Application of biomimetic honeycomb Ti3C2Tx MXene/bacterial cellulose aerogel prepared by bidirectional freeze-drying method in automobile navigation system

The researchers used a bidirectional freeze-drying method to synthesize a biomimetic honeycomb Ti3C2Tx MXene/bacterial cellulose (BC) aerogel with a negative Poisson's ratio (ν=−0.14), which can be used as an active material for flexible pressure sensors. This sensor has great application potential in car navigation systems and can be used to monitor the direction and speed of a car, thereby improving navigation accuracy.
