  Efficient energy harvesting, conversion, and recycling technologies are
crucial for addressing the challenges faced by modern societies and the global
economy. The potential of harnessing mid-infrared (mid-IR) thermal radiation as
a pervasive and readily available energy source has so far no been fully
exploited, particularly through bioinspiration. In this article, by reviewing
existing photon-based strategies and the efficiency of natural systems in
harnessing light and thermal radiation, I highlight the promising role of
bioinspiration in enhancing energy capture, conversion, and recycling. Natural
photonic structures found in various organisms, including insects, birds, and
plants, exhibit sophisticated optical properties that can be leveraged for
energy-efficient applications. These developments pave the way for future
research and innovation in bioinspired energy solutions. Ultimately, they
contribute to the pursuit of a sustainable and environmentally conscious future
by harnessing the beauty of nature's designs to meet humankind's energy needs.
