Advanced Healthcare Materials, EarlyView.A portable respiratory monitoring device based on a flexible PZT sensor captures pressure‐ and temperature‐related airflow responses in a single waveform. Polarity‐opposed piezoelectric and pyroelectric components generate a narrow transient spike and a broad quasi‐steady peak during both inhalation and exhalation. This dual‐component structure enables

Advanced Materials, EarlyView.We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

Managing Nasal Airway Obstruction: The Otolaryngology Approach
, 2020 Nasal airway obstruction is a common problem presenting to primary care providers in clinical practice. It is easy to diagnose nasal airway obstruction as part of a symptom of chronic allergies or sinusitis; however, it is essential to rule out a ...

European Annals of Otorhinolaryngology, Head and Neck Diseases, 2016 Nasal obstruction is a very frequent symptom in children, with numerous etiologies. Clinical diagnosis is straightforward, but general impact and rare etiologies should be explored for. Complementary examinations are guided by diagnostic orientation.
