Abstract In this work, a new method of multi‐material printing in one‐go using commercially available 3D printer is presented. The approach simple and versatile, allowing the manufacturing layered or same layer. To best knowledge, it first time that printed Poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) micro‐patterns combining different materials are reported, overcoming mechanical stability issues. Moreover, conducting ink engineered to obtain stable in‐time while retaining sub‐100 µm resolution. Micro‐structured bio‐shaped protuberances designed as electrodes for electrophysiology. these microstructures combined with polymerizable deep eutectic solvents (polyDES) functional additives, gaining adhesion ionic conductivity. As result novel electrodes, low skin impedance values showed suitable performance electromyography recording on forearm. Finally, concluded use polyDES conferred over time, usability electrode 90 days after fabrication without losing its performance. All all, demonstrated very easy‐to‐make procedure allows PEDOT:PSS soft, hard, and/or flexible substrates, opening up paradigm multi‐functional field bioelectronics wearables.

Multifunctional components are pivotal for the physical intelligence of synthetic robots, mirroring multifaceted roles seen in natural organisms. Achieving such complexity is challenged by rigidity and intricate assembly required monofunctional parts difficulty designing materials that respond distinctly to multiple stimuli. A key challenge developing multifunctional devices co-evolve intrinsically multistimuli-responsive with their fabrication methods. In this context, mixed ionic-electronic conductivity (MIEC) stand out, as dual enables concurrent processing diverse signals. However, lack precise techniques has restricted full exploitation MIECs creating multimaterial, complex-shaped, hierarchically structured devices. We introduce high-conductivity soft ionogel/single-walled carbon nanotube (SWCNT) MIEC composites (ISMCs), 3D-printed high resolution using vat photopolymerization (VPP). These showcased pressure–temperature sensors capable detecting pressure thanks a SWCNT network sensing temperature broad range sensitivity owing ionic an liquid (IL). suggest electronic (1.82 mS/cm) (1.02 conductivities, combined precise, single-step VPP 3D-printing, lay groundwork versatile, wide applications.
