Sensory rehabilitation in pediatric patients with traumatic spinal cord injury is challenging due to the ongoing development of their nervous systems. However, these sensory problems often result in nonuse of the impaired limb, which disturbs impaired limb rehabilitation and leads to overuse of the contralateral limb and other physical or psychological issues that may persist. Here, we introduce a soft nanomembrane sensor-enabled wearable glove system that wirelessly delivers a haptic sensation from the hand with tactile feedback responses for sensory impairment assistance. The smart glove system uses gold nanomembranes, copper-elastomer composites, and laser-induced graphene for the sensitive detection of pressure, temperature, and strain changes. The nanomaterial sensors are integrated with low-profile tactile actuators and wireless flexible electronics to offer real-time sensory feedback. The wearable system's thin-film sensors demonstrate 98% and 97% accuracy in detecting pressure and finger flexion, respectively, along with a detection coverage of real-life temperature changes as an effective rehabilitation tool. Collectively, the upper-limb sensory impairment assistance system embodies the latest in soft materials and wearable technology to incorporate soft sensors and miniaturized actuators and maximize its compatibility with human users, offering a promising solution for patient sensory rehabilitation.
由于小儿创伤性脊髓损伤患者的神经系统仍在发育，因此对他们进行感觉康复具有挑战性。然而，这些感觉问题常常导致患者不使用受损肢体，这不仅干扰了受损肢体的康复，还会导致对侧肢体过度使用以及其他可能持续存在的身体或心理问题。在此，我们介绍一种基于软纳米膜传感器的可穿戴手套系统，该系统通过触觉反馈响应从手部无线传递触觉感受，以辅助感觉障碍康复。该智能手套系统利用金纳米膜、铜 - 弹性体复合材料和激光诱导石墨烯来灵敏检测压力、温度和应变变化。纳米材料传感器与薄型触觉致动器和无线柔性电子器件集成在一起，以提供实时感觉反馈。作为一种有效的康复工具，该可穿戴系统的薄膜传感器在检测压力和手指弯曲方面的准确率分别达到98%和97%，同时还能检测实际生活中的温度变化范围。总体而言，上肢感觉障碍辅助系统体现了软材料和可穿戴技术的最新成果，融合了软传感器和小型化致动器，并最大限度地提高了与人类使用者的兼容性，为患者的感觉康复提供了一个有前景的解决方案。
