Laser-scribed graphene (LSG) for sensors

https://phys.org/news/2023-10-laser-scribed-graphene-sensors.html

"detect pressure and mechanical strain, chemicals (glucose, dopamine, proteins, heavy metals and organic pollutants, gas), temperature and humidity... irradiate carbon precursors and generate graphene by in-situ scribing in minutes... LSG's wide detection range, high sensitivity, fast response, high surface area, high thermal stability, high electrical conductivity, simple and efficient fabrication process, selective and localized reduction, precise and fast patterning, and absence of masks and additional chemicals"
