Figure 5
The controllable temperature range of the robotic cover surface. The Peltier devices are controlled to maximum and minimum temperatures in our experimental setup (87 °C and 12 °C, see Supplementary Note S2). The temperature responses of the water (lower, middle, upper side of the tank) and that of the cover are monitored. The robotic cover surface is successfully cooled and heated from 15.8 to 66.6 °C. This range covers the temperature that are comfortable for humans18,19,64.
