Optimizing The Design of 3D Printed Sensors Through Electrochemical Analysis

Non-invasive electrochemical sensors are pivotal in healthcare, particularly in diabetes management through glucose sensors. Enhancing these benefits, fused deposition modeling (FDM) 3D printed molds play a crucial role in ensuring the reproducibility of sensor fabrication. Leveraging cellulose paper as a substrate further augments biocompatibility, biodegradability, and flexibility, aligning with environmental sustainability. The study encompassed the design and 3D printing of nine sensor molds, facilitating electrochemical activity assessment via cyclic voltammetry. This comparative analysis aimed to pinpoint an optimal sensor design, emphasizing efficacy while minimizing spatial requirements. The ideal configuration encompasses circular, elongated counter electrodes, and concentrated, round-shaped working electrodes, ensuring precision in diabetes management. This innovative approach showcases the potential of technology and material choices in advancing non-invasive healthcare solutions.
