The paradigm of ubiquitous sensing radically changes the picture of our inhabited and yet-to-be-inhabited environments. The idea of the contemporary city as an entanglement of multiple actors, natures, and potentialities guides our exploration. This is a collection of research snapshots, tentative mappings of the state of sensing of and by our inhabited environments. As such, this is a partial delineation that is temporary by nature. It is, in part, the outcome of a doctoral course taught at the École polytechnique fédérale de Lausanne EPFL as part of the doctoral program on Architecture and Sciences of the City EDAR. Each contribution is composed of a blueprint and an accompanying essay. Some of them can be read like germinal manifestos; others _ convey the surprise researchers experience when reconsidering their object of study from an interconnected perspective. A guest contribution by Roc Albalat from Taller Estampa, alongside a short piece from the course instructors completes this small corpus, which will be grown and pruned through time.
