Interdigital or interdigitated electrodes have been used as a cornerstone to form the design of the electrodes for quite some time. The prominent advantages of this type of design have led to its use in a variety of sectors in the field of science and technology. Among the different applications these sensors are employed for, the paper presents some of the significant works done in the field of biomedical, environmental, and industrial sectors. In these three sectors, sensors have been associated with different kinds of signal-conditioning circuits to process and transmit the data to the monitoring unit. Apart from the design, the processing material, structure and dimensions of the sensors have been largely varied according to the specific application for which the sensors have been employed. These differences diversify their performance in terms of efficiency and sensitivity. Some of the challenges faced by the current sensors have also been mentioned along with the remedial solutions.

叉指式或叉指式电极已经用作形成电极设计的基石已有一段时间了。这种设计的显着优势导致其在科学和技术领域的各个领域中得到使用。在这些传感器的不同应用中，本文介绍了在生物医学，环境和工业领域完成的一些重要工作。在这三个部分中，传感器已与不同种类的信号调节电路相关联，以处理数据并将数据传输到监视单元。除了设计之外，传感器的处理材料，结构和尺寸已经根据采用传感器的特定应用进行了很大的变化。这些差异使它们在效率和灵敏度方面的表现多样化。补救措施也提到了当前传感器面临的一些挑战。
