The concept of superhydrophobicity, also known as the “lotus effect,” refers to the ability of certain surfaces to repel water. This phenomenon is observed in nature, where some plants and animals have evolved to resist water and dirt to survive. While this property is crucial for aquatic and some terrestrial species, it is not limited to them. Many animals, such as insects, amphibians, and birds, have developed ways to repel water to prevent drowning, stay dry, and maintain body heat. Researchers at Thales are studying how to replicate these natural phenomena to create multifunctional surfaces with superhydrophobic properties, which can be used in optical systems, such as high-performance video cameras in vehicles. These durable surfaces can withstand extreme humidity and maintain optimal functionality, providing a key operational advantage. The team is also working on antireflective surfaces, inspired by the Greta oto butterfly, which can minimize reflection and glare. The applications of these technologies are vast, and researchers are eager to explore their potential in various fields, from security systems to optical systems.
Like a duck gliding effortlessly through the water, our innovations at Thales flow smoothly and unimpeded.
