Nanomaterial-Based Macroscale Printable Flexible Sensors
In this study, we propose printable sensor sheets using nanomaterial-based inorganic and organic solutions4,5. Especially here printable strain and temperature sensors for different kinds of applications are demonstrated on flexible substrates such as silicone rubber, PET, etc. by using a screen printer and a laser patterning technique. As a proof-of-concept, macroscale, low-cost sensor sheet in order to monitor the strain and cracking information from infrastructures and vehicles were fabricated on a silicone rubber using the screen printing method. The results exhibited that high sensitivity (~59%/Pa) strain sensor detected <10 µm displacement on a wall. This suggests that high sensitive low-cost sensor sheet can be used for the infrastructure monitoring system as an example.
Furthermore, we will also talk about our recent results of a self-cleaning passivation layer for the flexible devices and more sensor applications such as an artificial electronic whiskers4 and smart bandage5.
Our proposed printable flexible sensors may be applied to a variety of applications such as human interfaces, infrastructures, and vehicles.
