 297 mm FTEs. Based on these FTEs, a high-performance flexible transparent heater with a sheet resistance 3.7 Ω/sq at a transmittance of 82.5% is constructed. Because of the high heating rate (4.8 °C/s), the heater can produce uniform heating (145 °C) at a short response time (30 s) and low input voltage (6 V).

“…The stability of the heating film that operated at low voltage is reported in our previous publication. 24 Nevertheless, due to the AgNWs that embeded in PI film is unstable at high temperature, noise in its thermal performance is observed at the voltage higher than 5 V (Figure 2d). The impressive thermal behavior affords the electronic a constant operating temperature (e.g., 45 °C) with low power consumption; in addition, the desirable optical transmissive allows most of the visible light that is generated by the EL plate to beam through the transparent heating film to reach the filmlike nanosensor for enhancing the sensing behavior.…”

Telemedicine provides an attractive vision for tele-monitoring human health conditions and, thus, offers the opportunity for timely preventing chronic disease. A key limitation of promoting telemedicine in clinic application is the lack of a noninvasive med-tech and effective monitoring platform, which should be wearable and capable of high-performance tele-monitoring of health risk. Here we proposed a volatolomics-based telemedicine for continuously and noninvasively assessing human health status through continuously tracking the variation of volatile markers derived from human breath or skin. Particularly, a nanosensor-based flexible electronic was specifically designed to serve as a powerful platform for implementing the proposed cost-effective healthcare. An all-flexible and highly packed makeup (all functional units were integrated in a 2*2*0.19 cm3 plate) enables an electronic, compact configuration and the capability of resisting negative impact derived from customers’ daily movement. Notably, the nanosensor-based electronic demonstrates high specificity, quick response rate (t 90% = 4.5 s), and desirable low detection limit (down to 0.117 ppm) in continuous tele-monitoring chronic-disease-related volatile marker (e.g., acetone). Assisted by the power saved light fidelity (Li-Fi) communicating technology, a clinic proof on the specifically designed electronic for noninvasively and uninterrupted assessing potential health risk (e.g., diabetics) is successfully implemented, with the accuracy of around 81%. A further increase in the accuracy of prewarning is predicted by excluding the impact of individual differences such as the gender, age, and smoking status of the customer. These promising pilot results indicate a bright future for the tailor-made nanosensing-device-supported volatolomics-based telemedicine in preventing chronic diseases and increasing patients’ survival rate.
