Extended Data Fig. 6: Phototactic performance and the speed-temperature correlation of the PTV.
From: Self-regulated underwater phototaxis of a photoresponsive hydrogel-based phototactic vehicle
a, Snapshots of the time evolution of the PTV phototaxis under horizontal illumination with a photonic power density lower than 1 Sun (1 mW·mm-2). b, Time-dependent displacement of the PTV in the x and z directions. c, d, Time evolution of the local temperature on the illuminated surface and speed of the PTV as directly measured (c) and simulated (d) through the FEM-based CFD tool. The experiment and the simulation exhibit a correlation between speed and temperature and are in good agreement with each other.
