Abstract

Thermocouples are used in a variety of applications for temperature measurement and monitoring. Here, we demonstrate an HB/6B graphite paint-based thermocouple to design temperature sensors on commercially available Xerox paper using two different grades of graphite. The difference in Seebeck coefficients in different grades of graphite facilitates the successful fabrication of a thermocouple. These simple, cheap, environment friendly, biodegradable single-material thermocouples demonstrated a persistent and reliable sensitivity of ~ 27 μV/K after 300 bending cycles. In addition, the output voltage variation has also been recorded after 300 bending cycles as a function of time to demonstrate response with respect to temperature. The current study indicates that a piece of paper can be transformed into a thermal mapping device using only graphite paint patterns.

期刊介绍： The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications. Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field. A journal of The Minerals, Metals & Materials Society.
