I am currently trying to use Graphene for designing piezoresistive pressure sensor and as I saw in many of the previous threads the 'sigma0' , 'nd' terms pose a problem again..I could not understand how to properly solve this problem. The piezoresistive matrix segment turns yellow. Do I need to look these values up or do I need to do something else? Help.
