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.

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...
