a The sensor is designed for breathability, flexibility, and comfort. b MXene nanosheets are prepared by etching MAX phases with LiF and HCl, followed by delamination. c Electrospinning TPU creates a fibrous membrane, and serpentine electrodes are screen-printed for conductivity. d The MXene sensing layer is made by depositing nanosheets onto a substrate. e The MF sensor is assembled by combining the electrode substrate with the MXene layer for pressure and strain detection. f The 4 × 4 sensor monitors palm pressure distribution. g The 4 × 4 array detects pulse waves on the wrist, generating BP waveforms. h BP prediction involves pulse signal collection, feature extraction, and accuracy validation with sphygmomanometer measurements.
