Flexible electronic skin has tactile perception similar to human skin, and has been widely used in the field of human-computer interaction. The flexible electronic skin is designed and fabricated using poly-vinylidene fluoride (PVDF), reduced graphene oxide (rGO), and room temperature vulcanised (RTV) silicone rubber. Performed tests reveal that RTV silicone rubber has good piezoelectric properties and can increase the output voltage of the electronic skin. The effect of the number and spacer thickness of PVDF/rGO films on the voltage are studied, and the optimal structure is determined accordingly. Obtained results show that the proposed electronic skin has a wider linear working range at low frequencies, the peak voltage reaches 8.80 V. Meanwhile, good flexibility and high sensitivity are obtained, which can realise the measurement of static and dynamic pressures. The proposed electronic skin is used to monitor and identify the muscle activity caused by pulse and breathing. [ABSTRACT FROM AUTHOR] |
