Emergence of odd elasticity in a microswimmer using deep reinforcement learning [PDF]
Physical Review Research, 2023 We use the Deep Q-Network with reinforcement learning to investigate the emergence of odd elasticity in an elastic microswimmer model. For an elastic microswimmer, it is challenging to obtain the optimized dynamics due to the intricate elastohydrodynamic

Bioinspired enzyme-powered microswimmer for pH-sensitive locomotion in the gastric mucus
AIP Advances, 2023 Helicobacter pylori penetrates the gastric mucus by producing ammonia with urease, which locally raises the pH and turns the nearby gel into a solution. Here, we mimic this strategy by proposing an enzyme-powered microswimmer in the gastric mucus in one-
