Multifunctional wearable electronic sensors exhibit significant potential for applications in health management, motion tracking, intelligent healthcare, etc. In this study, we developed a novel assembly method for a polymeric silver nanowire (Ag NW)/transition metal carbide/nitride (MXene) @Loofah device using a facile solution dip-coating technique. During the pretreatment phase, the loofah was conditioned with polydiallyldimethylammonium chloride (PDAC), promoting the self-assembly of MXene layers and bolstering device stability. Then, the Ag NWs/MXene@Loofah was packaged with polyurethane to form a piezoresistive pressure sensor, which demonstrated superior pressure-sensing capabilities and was adept at registering movements of human joints and even subtle pulses. The design strategy presents a novel and rational approach to developing efficient pressure sensors.
多功能可穿戴电子传感器在健康管理、运动跟踪、智能医疗等领域具有巨大的应用潜力。在本研究中，我们采用简便的溶液浸涂技术，开发了一种用于聚合物银纳米线（Ag NW）/过渡金属碳化物/氮化物（MXene）@丝瓜装置的新型组装方法。在预处理阶段，丝瓜用聚二烯丙基二甲基氯化铵（PDAC）进行处理，促进MXene层的自组装并增强装置稳定性。然后，将Ag NWs/MXene@丝瓜用聚氨酯封装，形成压阻式压力传感器，该传感器表现出卓越的压力传感能力，擅长记录人体关节的运动甚至细微的脉搏。该设计策略为开发高效压力传感器提供了一种新颖且合理的方法。
