Infraestruturas são formas materiais que permitem trocas por meio do espaço. Elas são redes físicas através das quais mercadorias, ideias, lixo, energia, pessoas e capitais financeiros circulam. Neste artigo, mapeio a literatura antropológica que busca teorizar a infraestrutura a partir da biopolítica, dos estudos de ciência e tecnologia e das teorias de tecnopolítica. Também examino outros aspectos das infraestruturas que proporcionam diferentes significados e estruturas políticas por meio das dimensões estética, sensorial, do desejo e da promessa.The politics and poetics of infrastructureAbstract: Infrastructures are material forms that allow for the possibility of exchange over space. They are the physical networks through which goods, ideas, waste, power, people, and finance are trafficked. In this article I trace the range of anthropological literature that seeks to theorize infrastructure by drawing on biopolitics, science and technology studies, and theories of technopolitics. I also examine other dimensions of infrastructures that release different meanings and structure politics in various ways: through the aesthetic and the sensorial, desire and promise.Keywords: Infrastructure, Technopolitics, Biopolitics, Aesthetics, Technology.
