| Abstract: | With the help of Taylor expansion of dualistic fimetion, the sensitivity of strain and temperature of piezoresistive transducer is given and the formula of crossed sensitivity of strain v/s temperature is also presented. The physical meaning is expounded and the crossed sensitivity is estimated combining with practical measuring data. The method offers instructive significance in using transducers and for compensation. |
