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 ...

Experimental Evidence of Free Carrier Generation in 2D Hybrid Organic–Inorganic Perovskites
Advanced Optical Materials, EarlyView.ABSTRACT Despite the significant potential of 2D hybrid organic–inorganic perovskites (2DHOIPs) for high‐efficiency optoelectronics application‐comparable to their 3D counterparts, the fundamental carrier photogeneration remains unclear. In contrast to conventional ultrafast optical property characterization, we use ultrafast photocurrent spectroscopy ...
