Electrochemical sensors are widely known sensing devices. The electrochemical sensors are used in application areas including health care, agriculture, and water quality monitoring. Screen printed paper based/ceramic electrodes are 2D and can’t be used for in-situ applications. The electrochemical sensors generally comprise multiple electrodes.
This invention provides a 3-D electrochemical sensor with 3-dimensional Working, Counter and reference electrodes in a predefined 3-D structure for in-situ soil moisture sensing.

In the realm of electrochemical sensors, existing technologies often face limitations in effectively sensing various substances in different environments. Traditional sensors, like those made from screen-printed materials, are mostly two-dimensional and struggle with applications requiring in-situ measurements, such as soil analysis or real-time environmental monitoring. These sensors are typically unable to provide accurate and reliable data in dynamic settings due to their flat structure and material constraints. The present invention addresses these challenges by introducing a novel electrochemical sensor with three-dimensional electrodes. This innovation allows for enhanced sensing capabilities in complex environments like soil, where traditional sensors fall short. By incorporating 3D structures and specialized coatings, this sensor aims to improve accuracy and reliability in measuring a wide range of substances, thereby offering a robust solution for practical and real-world sensing applications.
