FCJ-219 The Sensed Smog: Smart Ubiquitous Cities and the Sensorial Body

Jussi Parikka
2017 Fibreculture Journal  
These two threads, sensors and the sensed city, lead to a conceptual argument that suggests to look at the technologies of smart city as an entanglement of the materiality and data.  ...  Smart cities carry forward their earlier technological legacy in infrastructure and often also in terms of the residual air pollution, like photochemical smog.  ...  Management of the environment means also management of the data about the environment. Any environment includes also the data about itself, the wider media ecology.  ...
