Development of stretchable strain sensor using elastic membrane coated with conducting material

Recently, much attention has been drawn to stretchable or flexible electronic sensors for measuring input pressure or deformation on movable and arbitrarily shaped objects. In this research as a preliminary study for developing a new stretchable stain sensor, we designed an integrated experimental system for measuring simultaneously change of strain, stress, and conductance of a stretchable membrane and evaluated the performance of our stretchable and conductive membrane as a strain sensor. The results show that the developed membrane has a great potential to measure strain and stress applied to the membrane with high sensitivity.
