## Summary

Ali Rohafza, CEO and co-founder of Altered Carbon, explains how his company developed digital vapor detection sensors that replicate the human nose to identify and fingerprint smells. He details the technology's origin at the Bristol Robotics Laboratory, the use of graphene-based sensors for low-power operation, and the challenge of creating standardized testing methods for mass production. Rohafza discusses key applications in food spoilage detection, industrial safety, and potential future uses in agriculture and medical diagnostics.
