Abstract :
We succeeded higher adhesion force between cells and base materials. Hybrid actuators were composed of both artificial material and biological driving source. In this report, we focused on surface roughness of the materials and revised energy transmission on the hybrid actuators to increase generative force. We revealed that controlled rough surface made higher efficiency than flat surface. A 3.2mm/min swimming robot was succeeded by this method and cell viability was maintained.
