3D Shape Control of Printed Micro‐Electrodes with Substrate Reshaping (Adv. Mater. Technol. 7/2025)

3D Shape Control In article number 2401641, Marcos Fernández-Prada, Martí Duocastella, and co-workers present a novel additive manufacturing method for micro-electrodes that overcomes wetting limitations in traditional printing techniques. By printing on pre-stretched elastomeric substrates, electrodes shrink upon release, achieving up to an 8-fold increase in aspect ratio in a single printing pass. This approach advances electronic device miniaturization while enhancing sensitivity and reducing overall footprint.
