Gradient electric field and gradient drug concentration combined testing device, method and system

The invention provides a gradient electric field and gradient drug concentration combined test device, method and system. The device comprises an external circuit and a combined test chip, the joint test chip comprises a porous micro-cell culture chamber and conductive parallel plates mounted on each side surface of the porous micro-cell culture chamber, and an external circuit is connected with the conductive parallel plates on any two adjacent sides of the porous micro-cell culture chamber; the external circuit is used for outputting a specific square wave signal so as to generate two superposed alternating electric fields in different directions on the porous micro-cell culture chamber, so that the porous micro-cell culture chamber is in a gradient electric field; and the porous micro cell culture room is used for loading tumor cells and chemotherapeutic drugs with gradient concentration. The device can simultaneously meet the requirements of drug screening and electric field resistance evaluation by apply
