Dear Colleagues,

Advances in three-dimensional (3D) printing are enabling the design and fabrication of smart materials with direct applications in tissue engineering and biosensing. The integration of biosensors with 3D-printed constructs offers unique opportunities for real-time monitoring of cellular environments, precise assessment of biochemical signals, and the development of patient-specific therapeutic systems. These approaches are accelerating progress in engineered tissues, organ-on-chip models, implantable sensors, and wearable diagnostic devices.

This Special Issue focuses on the convergence of 3D printing and biosensor technologies, emphasizing materials innovation, biofabrication strategies, functional integration, and translational potential. We welcome original research, reviews, and communications covering novel smart biomaterials, sensor-embedded scaffolds, advanced additive manufacturing techniques, and clinically relevant applications. By highlighting interdisciplinary efforts, this Special Issue aims to advance scalable and impactful solutions at the interface of bioprinting, tissue engineering, and biomedical sensing.
