Abstract

Disposable devices designed for single and/or multiple reliable measurements over a short duration have attracted con-siderable interest recently. However, these devices often use non-recyclable and non-biodegradable materials and wasteful fabrication methods. Herein, we present ZnO nanowires (NWs) based degradable high-performance UV photodetectors (PDs) on flexible chitosan substrate. Systematic investigations reveal the presented device exhibits excellent photo response, including high responsivity (55 A/W), superior specific detectivity (4x10 14 jones), and the highest gain (8.5x10 10 ) among the reported state of the art biodegradable PDs. Further, the presented PDs display excellent mechanical flexibility under wide range of bending conditions and thermal stability in the measured temperature range (5–50 °C). The biodegradability studies performed on the device, in both deionized (DI) water (pH≈6) and PBS solution (pH=7.4), show fast degradability in DI water (20 mins) as compared to PBS (48 h). These results show the potential the presented approach holds for green and cost-effective fabrication of wearable, and disposable sensing systems with reduced adverse environmental impact.

基于ZnO纳米线的可降解高性能光电探测器，用于环保绿色电子产品

专为短时间内的单次和/或多次可靠测量而设计的一次性设备最近引起了相当大的兴趣。然而，这些装置通常使用不可回收和不可生物降解的材料和浪费的制造方法。在此，我们在柔性壳聚糖衬底上制备了基于ZnO纳米线(NWs)的可降解高性能紫外光电探测器(pd)。系统研究表明，该器件具有优异的光响应性能，包括高响应度(55 A/W)，优越的比探测率(4 × 10 14琼斯)和最高的增益(8.5 × 10 10)。此外，所述pd在大范围弯曲条件下表现出优异的机械灵活性和在测量温度范围(5-50°C)内的热稳定性。在去离子水(pH≈6)和PBS溶液(pH=7.4)中进行的生物降解性研究表明，与PBS溶液(48小时)相比，该装置在去离子水(20分钟)中可快速降解。这些结果表明，该方法具有绿色和经济高效制造可穿戴式一次性传感系统的潜力，减少了对环境的不利影响。
