Ultra‐Thin Soft Pneumatic Actuation for Minimally Invasive Neural Interfacing

Advanced Materials Technologies, EarlyView.
Parylene C is a common polymer in bioelectronics, favored for its biological and chemical inertness. However, this makes bonding layers of Parylene C together very challenging. Here it is a laser to selectively weld layers of Parylene C to create high‐pressure fluidic actuation devices.
