Abstract
This work is inspired by the 'Dome Pressure Receptors' (DPRs), which are scattered on the skin of crocodiles, assisting them to locate the origin of disturbance, both on water surface [1] and inside the water [2]; thereby enabling them to hunt preys even in dark environment and turbid waters. In this study, a dome structure embedded with piezoelectric pressure sensors is constructed, which carries out the mechano-receptive function of DPRs for direction detection. The experimental results demonstrate that the proposed dome structure could determine the direction of the origin of a disturbance.
