Long-term monitoring of organic pollutants in the soil is a major environmental challenge. We propose to meet this issue by the development of a polymer dedicated to selectively react with H2S, coating surface acoustic wave transducers designed as passive cooperative targets with the compound, and probing their response using Ground Penetrating RADAR, thus providing the capability to monitor the presence of H2S in the subsurface environment. The selectivity is brought by including lead(II) cation in a reticulated polymer matrix which can be deposited as a thin layer on a surface acoustic wave sensor. We demonstrate a signal enhancement mechanism in which water absorption magnifies the signal detection, making the sensor most sensitive to H2S in an underground environment saturated with moisture.

通过表面声波无源无线传感器对地面H2S的检测，该传感器被探地雷达穿透。
长期监测土壤中的有机污染物是一项重大的环境挑战。我们建议通过开发专用于与H2S选择性反应的聚合物，涂覆被设计为与该化合物无源协作目标的表面声波换能器并使用探地雷达探测其响应的方法来解决此问题，从而提供监视存在的能力地下环境中的硫化氢 通过在网状聚合物基质中包含铅（II）阳离子来实现选择性，该基质可以薄层形式沉积在声表面波传感器上。我们演示了一种信号增强机制，其中吸水会放大信号检测范围，从而使传感器在充满湿气的地下环境中对H2S最敏感。
