Magnetorheological elastomers（MREs） is a new type of smart materials.However

its piezoresistive property has seldom been studied and reported.Aiming at this problem

a test rig is developed.Some experimental studies on the MREs piezoresistivity have done under different circumstances

where the MREs were made by our own laboratory.The results show that the conductivity of the MREs respond sensitively to the applied pressure change

and a linear relationship between the resistivity of the MREs and the applied pressure can be observed within a certain pressure range.The thickness and the exerted magnetic field don’t have significant effect on the piezoresistivity of the MREs

as well as on its linearity.
