The team likened this to early movies that caused motion blur due to insufficient frame rates, or early monitors that displayed blurry images due to too few pixels. Currently, tactile devices face similar bottlenecks of spatio-temporal resolution, and voxelite achieves spatial and temporal resolusyon which corresponds to the human tactile system for the first time, which is an important breakthrough in the tactile field. The main technology of the device is to embed densely arranged micro-controllable nodes. Each node consists of a rubber dome, a conductive layer and a built-in electrode. It uses the principle of electrostatic adsorption to precisely adjust the pre确保皮肤 - 高压模拟粗糙的表面，低压呈现光滑的触感。在最宽的版本中，节点间隔仅约 1 毫米，有效覆盖了人类触摸感受器的范围。 Voxelite有两种工作模式：在主动模式下，节点每秒可伸缩800次，在光滑的屏幕上生成虚拟纹理；在主动模式下，节点每秒可伸缩800次，在光滑的屏幕上生成虚拟纹理；在被动模式下，超薄的材质几乎影响了真实的触感。测试数据显示，佩戴者识别虚拟方向图案的准确度为87%，识别皮革、灯芯绒、毛圈布等真实纺织材料的准确度为81%。展望未来，该团队预计该技术将深度集成到智能设备中。就像解放耳朵的蓝牙耳机一样，voxelite 可以将光滑的屏幕变成三维触摸界面。网上购物者可以触摸织物的纹理，视障人士可以阅读触觉地图，游戏玩家可以感受橡皮筋的张力和石墙的粗糙度。
