A multi-channel system is designed to test the dynamic and static parameters of smart skin on the wing unit. Software and hardware design is completed, and research on the anti interference of the whole system has been carried out. Multi-channel signals of strain and vibration are allowed to be captured, and functions of charge amplifier, strain testing, oscilloscope, FFT, and data storage are integrated in the system. This system is designed to demonstrate high precision, great stability, the ability to operate for a long time in good condition, and the potential for wide application in fields such as aeronautics, astronautics, mechanical engineering, and medical treatment.
