Paper Abstract

Recent development of 3D printing technologies would provide the variety of electronic devices including environmental sensors and bio-applications. Polymer-based sensors are compatible with human-body parts or prostheses to monitor the body status of surfaces or surroundings such as temperature, humidity, and pressure. Conventional 1D or 2D fabrication processes are effective for mass production. However, specific shapes such as curvy or 3D pathways would require the 3D printed sensors to expand the possible applications. In this study, organic temperature sensors fabricated on 3D printed surfaces are investigated to improve the device properties. 3D structures were fabricated using a DLP (direct light processing) 3D printer with photo-polymers. Sensor electrodes based on conductive carbon materials were printed on 3D shape structures. The resistances of organic temperature sensors were measured by the temperature variations. As the environmental temperature increased from 29 to 54℃, the resistance was decreased from 8.57 to 8.23 kΩ with the certain linearity, respectively. To further improvements, polymer composites comprising the inorganic nanoparticles were introduced to control the interfacial properties and the conductivity of composite carbons were improved.
