Herein, a simple and low‐cost fabrication method for flexible piezoelectric pressure sensors with hierarchical structures over large areas is presented. First, polyvinylidene fluoride (PVDF) and barium titanate (BaTiO3, BTO) composite membranes are fabricated through near‐field electrospinning, and the hierarchical structured membrane (HSM) is obtained by spreading the flat membrane on the designed...
Human astrovirus (HAstV) is a single‐stranded, positive‐sense RNA virus and is the leading cause of viral gastroenteritis. However, despite its prevalence, astroviruses still remain one of the least studied enteroviruses. In this study, we sequenced 11 classical astrovirus strains from clinical samples collected in Shenzhen, China from 2016 to 2019, analyzed their genetic characteristics, and deposited...
