3D-Printed Micro-Manipulator with Compliant Mechanism for Biological Application

We developed a topology-optimized micro-manipulator with a compliant mechanism, by using a laboratory-constructed high-resolution micro-stereolithography system with a blue laser to manipulate and stimulate organoids. The fabricated micro-manipulator could be driven linearly concerning the input load that was controlled by a force control system using a linear motor. Finally, the micro-manipulator succeeded in grasping, moving, and releasing the organoids.
