The environmental impact of manufacturing an electrochemical measurement system is evaluated using Life Cycle Assessment (LCA). This study focuses on identifying the most impactful materials and processes with the aim of eco-design on manufacturing an ultramicroelectrode array sensor: reducing environmental impacts through process modification, material changes and reducing electricity consumption. A cradle-to-gate approach is used. The results highlight that metal (i.e., gold and titanium) and insulator deposition are the most impactful steps, primarily due to high electricity consumption.
