OUR SOLUTION
A miniaturized, flexible, sensitive and selective laser induced graphene based multifunctional-sensor chip for the detection of ions by combining different electrochemical principles. The LIG electrodes have been optimized with performance significantly surpassing the commercial electrodes. The developed sensors operate at environmentally relevant pH, demonstrate sensitivity from nM to µM range towards the target and are highly selective towards the target. The lifetime of the sensors has been efficiently tackled by integrating novel materials with signal processing strategies.
THE CHALLENGE
The idea of the project is the development of a real-time, portable, cost-effective electrochemical sensor system for remote monitoring of nutrients. The current systems are bulky to operate, require frequent intervention by humans, and have selectivity issues. The electrochemical sensors developed are based on a laser-induced graphene technology which offers a sustainable, economical and scalable production process with minimal use of resources compared to printing methods.
