Active Texture Presentation Apparatus Driven by High-Density Flexible Electromagnetic Coil Array

摘要

Disclosed is a texture presentation apparatus driven by a high-density flexible electromagnetic coil array, including a surface layer and a driving layer. The surface layer is in direct contact with the fingertip of a finger to ensure interaction safety of a user, is capable of adjusting the friction force when the finger touches and slides on the surface layer, and has a shielding and protection effect on the driving layer; the driving layer includes a stretchable soft substrate and a plurality of micro driving units, each micro driving unit is independently controllable, the driving layer adjusts the microscopic geometric morphology of a texture surface; the texture presentation apparatus is capable of implementing multi-scale fine texture presentation; when the fingertip comes into contact with the surface layer, the texture presentation apparatus controls, based on different surface textures of an object to be simulated in a virtual environment.
