Biohybrid Micro Pinwheel Powered by Trapped Microalgae

This paper proposes a biohybrid pinwheel rotated by the propulsion force of microalgae, Chlamydomonas reinhardtii. To make the microalgae rotate the pinwheel larger than themselves, we designed the pinwheel to have traps holding microalgae without preventing their motions. As a result, the biohybrid pinwheel succeeded in the rotation at the average angular velocity of 0.78 rad/s.
