, 2021 En l'actualitat, el mercat de l'IoT està fragmentat en multitud de proveïdors que, generalment, imposen als usuaris l'ús de les seves solucions privatives per tal d'interactuar amb els seus dispositius. Per altra banda, els usuaris també poden desenvolupar el seu propi sistema per tal de tenir un control total.

Advanced Science, EarlyView.Day‐night cycles trigger sharp relative humidity (RH) shifts in greenhouses. Rapid humidity drops dehydrate Corynespora cassiicola spores, inducing shrinkage, jerking movements, and weakened inter‐spore connections that drive detachment. Wind is essential for dispersal, with even mild airflow enabling rapid pathogen spread. These synergistic effects of

CMOS‐Compatible HfOx‐Based Radiation Hardening Component for Neuromorphic Computing Applications
Advanced Electronic Materials, EarlyView.HfOx‐based resistive random‐access‐memory (TiN/Ti/HfOx/RuOx/TiN) is fabricated by CMOS‐compatible materials – ruthenium, with a maskless etching‐free process. After a 5‐Mrad total ionizing dose test, the results showed non‐degradation performance, memory window ≈ 40 with operation power < 2 mW, > 8k endurance cycles, and 15‐year retention, which can be
