Abstract

The video presents high power, high precision and high speed drive of on-chip robot and its biomedical applications. The magnetically driven microtool (MMT) actuated by permanent magnets was employed as a microrobot due to its strong output force in the order of dozens of millinewtons and the ultrasonic vibration was applied to the microfluidic chip in order to reduce the friction on the MMT. We have achieved 1.1 micrometer positioning accuracy of the MMT, which is 100 times higher than in the case of previous method. In addition, owing to the fast response speed of the MMT to the drive stage, the MMT can move with high speed of up to 5 Hz ,which is upper limit of the stage, in 3-degree of freedom. We have applied this drive method to the enucleation of oocyte process. The dual-arm MMT were precisely removed the nucleus part in a few seconds.
