| Abstract |
Devices made from stretchable electronic materials are under huge interest as future application for wearable device in means for clothing or directly attached sensor. Such materials have typically been prepared by engineering elastomeric materials such as silicon.[1] Here we studied flexible and highly sensitive pressure sensor using thin films of carbon nanotube. CNT-PDMS nano composite based pressure sensors were tested on silver nanoparticle electrode array fabricated by printing method. Four composite films with different CNT concentration were fabricated by bar coating and 2mm pads were made from each of them. PDMS spacer is placed on the substrate and rigid PDMS top-plate is covered. By creating gap between electrode and CNT pad sensor using PDMS wall the sensitivity increases and electric read-out differs following the size of the composite and spacer design. Patterned CNT pad works as a sensor when it touches the electrode on the substrate when the top-plate is compressed. The silver nano particle ink was used to draw electrode by Sonoplot. By applying printing method, large area of substrate can be dispensed easily in short time with minimum error regardless to material. We used this platform to test continuous and discontinuous electric read-out. Further studies will be headed using BNNT as a piezoelectric sensor with similar design. |
