Quartz transducers has been widely used to sense stress pulse profiles.The impact loading response of shorted quartz transducers with various guard-ring-widths to chip-thickness ratios（w/d） are investigated.The experimental results show that the dynamic responses of shorted quartz transducers are very similar and the piezoelectric coefficient depends linearly on impact stress.Range of the current ramping show almost constant with w/d when w/d is more than 1.4

but range of the current ramping increases a lot when w/d is less than 1.4 due to the fringe effect.So that shorted quartz transducer with 1.4 w/d can be applied in practical measurement.
