Suction cups with integrated tactile sensors demonstrate great potential for the implementation of bioinspired tactile-based underwater manipulation strategies. However, the sensitivity of existing sensorized suction cups is limited under small external loads. In this project we take inspiration from the cuttlefish to design, manufacture and validate a suction cup with integrated highly sensitive tactile sensor. Cuttlefish suckers comprise many receptors for sensing. Moreover, there are many papillae covering its sucker rim. Previous studies have shown that the papillae structures can enhance the sensitivity of the sensors. Herein, we hypothesize that the papillae can also enhance the sensing sensitivity of the resistive sensor-integrated suction cup.
