The wearable intelligent electronic product similar to electronic skin has a great application prospect. However, flexible electronic with high performance pressure sensing functions are still facing great challenges. In this paper, the highly sensitive flexible electronic skin (FES) based on the PVDF/rGO/BaTiO₃ composite thin film was fabricated using the near-field electrohydrodynamic direct-writing (NFEDW) method. The PVDF/rGO/BaTiO₃ composite solution was directly written on flexible substrate by the NFEDW method to fabricate FES with micro/nano fiber structure, which has the function of sensing pressure with high sensitivity and fast response. The surface morphology and microstructure were characterized by SEM, AFM, and optical microscope in detail. The fabricated FES has high sensitivity (59 kPa⁻¹) and faster response time (130 ms). FES has been successfully applied to the detection of human motion and subtle physiological signals. The experimental results show that FES has good stability and reliability. FES can recognize human motion, and it has a broad application prospect in the field of wearable devices.

类似电子皮肤的可穿戴智能电子产品应用前景广阔。然而，具有高性能压力传感功能的柔性电子仍然面临着巨大的挑战。在本文中，使用近场电流体动力学直写（NFEDW）方法制备了基于 PVDF/rGO/BaTiO ₃复合薄膜的高灵敏度柔性电子皮肤（FES）。PVDF/rGO/BaTiO ₃将复合溶液通过NFEDW方法直接写入柔性基板上，制成具有微/纳米纤维结构的FES，具有高灵敏度和快速响应的传感压力功能。通过扫描电镜、原子力显微镜和光学显微镜对表面形貌和微观结构进行了详细表征。制造的 FES 具有高灵敏度 (59 kPa ^-1 ) 和更快的响应时间 (130 ms)。FES 已成功应用于人体运动和细微生理信号的检测。实验结果表明，FES具有良好的稳定性和可靠性。FES可以识别人体运动，在可穿戴设备领域有着广阔的应用前景。
