	In this work, we report a paradigmatic shift in bioinspired microchannel heat exchanger design\&nbsp;toward its integration into thin film wearable devices, thermally active surfaces in buildings, photovoltaic devices, and other thermoregulating devices whose typical cooling fluxes are below 1 kW m-2. The transparent thermoregulation device is fabricated by bonding a thin corrugated elastomeric film to the surface of a substrate to form a microchannel water-circuit with bioinspired unit cell geometry. Inspired by the dynamic scaling of flow systems in nature, we introduce empirically derived sizing rules and a novel numerical optimization method to maximize the thermoregulation performance of the microchannel network by enhancing the uniformity of flow distribution. The optimized network design\&nbsp;results in a 25\% to 37\% increase in the heat flux compared to non-optimized designs. The study demonstrates the versatility of the presented design\&nbsp;and architecture by fabricating and testing a scaled-up numerically optimized heat exchanger device\&nbsp;for building-scale and wearable applications.
