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.
