11.Invited – Cellulose-based electrical sensor and their applications in healthcare and food systems

Firat Güder

Professor

Imperial College London

Celluose is a plant-derived abundant biopolymer that has been used in a variety of applications ranging from woven and non-woven fabrics to threads and food additives. Because cellulose-based sensors can be manufactured inexpensively, they are a hidden gem for producing large quantities of data that can be used for training machine learning models to provide insights and that would be difficult to obtain otherwise about complex systems. In this presentation, I will describe our work involving cellulose-based sensors to address wide range of problems in healthcare, plant phenotyping and soil analysis.
