AI Technical Summary
Existing magnetically controlled capsule robots rely on a continuous external magnetic field to maintain their working state, resulting in high energy consumption and insufficient ability to maintain functional state, making it difficult to work continuously in complex internal environments.
The valve control component, made of soft composite material, includes a magnetic soft valve vane and a magnetic soft valve frame. This ensures that the coercivity of the valve vane is higher than that of the valve frame. By applying a preset external magnetic field, the valve frame undergoes controllable magnetization and reconstruction, thereby switching the magnetic interaction between the valve vane and the valve frame from an attraction force to a repulsion force, thus maintaining a self-sustaining release state.
It reduces system energy consumption, enhances the ability to maintain functional status, and can maintain the on state by relying on residual magnetic repulsion after the external magnetic field is removed, thereby improving the working stability and endurance of the equipment in the absence of external power.
