Since the invention of fully synthetic plastic in the 1900s, plastics have been extensively applied in various fields and represent a significant market due to their satisfactory properties. However, the non-biodegradable nature of most plastics has contributed to the accumulation of plastic waste, which poses a threat to both the environment and living beings. Given this, biodegradable polymers have emerged as eco-friendly substitutes for non-biodegradable polymers, and standard test methods have been established to evaluate polymer biodegradability. Technological advancement and the weaknesses of conventional test methods drive the invention of sensors that enable real-time monitoring of biodegradability. Besides, biodegradable polymers have been utilized to make sensors with different functionalities. Given this, the current paper is the first to compare and contrast sensors capable of identifying biodegradable polymers. The detection using sensors represents an innovative perspective for real-time monitoring of biodegradability. Besides, sensors made from biodegradable polymers are included, and these sensors are of different types and show various applications. Finally, the challenges associated with developing these sensors are described to advance future research.
自 20 世纪全合成塑料发明以来，由于其满意的性能，塑料已广泛应用于各个领域，并具有较大的市场。然而，大多数塑料不可生物降解的性质导致了塑料废物的积累，这对环境和生物都构成了威胁。有鉴于此，可生物降解聚合物已成为不可生物降解聚合物的环保替代品，并且已经建立了标准测试方法来评估聚合物的生物降解性。技术进步和传统测试方法的弱点推动了能够实时监测生物降解性的传感器的发明。此外，可生物降解聚合物已被用于制造具有不同功能的传感器。因此，本文首次比较和对比了能够识别可生物降解聚合物的传感器。使用传感器进行检测为实时监测生物降解性提供了一个创新的视角。此外，还包括了由可生物降解聚合物制成的传感器，这些传感器有不同的类型，并显示出各种应用。最后，描述了开发这些传感器所面临的挑战，以推进未来的研究。
