Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators
Advanced Materials Technologies, EarlyView.Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.

Embedded cracks in brittle solids induced by laser-medium interaction (3D-ILC)
Yantu gongcheng xuebao, 2019 The research of fracture mechanics is based on physical experiments, which mainly deal with the specimen containing cracks and defaults. Since surface cracks and penetrated cracks are relatively easy to make and observe, the theoretical study on fracture

Advanced Materials Technologies, EarlyView.Multilayer aerosol jet printed components with a low‐loss, thermally stable dielectric are demonstrated using benzocyclobutene. Ink formulation and in‐line droplet evaporation control support high‐quality, versatile, and stable printing performance. A specialized measurement for low‐loss materials reveals promising microwave properties, which, combined
