摘　　要：虽然应变式电阻压力传感器得到广泛应用,但对传感器本身的灵敏度的测试却鲜有研究.为此,提出了测量应变式电阻压力传感元件灵敏度的方法,并设计了测量电路,对其灵敏度进行了理论分析、推导和实验测量与验证.该方法有助于学生深入了解该传感器的性能及其应用技术.Although strain resistance pressure sensors were widely used,the sensitivity of the sensors themselves had rarely been studied.Now,A method for measuring the sensitivity of strain resistance pressure sensors was proposed,and a measurement circuit was designed.The theoretical analysis and derivation,the experimental measurement and verification were carried out.This method could help students deeply understand the performance of the sensor and its suitability.
