Handling samples at micron scale is necessary for various tasks such as sample sorting, sample preparation, and micro-assembly. Unfortunately, the work with microscopic samples is often very challenging. In fact, it both requires the ability to delicately grab the small sample and to move with great precision to the desired location. A MEMS micro-gripper and piezo micromanipulators can be combined to provide that function. This micro-gripper is designed to handle objects between 5 and 50 µm and can be conveniently installed on Imina Technologies micromanipulator.
In this video, Barium Titanate (BaTiO3) microparticles with a diameter between 10 and 30 µm are picked and moved to destination with this micro-gripper. An additional miBot™ equipped with a probe is also used to unstick the microparticle from the gripper and to position it on the substrate. This combination of using a microgripper and a probe allows the operator to quickly transfer microspheres over long distances and precisely position them at destination with micrometer precision.
