Stretchable ionotronics have drawn increasing attention during the past decade, enabling myriad applications in engineering and biomedicine. However, existing ionotronic sensors suffer from limited sensing capabilities due to simple device structures poor stability leakage of ingredients. In this study, we rationally design fabricate a plethora architected leakage-free with multi-mode capabilities, using DLP-based 3D printing polyelectrolyte elastomer. We synthesize photo-polymerizable ionic monomer for elastomer, which is stretchable, transparent, ionically conductive, thermally stable, leakage-resistant. The printed possess robust interfaces extraordinary long-term stability. multi-material allows high flexibility structural design, tension, compression, shear, torsion, on-demand tailorable sensitivities through elaborate programming architectures. Furthermore, integrated that can perceive different mechanical stimuli simultaneously without mutual signal interferences. demonstrate kit consisting four shear one compressive sensor, connect it remote-control system programmed wirelessly control flight drone. Multi-material elastomers paves new avenues manufacturing stretchable by resolving deficiencies functionalities simultaneously.

Hydrogels, known for their mechanical and chemical similarity to biological tissues, are widely used in biotechnologies, whereas semiconductors provide advanced electronic optoelectronic functionalities such as signal amplification, sensing, photomodulation. Combining semiconducting properties with hydrogel designs can enhance biointeractive functions intimacy at biointerfaces, but this is challenging owing the low hydrophilicity of polymer semiconductors. We developed a solvent affinity–induced assembly method that incorporates water-insoluble into double-network hydrogels. These exhibited tissue-level moduli soft 81 kilopascals, stretchability 150% strain, charge-carrier mobility up 1.4 square centimeters per volt second. When they interfaced modulus enables alleviated immune reactions.
