In vertical positioning systems, the friction force and the gravity load cause significant error.In order to minimize the effect of friction and gravity load, this paper presents the noncontact gravity compensator applying magnetic fluid freeze dried seals.The structure of the magnetic fluid seals was proposed for the linear motion system, and the
Human trabecular meshwork is a sieve-like tissue with large pores, which plays a vital role in aqueous humor outflow.Dysfunction of this tissue can occur, which leads to SUN HATS glaucoma and permanent vision loss.Replacement of trabecular meshwork with a tissue-engineered device is the ultimate objective.This study aimed to create a biomimetic str
