Compressible AgNWs/Ti3C2Tx MXene aerogel-based highly sensitive piezoresistive pressure sensor as versatile electronic skins

AgNWs/Ti₃C₂Tx MXene aerogel with well-aligned layer structure was prepared by a directional freezing strategy, and applied to fabricate piezoresistive pressure sensor, which has ultrahigh sensitivity (645.69 kPa⁻¹) and low detection limit (1.25 Pa).
