Flexible thin-film sensors can be produced with different sizes of shapes due to their extremely high flexibility and expansibility.Through the array arrangement,the integrated sensor module with large size,diversity and real-time data characteristics can be designed.However,there are still challenges in the method of real-time data acquisition for large-size array flexible thin films.This paper is based on STM32 microcontroller unit(MCU) and a 4 ×4(scalable)array flexible thin-film.By STM32 control,the array type fast scanning is realized,the signal source is located in real-time and fastly the pressure change value in the thin-film unit is fed back.
