Abstract: Electrochemical analysis is a cornerstone of biomedical engineering, yet traditional platforms are often too bulky and cost-prohibitive for the delicate electrodes used in modern medical devices. To bridge this gap, a modular, 3D-printed electrochemical cell was developed to characterize stretchable materials for bioelectronics, such as oxygen-generating electrodes critical for maintaining the viability of cell-based therapies.The system utilizes a precision-engineered, three-stage mechanism to achieve micro-scale alignment of electrical contacts, ensuring stable and repeatable measurements. By combining high-resolution stereolithography with an interchangeable glass chamber, the device provides a leak-proof environment with full optical access for real-time monitoring. Performance validation confirms that this platform maintains high sensitivity for advanced biosensor development while costing approximately $3,000 less than commercial alternatives. This versatile and accessible testing solution simplifies the fabrication of advanced biosensors, accelerating the translation of flexible electronics from the laboratory to clinical use.
