Study of Ammonia and Humidity Sensor Based on Conductive Polymers and Its Composites [PDF]
, 2016 环境中的气体和湿度条件会影响人们的生活和工业生产，因而需要研制响应灵敏度高、可靠性优异、长期稳定性好的气体和湿度传感器来进行检测。目前的气体和湿度传感器主要是以金属氧化物和有机高分子为敏感材料。然而基于金属氧化物的传感器工作温度高，基于有机材料的传感器稳定性较差，均无法满足低功耗、低维护成本传感系统的要求。因此本文通过具有p-n异质结的金属氧化物/交联导电聚合物复合材料作为室温气体传感器的敏感材料提高其传感性能；另外以新型的聚电解质--绿色无污染的聚离子液体--为湿度传感器的敏感材料，制得了全湿度范围 ...

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, EarlyView.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

Rare Metals, EarlyView.ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...

World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Study of GHz Surface Acoustic Wave Humidty Sensor Using Nanostructured Materials [PDF]
, 2016 随着物联网应用的不断扩展，需要大量传感器节点组成无线传感网络以实现未来万物互联的目标。其中，湿度测量器件在智能家居、气象、工业控制等领域是最为广泛和基础的传感器节点。为了实现无线传感网络，现有的电阻、电容型传感器件需要独立的电源系统持续供电，而在电池容量有限的条件下，器件需要采用占空比方式工作，即在高功耗的传感工作状态之间加入待机模式，以减小传感器节点的总功耗。由于待机模式的存在，无法对整个环境状态进行实时、无缝的检测，且由于构成节点的传感元件一般属于相对高功耗的器件，电池寿命始终有限。声表面波 ...
