Abstract :
An acceleration measurement system using the piezoelectric polymer poly(vinylidene fluoride) (PVDF) is described; furthermore a compensation of the polymer´s pyroelectric effects has been achieved. The main advantages of this sensor are its robustness and that it has a very low cost compared with other sensors. The measured sensitivity is 1.071 V m/sup -1/ s/sup 2/.
