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.

Tunable Applicator for Microneedle‐Based Medical Devices
Advanced Materials Technologies, EarlyView.This paper presents a simple, low‐cost tunable applicator (TAPP) for microneedle array patches that uses a material‐agnostic controlled‐fracture mechanism to ensure reliable skin penetration and uniform array engagement. The scalable, modular design is compatible with injection molding and 3D printing, can be integrated directly into patches, and is ...
