I would like to design temperature and pressure Graphene-based sensors using the laser scribing method (LIG). How can I adjust the laser machine (carbon dioxide laser machine) so that sensors will act as temperature and pressure sensors? In other words, How can I control the laser parameters ( laser wavelength, speed, beam size, duty cycle,..etc) so that the sensor will behave as a Temperature/ pressure sensors? what is the range of each parameter that should be used to manufacture these two sensors?
