Large area matrix of MXene/MoSe2 nanohybrid-based flexible piezoresistive pressure sensors for artificial e-skin application

In this study, a MoSe2/Ti3C2Tx nanohybrid-based fabricated flexible physical sensor demonstrates an elevated pressure sensitivity of 14.70 kPa(-1) and a highly robust nature withstanding up to similar to 2500 cycles. The fabricated pressure sensor's underlying transduction mechanism is elucidated by exploiting the inherent piezoresistive effect and the variation of the Schottky barrier height unveiled by the MoSe2/Ti3C2Tx interface with the assistance of comprehensive band structures that are appreciated by ultraviolet photoelectron spectroscopy. Also, sensors were employed as a 7 x 7 sensor matrix with a large area for tactile sensing and incorporated onto the volunteer hand to determine the artificial skin application.
