Multi‐material and dual‐stimulus coupled actuation micro‐gears for shape–rotation control in intelligent micro‐electro‐mechanical systems

FlexMat, EarlyView.
A multi‐material and dual‐stimulus coupled actuation micro‐gear (MDCAMG) is developed via femtosecond‐laser 3D printing combined with magnetic nanoparticle absorption, enabling integrated environmental sensing and remote actuation at the microscale. The device incorporates a pH‐responsive hydrogel matrix for autonomous swelling/shrinking and a magnetic
