Impact of Physical Deformation on Electrical Performance of Paper-based Sensors

Joanna M. Nassar, and Muhammad M. Hussain


We report on investigation of the mechanical properties of paper electronics (printed and made out of paper). One key objective of such paper electronics is to achieve ultra-flexibility. Therefore, it is important to understand electrical functionality and reliability of paper electronics under various physical (mechanical) deformation. Here we show, the general mechanical properties of the cellulose paper used and its electrical behavior under applied strain, tackling the main effects that need to be identified when building paper based systems, from product performance and stability perspective. An overview of the stress-strain behavior of silver ink on paper is discussed and then we tackle a more specific analysis of the performance variations of paper sensors made with recyclable household materials when exposed to various mechanical conditions of tensile and compressive bending. This study is important for developing stable wearable sensors for incorporation in Internet of Everything (IoE) applications.
