Piezoresistive CNT based strain sensor- couldn’t able to get change in resistance with increase in stress

Please login with a confirmed email address before reporting spam

I am trying to model cnt strain sensor. I selected cnt as upper layer and pdms as bottom layer. Applied solid mechanics and electric current physics(ground the bottom layer and applied terminal voltage 1V on upper layer). In the results resistance remains the same. When I am trying to do the same process using piezoresistive module it requires CNTs piezoresistive coupling matrix which I don’t have. The literature papers I reffered has not mentioned about the matrix and still able to get the result which I dont know how?
