Abstract:Gear transmission holds paramount significance for intricate mechanical systems. However, when the size of the driving gear is miniaturized to less than 50 microns, both manufacturing and control meet challenges. Here, a magnetic‐driven micro‐gear pair (MMGP) and its manipulation strategy are proposed. The MMGP is composed of two micro‐gears fabricated by the two‐photon polymerization (TPP) and its manipulation strategy depends on the gear engagement. The driving gear was processed with a magnetic photoresist … Show more
