Terahertz technology detection method for sensitivity of MXene-based pressure sensor array

The invention belongs to the technical field of sensor detection, and particularly relates to a terahertz technology detection method for the sensitivity of an MXene-based pressure sensor array, and the method comprises the following steps: S1, terahertz time-domain spectrum detection: measuring the terahertz transmission characteristics of an MXene material; and S2, a terahertz imaging step: using a terahertz imaging technology to obtain an array arrangement mode of the MXene-based flexible pressure sensor array. Through the terahertz imaging technology and the terahertz time-domain spectroscopy (THz-TDS) technology, when the array sensor is irradiated by terahertz light, the array arrangement mode and the condition that the conductivity changes along with the stress can be obtained at the same time, and due to the fact that the photon energy of terahertz is very low, the conductivity of the terahertz light is not changed along with the stress. Therefore, the use performance of the array sensor sample is not
