Robotic Plasma System for Rapid Activation of Mass-Produced Electrochemical Sensors.

ABSTRACT: Polishing, cleaning, and activation of solid electrode surfaces are common in electrochemistry; however, they are often labor-intensive, operator-dependent, and poorly reproducible. In the context of large-scale production of disposable solid-state sensors, such as screen-printed electrodes (SPEs), traditional surface conditioning procedures have proven to be impractical and incompatible with automated workflows. Here, we report the development of a low-cost robotic system that integrates a Tesla coil-based air-plasma generator with a Python-controlled XY motion platform for rapid (∼15 s per 0.11 cm²) and reproducible surface activation of SPEs. The main novelty of this study lies in the mechanization and reproducibility of the plasma activation process, achieved through
