摘　　要：传统电工电子学实验以理论验证为主,缺乏综合性和应用性,文章提出了基于薄膜压力信号处理的综合实验设计,针对分布式薄膜压力传感器的阵列可变电阻存在交叉耦合的现象,设计输入和输出电路,依次得到受力下阵列中每一个电阻的单点压降,满足不同应用需求。该实验将电工电子学课程中丰富的理论知识综合运用,具有创新性和趣味性。Traditional experiments on Electronics in Electrical Engineering are mostly about theory verification, which are short of comprehensiveness and applicability. In this text, comprehensive experimental design on disposing pressure signal of thin film was put forward. Because array variable resistances of distributed thin film pressure sensor are cross coupling, input and output circuit were designed to solve it and to get voltage drop of every resistance under pressure. Abundant theoretical knowledge are employed jointly in this experiment, which has innovation and enjoyment.
