Summary: This study introduces a convenient method for transferring perovskite patterns to different surfaces using a removable polymer, enabling integration of perovskite devices. The transfer method allows fabrication of a perovskite image sensor array on soft contact lenses and heterogeneous integration of a perovskite photodetector array with pressure-sensitive silicon transistors, creating a multiplexed sensing platform.

Summary: Color vision deficiency (CVD) affects normal functioning, but tinted glasses/contact lenses can help alleviate this. However, current lenses are tinted throughout, causing discomfort and drawing attention. Researchers have developed CVD lenses by tinting only the midportion of a lens, providing a solution without unnecessary attention.

Summary: The rapid development of regenerative medicine has provided new opportunities for disease treatment, but faces technical and translational barriers in clinically adopted approaches. The selection and screening efficiency of key material factors are relatively low, and the design and screening of biomaterials genomics are crucial for achieving osteoinduction and osteoconduction. The bone regeneration test chip fabricated by digital light projection enables high-throughput screening of specific biological functions in regenerative medicine.

Summary: Central airway obstruction is a life-threatening disorder with high physical and psychological burden to patients. Standard-of-care silicone airway stents provide immediate relief but are prone to migration, requiring additional surgeries for removal. Customized bioresorbable airway stents produced by 3D printing offer a promising solution with tunable elastomeric properties and suitable biodegradability.

Summary: The value of face contact pressure significantly affects the wear life and leakage rate of mechanical seals. This study discusses the critical porosity for zero-leakage at the wetting and non-wetting sealing interfaces and investigates the influence of end-face frictional heat on friction and wear. It establishes the design criteria for face contact pressure in mechanical seals for zero-leakage and long-life operation. The study also calculates the face contact pressure range for mechanical seals working in different liquid media and analyzes the influence of various working conditions.

Summary: Thermal insulation aerogels made from lignocellulose nanofibrils (LCNFs) show great potential for temperature-sensitive electronic components. In this study, we successfully prepared LCNFs aerogels with customizable size and high precision and used 3D printing to create customized thermal insulation materials. These aerogels have low density, high thermal stability, superior UV resistance, and low thermal conductivity.

Summary: The revolution of 4D printing combines smart materials with additive processes to create objects that respond to external stimuli. This study used a modified 3D printer to create gear-based devices that can be remotely controlled. The printing process involves magnetoresponsive polymers with self-assembled microstructures, which can generate rotation or bending motions. The research also demonstrated the use of magnetoresponsive gears to transfer torque and create complex assemblies that can be remotely controlled.

Summary: In this paper, a vibration model of the reciprocating seal is established for the first time, and the effects of vibration on sealing performance are revealed. The study shows that vibration affects sealing performance, with maximum leakage rate at the resonance point and decreasing as the vibration frequency moves away from the resonance frequency. Increasing the vibration amplitude increases the net leakage rate.

Summary: Starch-based tablets with tailored releases were prepared using 3D printing, and the importance of excipient origin as well as the effect of tablet geometry on drug release were analyzed. Different origins of starch influenced the rheological properties of inks, resulting in tablets with different microporous structures and compression and swelling behaviors. Tablets combining different starches and geometries were able to tailor the drug release and demonstrate applicability in personalized therapies.
