Design of a Compliant Mechanism Based Four-Stage Amplification Piezoelectric-Driven Asymmetric Microgripper

open access: yesMicromachines, 2019
The existing symmetrical microgrippers have larger output displacements compared with the asymmetrical counterparts. However, the two jaws of a symmetrical microgripper are less unlikely to offer the same forces on the two sides of a grasped micro-object

Design of large-displacement asymmetric piezoelectric microgripper based on flexible mechanisms

open access: yesNanotechnology and Precision Engineering, 2019
The output displacement of the traditional symmetrical microgripper is large, but its micro-components or parts are easily damaged due to the uneven force exerted on the left and right jaws of the gripper.

Design of a Novel MEMS Microgripper with Rotatory Electrostatic Comb-Drive Actuators for Biomedical Applications

open access: yesSensors, 2018
Primary tumors of patients can release circulating tumor cells (CTCs) to flow inside of their blood. The CTCs have different mechanical properties in comparison with red and white blood cells, and their detection may be employed to study the efficiency ...

Heat Transfer Scale Effect Analysis and Parameter Measurement of an Electrothermal Microgripper

open access: yesMicromachines, 2021
An electrothermal microgripper is an important actuator in microelectromechanical and micro-operating systems, and its temperature field analysis is the core problem in research and design. Because of the small size of an electrothermal microgripper, its

Universal Soft Robotic Microgripper [PDF]

open access: yesSmall, 2018
AbstractHere, a soft robotic microgripper is presented that consists of a smart actuated microgel connected to a spatially photopatterned multifunctional base. When pressed onto a target object, the microgel component conforms to its shape, thus providing a simple and adaptive solution for versatile micromanipulation. Without the need for active visual

A Microgripper with a Post-Assembly Self-Locking Mechanism

open access: yesSensors, 2015
In this work, we report a new design for an electrostatically actuated microgripper with a post-assembly self-locking mechanism. The microgripper arms are driven by rotary comb actuators, enabling the microgripper to grip objects of any size from 0 to ...

A Submerged Freeze Microgripper for Micromanipulations [PDF]

open access: yesProceedings 2007 IEEE International Conference on Robotics and Automation, 2007
Efficient, reliable and flexible handling is still very challenging in micromanipulation and micro-assembly. In this paper, we propose an original thermally actuated gripper based on the use of ice to manipulate submerged artificial micro-objects sized under 100 mum.
