The pursuit of efficient and accurate human–computer interface design urgently requires high-performance sensors with pressure sensitivity, a wide detection range, excellent cycling stability. Herein, biomimetic honeycomb-like Ti3C2Tx MXene/bacterial cellulose (BC) aerogel negative Poisson's ratio (ν = −0.14) synthesized from the bidirectional freeze-drying method is used as active material for flexible sensor, which exhibits high sensitivity (20.14 kPa–1), fast response time (100 ms), mechanical durability (5000 cycles), low limit (responding to grain rice weighing about 0.022 g). Moreover, when assembled into sandwich-structured bending sensor layer at just 0.8 mm in thickness, aerogel-based device has angular range (2.7–156.3°), (0.47 deg–1), good robustness, proving outstanding electromechanical performance. Significantly, smart glove consisting five fixed proximal knuckles circuit board signal processing unit was designed identification shape, demonstrating its promising applications field interaction.
