description	The invention relates to a signal quality evaluation method and system for a coplanar array capacitance sensor, belongs to the technical field of coplanar array capacitance detection, and solves the problem that the output signal quality of the coplanar array capacitance sensor cannot be effectively evaluated in the prior art. The signal quality evaluation method of the coplanar array capacitive sensor comprises the following steps: determining the number of effective electrode pairs and the number of invalid electrode pairs in a target coplanar array capacitive sensor according to a minimum detectable value of a capacitance measuring instrument and an array output signal of the target coplanar array capacitive sensor; calculating the electrode utilization rate of the target coplanar array capacitive sensor according to the number of the effective electrode pairs and the number of the invalid electrode pairs; and evaluating the quality of the array output signal of the target coplanar array capacitive sensor
