For the mimicry of human skin, one of the challenges is how to detect and recognize different stimulus by electronic device, while still has the ability of skin self-recovery at the same time. Because of the excellent elasticity and flexibility, strong self-healing ability, in this paper, we reported a bifunctional self-healing e-skin with polyurethane (PU) and polyurethane@multiwalled carbon nanotubes (PU@CNT) as the sensing materials by integrating a resistance temperature sensor on top of a capacitive pressure sensor on the same flexible cellulose nanocrystals@ carboxylated nitrile rubber@polyethylenimine (CNC@XNBR) substrate. Studies found that each type of sensor exhibited fast and superior response to only the target stimuli. Meanwhile, due to the self-recovery properties of PU and CNC@XNBR, as-fabricated e-skin has the self-healing ability after damage and remains excellent sensitivity to temperature and pressure after healing. A 5 x 5 device array was also fabricated, which can simultaneously image the pressure and temperature distribution.
