“…From the perspective of meeting the needs of users, design can be divided into two types: modeling design is to meet the emotional needs of users, functional design is to meet the functional needs of users, modeling design and functional design are combined, and the product has both "use" and "sense" is the goal pursued by designers. The design of the vehicle cab is a typical example of the integration of shape design and function design, the sense of security in shape design, and safety in function design [8][9][10].…”

“…Through the relay‐driven mechanism of biomimetic structures, continuous monitoring of sweat is achieved. [ 33 ] To achieve optimal self‐propulsion, we conducted in‐depth analysis and optimization of the key structures. For the spine structure, theoretical analysis and simulation experiments revealed that the droplet propulsion velocity on the spine surface is influenced by the cone angle, with the fastest droplet motion observed at an angle of 8°.…”

Wearable sweat sensors exhibit significant promise in the realm of smart healthcare. Efficient and non‐contaminating continuous sweat collection, transport, and disposal are crucial for enhancing detection accuracy. In this study, a novel wearable sweat sensor is presented that integrates various biomimetic structures, including cactus‐inspired spine, shorebird‐inspired conical through‐holes, and frog‐foot‐inspired micro‐grooves. These structures facilitate sweat droplets to be automatically transported from the skin to the sensing chamber and discharged without external power. First, theoretical analysis, simulation, and experiments based on self‐driven droplet mechanisms to determine the optimal transport efficiency parameters for biomimetic structures are conducted. Next, a novel sweat transport module is fabricated through ultra‐precision 3D printing according to these optimal parameters. And this module has excellent sweat collection performance contrastively. Finally, the novel biomimetic sweat transport module is integrated with a high‐sensitivity glucose detection electrode, resulting in a wearable sweat glucose detection system. Human experiments monitoring glucose metabolism in sweat verify the correlation between glucose concentrations in blood and sweat, which proves the feasibility of reflecting changes in the body's circulatory system by monitoring changes in sweat composition.

Inspired by the convex hull structure of the dung beetle head’s surface, we extracted the non-smooth surface morphology of its head and designed a rubber bushing with a representative structure according to the bionics principle. According to the fitting results of the test data, Ogden N3-Prony N3 was selected as the hyper-viscoelastic constitutive model of the rubber material. Then, the two-direction (radial, axial) motion characteristics of the flexible friction pair in the rubber bushing were systematically analyzed from the aspects of stress, strain and thermal effect through the combination of numerical simulation and experimental research. Finally, the bionic design with the best drag reduction and wear resistance was determined.
