The Future at Your Fingertips: How Electroanalysis is Revolutionizing Our World
From wearable health monitors to environmental sensors, discover how electroanalysis is transforming technology and improving lives
Introduction: The Invisible Science Touching Your Life
Imagine a wearable device that can detect disease from your sweat, a sensor that can monitor ocean pollution in real time, or a battery that stores clean energy more efficiently. What connects these diverse technologies? The answer lies in electroanalysis, a sophisticated field of analytical chemistry that measures electrical signals to obtain chemical information. In June 2026, Lisbon, Portugal will host the 20th International Conference on Electroanalysis (ESEAC 2026), where scientists from around the globe will gather to share breakthroughs that are quietly reshaping our world 1 .
Electroanalysis has undergone an impressive evolution in recent decades, growing from a specialized laboratory technique to a key research field that bridges life sciences, materials science, and environmental monitoring 3 . This conference continues a tradition begun in 1986 by Professor Malcolm R. Smyth, serving as a crucial biennial meeting point for the international scientific community to exchange knowledge and forge collaborations 1 .
From its historic beginnings to today's cutting-edge applications, electroanalysis has become indispensable in our quest for better healthcare, cleaner environment, and more sustainable energy solutions.

The 3D-Printed Revolution: A Deep Dive into Accessible Science
Among the most exciting trends in electroanalysis is the integration of additive manufacturing, or 3D printing, which is dramatically lowering barriers to creating sophisticated laboratory equipment. This was highlighted recently at the Electro-Summer 2025 school, a Polish-Brazilian hybrid event focused on how additive manufacturing empowers electrochemical innovation 6 .
The Experimental Goal
Researchers aimed to develop low-cost, customizable electrochemical sensors using readily available 3D printing technology. The primary challenge was to create electrodes that could rival the performance of commercial alternatives at a fraction of the cost, making electrochemical analysis accessible to laboratories with limited infrastructure 6 .
Methodology: Step-by-Step Sensor Creation
The experiment followed a systematic approach to transform digital designs into functional analytical tools:
Step 1: Design and Printing
Researchers began by creating digital models of electrodes using CAD software. These designs were then printed using fused deposition modeling (FDM) technology with graphene-infused PLA filaments 6 .
Step 2: Surface Activation
The 3D-printed electrodes underwent crucial electrochemical activation to enhance their performance. This process increased the active area, thereby improving sensitivity 6 .
Step 3: Testing and Validation
The activated electrodes were tested using standard electrochemical techniques like cyclic voltammetry and amperometry to quantify their performance in detecting specific analytes 6 .
The experiments demonstrated that 3D-printed electrodes could achieve performance comparable to commercial electrodes at significantly reduced cost. As noted by Prof. Rodrigo A. A. Muñoz, a leader in this field, "Additive manufactured electrodes represent a new generation of low-cost electroanalytical platforms" that can revolutionize how laboratories worldwide conduct chemical analysis 6 .
