The invention discloses a readout circuit of a resistive composite sensor array, and belongs to the technical field of a sensor. An array structure and a corresponding readout circuit are designed based on a dual-voltage feedback method for solving the problem of data reading speed of a two-dimensional array composed of resistive composite sensors each internally comprising even-numbered two-terminal resistive sensitive units. Resistance of two resistive sensitive units sensitive to different physical amounts in the same resistive composite sensor can be read through single detection, such that the data detection speed of the sensor array can be substantially improved, and at the same time, the complexity of a sensing system is effectively reduced. The invention further discloses a readout method of the readout circuit. Compared to the prior art, the detection speed is faster, some to-be-tested resistive sensitive units needing high-frequency detection can be detected multiple times in scanning of one time, and besides, the circuit complexity and the realization cost are lower.
