Fig. 1: Schematic representation of the dynamic Brownian reservoir computer.
From: Gesture recognition with Brownian reservoir computing using geometrically confined skyrmion dynamics
The triangular stack (light gray; composition shown in the top right) is connected with chromium/gold contacts at the corners (half transparent yellow). In the used setup, only the lower corners A and B are connected to the time-dependent voltage. Here, four examples are shown in different colors, from each gesture type one input signal. The third corner C is not connected and therefore floating. The skyrmion is presented as a dark gray spot as visualized by magneto-optical Kerr microscopy. Possible skyrmion response trajectories to the time dependent voltages are shown by colored arrows.
