Inspired by the ubiquitous lateral-line system of fish which plays an essential role in flow sensing and object detection, this paper presents a new sensor consisting of a radial field piezoelectric diaphragm in d33 mode and a high aspect ratio pillar. Finite element analysis was conducted to simula...
