The geometrical constraints and dimensional tolerances lead to specific design issues of MEMS manipulators for biological applications. target properties become even more important in the case vitro manipulation cells. Several solutions have been proposed literature, however, some related thermal heating microgripper tips electric voltage effects still remain unsolved. This paper reports additi...
In this paper, modeling and control strategies for a new observability-optimized piezoelectric microactuator are presented. The targeted applications concern mainly the design of microgripper for micromanipulation tasks. The device has been designed using a topological optimization method, which takes into account the optimal full integration of piezoelectric actuating and sensing elements with...
We present a novel method for the three-dimensional (3D) control of microrobots within a microfluidic chip. The microrobot body contains a hollow space, producing buoyancy that allows it to float in a microfluidic environment. The robot moves in the z direction by balancing magnetic and buoyancy forces. In coordination with the motion of stages in the xy plane, we achieved 3D microrobot control...
A tele-haptic system for microassembly applications is currently being developed at the Delft University of Technology, with the goal of achieving superior performance by providing enhanced feedback to the human operator. Assembly of a micro-harmonic drive is used as a benchmark to fully evaluate the proposed telehaptic system by investigating the control strategies and the individual subsystem...
The adhesion between a micro-object and a microgripper end-effector is an important problem in micromanipulation. Canceling or reducing this force is a great challenge. This force is directly linked to the surface chemical structure of the object and the gripper. We propose to reduce the adhesion force by using a self-assembled monolayer structuring on one surface. The surface was structured by...
