The simulated Pong game environment, 1000 × 1000 pixels, separated into six regions
Gel plays Pong Left: The electric current sensor readings as they are received by the computer. The black, brown and red lines represent the top, middle and bottom sensors, respectively. Right: The simulated Pong game environment, separated into six regions. When the ball is in a region, it will darken and the corresponding electrode pair will stimulate the hydrogel. The score resets when the ball hits the left wall behind the paddle. (Courtesy: CC BY 4.0/Cell Rep. Phys. Sci. 10.1016/j.xcrp.2024.102151)
