This study aims to analyze the impact of different 3D printed biomimetic midsole structures on gait phase and gait ratio to optimize running shoe design. Participants wore shoes with various 3D printed midsoles while gait ratio(heel rotation, foot balance, forefoot balance, hallux stiffness, medial forefoot balance, and meta loading) and gait phase(forefoot off phase, foot flat phase, forefoot contact phase, and initial contact phase) data were collected using a gait analysis system. These metrics reflect foot pressure distribution, gait symmetry, and balance, providing insights into how midsole structures affect gait. The results showed that different 3D printed biomimetic midsoles significantly impacted gait phase and gait ratio. The 1TS structure, improved the stability of the stance phase and reduced swing phase imbalance, demonstrating its potential for optimizing gait balance and efficiency. This indicates that 3D printed biomimetic midsoles can notably influence running gait, with the 1TS structure enhancing stability and balance, offering a new direction for optimizing running shoe design to improve performance and comfort.

The repair of damaged peripheral nerves and the following restoration of functionality remain significant therapeutic challenges. Hollow nerve conduits currently available do not align with the ideal human model. Successfully mending nerve gaps requires incorporating biomimetic and functional features into neural conduit design.

Recent advances in four-dimensional (4D) cell scaffolds have shown promise for modeling morphogenic processes. While current 4D systems often rely on external stimuli, they tend to overlook the role of intrinsic cell-generated forces, such as cell contractile forces (CCFs), in driving tissue morphogenesis.

Extrusion-based 3D bioprinting is being increasingly adopted as a versatile biofabrication method for making biomimetic constructs in tissue engineering. However, the lack of ideal bioinks continues to limit its broader application. Conventional hydrogel-based bioinks typically possess a densely crosslinked nanoporous structure that hinders their ability to fully support cell behavior.

Strong attachment in complicated human body environments is of great importance for precision medicine especially with the rapid growth of minimal invasive surgery and flexible electronics. Natural organisms with highly evolved feet or claws can easily climb in complex environments from dry to wet and even underwater, providing significant inspiration for strong attachment research. This review summarizes the strong attachment behaviors of natural creatures in varied environments such as the gecko, tree frog, and octopus.
