The invention belongs to the field of electronic skin testing, and discloses an electronic skin comprehensive performance testing system. The system comprises a control module, an information transfer module and a performance testing module. The control module receives and processes an external instruction and delivers the same to a circuit for one thing, and for another receives a signal fed back from the information transfer module and processes, displays and saves the signal. The information transfer module includes a regulating circuit and a signal collecting and conditioning circuit. The regulating circuit is used for receiving an instruction from the control module and realizing the regulation of the performance testing module. The collecting and conditioning circuit is used for capturing and conditioning a signal of the performance testing module and feeding back to the control module. The performance testing module provides a testing environment for an electronic skin to be tested and leading out a testing signal. Through the invention, the test and characterization of the comprehensive performance of the electronic skin is completed collaboratively in a modular way, and the system is important test equipment for converting scientific research results in the field of flexible electronics into practical products.
