Abstract

Biodegradable food packaging gains a lot of significance for the sake of environment, and increased prohibition of using plastic package. Further, the functionality of sensing food status is in great importance because of health and environmental issues. Here, we report laser-induced graphene based on paper for smart food decay sensor. Direct irradiation of continuous-wave laser converts any type of commercially available papers into effective laser-induced graphene (LIG). Paper-based LIG electrodes have enough conductivity to be applicated as the electrical circuit with the sensibility on certain aspects. LIG electrode could detect either temperature alteration or gaseous chemical compounds that ejects from spoiling food. As a proof-of-concept, we developed the smart food decay sensor based on LIG-on-paper with detecting temperature of food and food decaying gas, which information is able to directly sent to users’ mobile devices through Wi-Fi network. Herein, we believe that the smart food decay sensor could contribute on environment as green electronics, and food safety with preservation of food.
