Untethered Microgrippers for Precision Medicine
Small, 2023AbstractMicrogrippers, a branch of micro/nanorobots, refer to motile miniaturized machines that are of a size in the range of several to hundreds of micrometers. Compared with tethered grippers or other microscopic diagnostic and surgical equipment, untethered microgrippers play an indispensable role in biomedical applications because of their ...

Development of microgripper system
2011 XXIII International Symposium on Information, Communication and Automation Technologies, 2011The paper presents the experimental development of micro/nano robotic cell for assembling the micro objects. Three techniques for gripping of micro objects with micro/nano robot are presented. The first one uses a two finger gripper and is suitable for objects which are greater than 100 μm.

Sensors and Actuators A: Physical, 2001
A microgripper system is presented, which consists of a monolithic shape memory alloy (SMA) device of 2 × 5.8 × 0.23 mm3 size and an integrated optical position sensor. By use of an integrated gear actuator, the motion of gripping jaws is transmitted into a linear motion of an integrated optical slit, which is detected by change of optical transmission.

Optimal Design of Microgripper
First International Conference on Innovative Computing, Information and Control - Volume I (ICICIC'06), 2006This paper presents a microgripper design and utilizes the topology optimum method to obtain larger output force and displacement. The goal of this study is to obtain the sharpest topology layout by simulation and computing. The difference between compliant mechanisms and traditional mechanisms is that compliant mechanisms have flexible pieces to ...

Performance Evaluation Methods for Microgrippers
Volume 4: 19th Design for Manufacturing and the Life Cycle Conference; 8th International Conference on Micro- and Nanosystems, 2014In precise manipulation and assembly of components with sub-millimetric dimensions, the role of the gripping tools is fundamental. In the literature, many different types of the so-called microgrippers have been presented, based on different working principles, to cope with the issues related to the gripping, the handling and the release of different ...

4-axis electromagnetic microgripper
Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003This paper describes a novel 4-axis microgripping system consisting of two fingers, each driven by a 2-axis moving coil actuator taken from a CD-lens assembly. These electromagnetic actuators are small, very linear, virtually frictionless and low cost. We measured the electrical actuator parameters and characterized the actuator performance in terms of

Compliant Microgripper for In-Vitro Biological Manipulation
2022We present a feasibility study on biological tissue and cell manipulation by a novel, multi-hinge microgripper characterized by high dexterity and complex in-plane tips displacement, while being at the same time highly compact and easy to manufacture via MEMS technology. The device was obtained by combining selective flexibility with planar fabrication
