Summary: By using a single-electrode-mode triboelectric nanogenerator (S-TENG), a fully elastic E-skin capable of sensing both normal pressure and shear force simultaneously has been developed. The pressure sensor shows high linearity and sensitivity in the low-pressure region, while the multidimensional force sensor utilizes two S-TENGs to detect normal pressure and shear force separately. When mounted on a robotic manipulator, the sensor can recognize changes in grabbing state, suggesting potential applications in robotics, human-robot interactions, environmental awareness, and object recognition.
