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

Evaluation of 6‐Month Knowledge Retention and Satisfaction After Pedagogical Escape Games in Dentistry

Journal of Dental Education, EarlyView.
ABSTRACT Purpose To evaluate 6‐month knowledge retention and long‐term satisfaction after two pedagogical escape games (PEGs) addressing foundational (3D printing) and clinical (pediatric dentistry) content in a dental curriculum. Methods In this monocentric serial cross‐sectional study, immediate post‑PEG knowledge was assessed in fifth‑year dental ...
