A piezoresistive sensor based on ultralight and superelastic aerogel is reported to fabricate MXene/reduced graphene oxide (MX/rGO) hybrid 3D structures and utilize their pressure-sensitive characteristics. The MX/rGO aerogel not only combines the rGO’s large specific surface area and the MXene’s (Ti3C2Tx) high conductivity but also exhibits rich porous structure, which leads to performance better than that of single-component rGO or MXene in terms of the pressure sensor. The large nanosheets of rGO can prevent the poor oxidization of MXene by wrapping MXene inside the aerogel. More importantly, the piezoresistive sensor based on the MX/rGO aerogel shows extremely high sensitivity (22.56 kPa–1), fast response time (<200 ms), and good stability over 10 000 cycles. The piezoresistive sensor based on the MX/rGO hybrid 3D aerogel can easily capture the signal below 10 Pa, thus clearly testing the pulse of an adult at random. Based on its superior performance, it also demonstrates potential applications in measuring pressure distribution, distinguishing subtle strain, and monitoring healthy activity.

用于压阻传感器的3D协同MXene /还原氧化石墨烯气凝胶
据报道，基于超轻和超弹性气凝胶的压阻传感器可制造MXene /还原氧化石墨烯（MX / rGO）混合3D结构并利用其压敏特性。MX / rGO气凝胶不仅结合了rGO的大比表面积和MXene（Ti 3 C 2 T x）的高电导率，而且还表现出丰富的多孔结构，因此其性能优于单组分rGO或MXene。压力传感器的 rGO的大纳米片可以通过将MXene包裹在气凝胶中来防止MXene的不良氧化。更重要的是，基于MX / rGO气凝胶的压阻传感器显示出极高的灵敏度（22.56 kPa –1），快速响应时间（<200 ms），以及超过10000个周期的良好稳定性。基于MX / rGO混合3D气凝胶的压阻传感器可以轻松捕获低于10 Pa的信号，从而清晰地随机测试成年人的脉搏。基于其卓越的性能，它还展示了在测量压力分布，区分细微应变以及监测健康活动方面的潜在应用。
