(a–c) Sensor architecture — a flexible, multi-layer textile insert containing freeze-dried reaction wells that activate on liquid exposure. (d–g) Four genetic-circuit designs (constitutive expression, transcriptional regulation, a toehold switch, and a riboswitch) with their colorimetric readouts over time. Source: Nguyen, P.
