“…When varying the strain from 20 to 100%, the sensitivity of the MXene/SF/TA pressure sensor remained almost unchanged, while the highest gauge factor was about 0.59. To improve the sensitivity of the MXene/SF based sensor, Yang et al [ 176 ] fabricated an oriented Ti 3 C 2 T x /SF/hyaluronic acid (HA) hydrogel. The resulting gauge factor steadily increased from 4.5 at 5% strain to 11.3 at 80% strain, while non-oriented MXene/SF/HA hydrogel only reached a maximum gauge factor of 5.7 (65% strain).…”
