Development of Precision Tweezers Based on Displacement Reduction Mechanism Using Magnetic Force

Abstract

Microscopic work done under a microscope can be a very inefficient process. There are many delicate tasks where unskilled operators often make mistakes. For this reason, time is wasted in learning how to use microtools that are suited to the size and characteristics of microscopic objects. In this study, a powerless displacement reduction mechanism using magnetic force have been developed. The developed mechanism can reduce fingertip displacement from a few centimeters to several tens of micrometers with a single mechanism, and the full stroke and displacement reduction rate can be adjusted by the gap between the magnetic poles. The usefulness of precision tweezers constructed with this device for microscopic work has been investigated. -
