The detection and classification of microplastics in the marine environment is a complex task that implies the use of delicate and expensive instrumentation. In this paper, we present a preliminary feasibility study for the development of a low-cost, compact microplastics sensor that could be mounted, in principle, on a float of drifters, for the monitoring of large marine surfaces. The preliminary results of the study indicate that a simple sensor equipped with three infrared-sensitive photodiodes can reach classification accuracies around 90% for the most-diffused floating microplastics in the marine environment (polyethylene and polypropylene).
在海洋环境中检测和分类微塑料是一项复杂的任务，需要使用精密且昂贵的仪器。本文提出了一项低成本、紧凑型微塑料传感器的初步可行性研究，该传感器原则上可以安装在浮标上，用于监测大面积的海洋表面。研究的初步结果表明，一个配备三个红外敏感光电二极管的简单传感器可以达到约 90%的分类准确率，用于分类海洋环境中最常见的漂浮微塑料（聚乙烯和聚丙烯）。
