Based on the magnetic grid torque transducer and a new computer aided method to measure phase difference, a new measuring system for dynamic torque is developed.

采用磁栅转矩传感器和一种新的微机辅助相位差检测方法，研制了一套新型动态转矩测量系统。

One way this might be done is to place a grid of wires behind them and induce a magnetic field where the wires cross. The spheres at the intersections would then rotate.

方法之一，有可能是在其背后建立一网格线和在线经过的地方引入磁场，在这地方的微珠就可以旋转了。

One challenge would involve creating a magnetic head that could hover over those dots, read their signal and write new data onto the grid.
