The application belongs to the technical field of cell culture, and discloses a T cell activation and expansion method based on self-adaptive liquid-liquid interface and application thereof. The application provides application of a liquid-liquid interface culture system in T cell activation and expansion, wherein the liquid-liquid interface comprises a two-dimensional liquid-liquid interface and a liquid-liquid interface microsphere, both of which can form a protein nanofilm at an oil-water interface, and the protein nanofilm is used to load molecules providing T cell receptor activation signals and / or molecules providing T cell costimulatory signals, so as to construct a self-adaptive T cell activation interface with dynamic molecular display capability. Compared with a traditional rigid solid culture dish and a magnetic bead system, the liquid-liquid interface has fluidity, molecular migration and interface responsiveness, and is more conducive to T cell receptor aggregation, formation of an immunological synapse-like structure and synergistic integration of T cell receptor activation signals and costimulatory signals.

The utility model discloses a kind of foot plate structure, artificial leg and robot, foot plate structure includes: back plate;Front plate, with the front end rotation connection of the back plate;Elastic member, two ends are connected respectively the back plate and the front plate;First gap is formed on the back plate, and the elastic member is located in the first gap.In initial state, front plate is arranged along the extension direction of back plate, and front plate and back plate present unfolded state.In walking or running process, front plate touches ground, then front plate and back plate rotate each other, and front plate and back plate present bending state.When foot plate structure leaves ground, or foot plate structure is flatly pasted ground, front plate and back plate present unfolded state under the action of elastic member.Therefore, the bionic effect of foot plate structure is better.

This invention discloses a biomimetic dragonfly flapping-wing aircraft with adjustable sweep amplitude driven by an air source, belonging to the field of aircraft technology. It includes: a base plate support, a transmission mechanism, a sweeping flapping mechanism, a pair of front flapping wings, and a pair of rear flapping wings. The transmission mechanism includes a front air source driven transmission mechanism and a rear air source driven transmission mechanism with identical structures located on the front and rear sides of the base plate support, enabling differential sweeping movements of the two pairs of flapping wings. Each flapping wing root is equipped with an adjustable sweeping flapping mechanism and a micro-gear. The front air source driven transmission mechanism drives the sweeping support to rotate circumferentially via an air source rotating blade engine, which in turn drives the flapping wings to sweep through a sweeping swing frame. The amplitude and speed of each flapping wing's sweeping movement can be controlled independently. During flight, the sweep amplitude or speed of the front and rear flapping wings on the same side can be controlled to be greater than that of the front and rear flapping wings on the other side to achieve turning movements and tailless flight control.
