报道了一种基于超轻和超弹性气凝胶的压阻传感器，用于制造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NIXene（Ti 3C 2 Tx）的高电导率，而且还具有丰富的多孔结构，这导致在压力传感器方面比单组分rGO或MXene的性能更好。大的rGO纳米片可以通过将MXene包裹在气凝胶内部来防止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））、快速的响应时间（
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 NIXene'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 (
