Multipurpose Sensing Platform Based on Laser-Reduced Graphene Oxide for Flexible and Ubiquitous Electronics

We present a versatile sensing platform, intended for ubiquitous and flexible electronics sensing applications based on the controlled reduction of Graphene Oxide by a laser diode. This technique allows the fast and ecological production of reduced Graphene Oxide without the need of expensive lithography masks. We will show results of the conductivity calibration by the photothermal reduction power, as well as the electrical characterization of the bare samples. Finally, a simple demonstrator of the platform based on an ultra-low power System on Chip (SoC) is introduced.This work has been supported by the Spanish Ministry of Educaton, Culture and Sport (MECD) through the pre-doctoral grant FPU16/01451, the University of Granada through the scholarship “Initiation to Research“, the National Excellence Research Project TEC2017-89955-P and the European Union by the fellowship H2020-MSCA-IF-2017 794885-SELFSENS
