A miniaturized chemical sensor is here described for the analysis of environmental pollutants (VOC: volatile organic chemicals). It is used for remote detection of formaldehyde (FA) fumes in the atmosphere, and is based on the redox reaction between FA and silver nitrate. The sensor is worn as a bracelet and the data acquired are transferred via a Bluetooth channel to a smartphone. A dedicated software transforms the signal from a grey to a color scale. The signal response has been assessed over low (20 to 120 ppb) as well as higher (1-15 ppm range) levels. The sensor has been applied to monitor potential FA fumes of some artwork in the Summer Palace in Beijing and the modifications induced by FA treatment on a precious Stradivarius violin. The performance of this novel sensor is compared with a commercial apparatus widely adopted, namely the Honeywell MultiRAE Lite wireless portable multi-gas monitor (pumped model).
本文介绍了一种用于分析环境污染物（挥发性有机化合物：VOC）的小型化化学传感器。它用于远程检测大气中的甲醛（FA）烟雾，基于FA与硝酸银之间的氧化还原反应。该传感器可作为手镯佩戴，采集到的数据通过蓝牙通道传输到智能手机。一款专用软件将信号从灰度转换为彩色标度。已在低浓度（20至120 ppb）以及高浓度（1 - 15 ppm范围）水平下评估了信号响应。该传感器已应用于监测北京颐和园一些艺术品潜在的FA烟雾，以及FA处理对一把珍贵的斯特拉迪瓦里小提琴所引起的变化。将这种新型传感器的性能与一种广泛采用的商业仪器，即霍尼韦尔MultiRAE Lite无线便携式多气体监测仪（泵吸式型号）进行了比较。
