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

In this paper precise specifications are given for a microgripper based on a polyarticulated micromechanism. This polysilicon gripper actuated by Scratch Drive Actuators (SDA) has dimensions of 1.2mm × 1.6mm and a thickness of 4.5µm . The stroke of its jaws is about 275µm each, with a stroke ratio of 5.

Design Tradeoffs for Electrothermal Microgrippers
Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007Microgrippers based on electrothermal actuation were designed and fabricated using the deep reactive ion etching (DRIE) process with 100mum thick silicon on insulator (SOI) wafer. The design requirements are restricted to basic manipulation tasks such as pick and place, and nonprehensile manipulation.

Electrostatically driven microgripper
Microelectronic Engineering, 2002Abstract In this work we report on microactuators and microgrippers fabricated from SOI (silicon-on-insulator) wafers by a surface and bulk micromachining fabrication technology. The main advantages of this technology are: (a) large thickness of the devices (10–40 μm) resulting in devices which are stable against disturbing forces perpendicular (z ...

Integrated fabrication of a microgripper
Journal of Shanghai University (English Edition), 1999Successful implementation of simple mechanism on silicon chip is a prerequisite for monolithic microrobotic systems. This paper describes the integrated fabrication of polycrystalline silicon microgripper. Link, fixed and active joint, and sliding flange structures with dimensions of micrometers have been fabricated on the substrate of monocrystalline ...

An automatic vacuum microgripper
2010 8th World Congress on Intelligent Control and Automation, 2010Picking and releasing the micro parts is one of the most important tasks for the microassembly robot. Downsizing the grippers used in the macro world is not suitable to fulfill the manipulation in the micro world because of the different scaling of gravity and adhesion.

An electrowetting based microgripper
2008 51st Midwest Symposium on Circuits and Systems, 2008In this paper, we present a novel capillary microgripper that can pick up and release micro objects simply by electrowetting. Electrowetting on dielectric (EWOD), a phenomenon which uses electrical potential to manipulate the surface tension of a liquid droplet is utilized to control the lifting forces.

Tactile microgripper for automated handling of microparts
Sensors and Actuators A: Physical, 1996Abstract As a part of a microrobot we present a micromachined gripper system which has both sensor and actuator integrated. The actuation principle is based on the bimetallic effect. Measurements show that the actuator has a linear range up to 140 μm tip deflection, which corresponds to an operating power of 80 mW.

A microgripper using smart piezoelectric actuators
Proceedings. 2000 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2000) (Cat. No.00CH37113), 2002The manipulation of very small objects is one of the most important tasks in microrobotics. Micromanipulators are required in all fields where precise manipulation of very small objects must be performed like microsurgery or assembly of MEMS. It is well known that downsizing the tools used in the macroworld is not appropriate to achieve tasks in the ...
