A sensor is a machine that measures physical input from its environment and transforms it into data that can be analysed by humans or machines.
To detect a physical phenomenon, a sensor is a device that produces an output signal.
Any device, module, machine, or subsystem that monitors its environment and provides data to other electronics—typically a computer processor—is a sensor in the broadest meaning.

Recent advancements in printing electrode devices for electrochemical sensors based on nanotechnology.
The most recent advances in screen, inkjet, and three-dimensional (3D) printing electrode technologies of various types, production methods, and applications are critically examined.
New printing electrode-based fabrication techniques for printed electrode materials have sparked the creation of printed electrode devices and systems, creating new opportunities for a variety of electrochemical applications.
By embedding and/or immobilising nano-structured materials, their characteristics can also be adjusted for certain electrochemical applications.High selectivity toward various targeted electroactive analytes, improved performance, cost-effectiveness, and scalability are just a few of the appealing characteristics of nano-based printed or modified electrodes.
These portable, nanoscale printed electrodes are also flexible, making them suitable for on-site tests. However, the kind of printed electrode materials and fabrication techniques used have an impact on their performance. In order to understand the various electrode materials, printing techniques, and applications for biosensors and the detection of organic and inorganic chemicals.
This review emphasises printed electrode materials that concentrate on characteristics including selectivity, sensitivity, and limit of detection. The future prospects, potentials, and difficulties of these cutting-edge printing electrode technologies are then discussed.
