Development of flexible contact ultra conductor based on copper and graphene stamping

Agriculture is part of Mexico's main activities due to its natural richness in soil and water resources. However, there are technological and economic limitations that restrict its optimal performance, such as the soil fertility study, which is normally not accessible for this segment. In order to address this problem, we seek to develop a practical, portable and low-cost alternative to be used without the need for advanced technical knowledge.

Objective

Design, develop and characterize an ultra conductive flexible electrode using copper as a base for deposition of multilayer graphene and subsequent stamping of this to improve and modular conductive properties. The intended application includes the detection and quantification of essential chemical species in the analysis of soil for cultivation through the manufacture of a high sensitivity sensor.

Additional information: Active collaboration with Simon Fraser University (SFU) in Canada. The project is part of the Nanotechnology and Device Design Group. Knowledge is required in the area of ​​band theory, surface engineering, deposition by physical evaporation, electrical characterization and quantum driving phenomena.
