Societal adoption of the Internet of Things (IoT) technologies has been both rapid and ubiquitous, with the number of devices predicted to be in use expected to reach more than 29 billion by 2030. These technologies have wide-ranging applications, in both industrial and consumer market places. This rapid growth of the IoT market is driving the need for additional, more functional and reliable sensors that can operate and communicate on IoT networks. Sensor devices typically employ a variety of transducer methods such as optical, electrical, and/or microelectromechanical (MEMS)-based detection mechanisms. However, optical and MEMS sensor devices require their transduced signals to be Electrochemical sensors and systems have been utilised and simulated theoretically throughout the years, however, the majority of this work has been undertaken using quiescent conditions.
