Nanocomposite-Enhanced Iontronic Tactile Sensor With High Sensitivity and Wide-Range Linearity for Underwater Robotic Manipulation.
Hydrostatic preload increases response nonlinearity and limits weak-force detection in underwater tactile sensing. Here, we present a nanocomposite-enhanced iontronic tactile sensor (NeITS) that combines high sensitivity with wide-range linearity through a coupled mechano-ionic mechanism. Hydrophobic SiO2 nanoparticles...
