High-performance stretchable and wearable electronic skins (E-skins) with high sensitivity and a large sensing range are urgently required with the rapid development of the Internet of things and artificial intelligence. Herein, a reduced graphene oxide (rGO)/polyaniline wrapped sponge is prepared via rGO coating and the in situ synthesis of polyaniline nanowires (PANI NWs) on the backbones of sponge for the fabrication of pressure sensors. From the as-prepared flexible sensor, tunable sensitivity (0.042 to 0.152 kPa−1), wide working range (0–27 kPa), fast response (∼96 ms), high current output (∼300 μA at 1 V), frequency-dependent performance reliable repeatability (∼9000 cycle) and stable signal waveform output can be readily obtained. In addition to tiny physiological activities (voice recognition, swallowing, mouth opening, blowing and breath), robust human motions (finger bending, elbow movement and knee squatting–arising) can also be detected in real-time by the flexible sensors based on rGO/polyaniline wrapped sponge. All the results demonstrate that the flexible pressure sensor based on the functional-sponge is a promising candidate for healthcare monitoring and wearable circuitry in artificial intelligence.

基于rGO /聚苯胺包裹的海绵的柔性压力传感器，灵敏度可调，可用于人体运动检测†
随着物联网和人工智能的快速发展，迫切需要具有高灵敏度和大传感范围的高性能可伸缩电子皮肤（E-skin）。在此，通过rGO涂层和在海绵的骨架上原位合成聚苯胺纳米线（PANI NW）来制备还原的氧化石墨烯（rGO）/聚苯胺包裹的海绵，用于制造压力传感器。通过准备好的柔性传感器，可调节灵敏度（0.042至0.152 kPa -1），宽的工作范围（0–27 kPa），快速的响应（〜96 ms），高电流输出（在1 V时为〜300μA），与频率相关的性能，可靠的重复性（〜9000个周期）和稳定的信号波形输出容易获得。除了微小的生理活动（语音识别，吞咽，张开嘴，吹气和呼吸）之外，还可以通过基于rGO的灵活传感器实时检测强大的人体运动（手指弯曲，肘部运动和蹲下膝盖）。 /聚苯胺包裹的海绵。所有结果表明，基于功能海绵的柔性压力传感器是人工智能中医疗保健监测和可穿戴电路的有前途的候选者。
