“The army becomes invisible as a calmar”: this military technology erases the soldiers of the radars and the field of vision

The technological advances inspired by nature continue to push the limits of what is possible. Consequently, and The recent study on calmars is a perfect example. For example, Thanks to DARPA and Air Force funding, researchers have exploited the secrets of cephalopods to potentially revolutionize military camouflage. However, A team from the University of California. In “the army becomes invisible calmar”: addition, Irvine, in collaboration with the Navy Biological Laboratory, has managed to observe the cells that allow calmars to change color at will. Furthermore, These discoveries are not only fascinating, they open the way to innovative applications in the field of defense.

Reflectin columns under the microscope – "the army becomes invisible calmar":

To understand the internal structure of the Iridophore Calmars cells. However, the researchers turned to an advanced technique called Holotomography. For example, This process, using high refraction indices of reflectin proteins, revealed the sinusoidal distribution of refraction indices within the iridophore cells. In addition, The images obtained showed that in each iridophore. columns of reflectin wrapthus confirming that these nanometric structures regulate the reflection and the transmission of light through the skin of the calmars. This discovery has provided the most detailed explanation to date on the rapid modulation of colors in these animals. showing how the columns twist and assemble.

A bio-inspired composite for adaptable camouflage – "the army becomes invisible calmar":

From this knowledge. the researchers have created a flexible composite that imitates and extends the optical range of calmars. This material combines reflectors from Bragg Sinusoidaux nanocolumaries. modeled on reflectin structures, with ultra -foster metal films to add infrared control. Under the effect of stretching or environmental changescomposite can change its appearance through visible and infrared bands. This makes “the army becomes invisible calmar”: it suitable for applications such as adaptive camouflage, multispectral screens and intelligent textiles. The manufacturing methods developed are evolving. and the team has already produced large sets that imitate, or even exceed, the natural optical capacities of calmars.

Potential applications in various fields

The design principles used for this “the army becomes invisible calmar”: material inspired by cephalopods could refine various devices ranging from lasers to optical fiber filters. including photovoltaic coatings and chemical sensors. According to Professor Gorodetsky, These adjustable optical materials inspired by cephalopods only tackle the surface of what is possible. Beyond military applications, these discoveries could also mark a significant advance in civic technologies, improving energy efficiency and optical communication.

The key role of marine biology in these discoveries

The Navy Biological. Laboratory has played a crucial role in understanding the coloring of cephalopods for over a century. Thanks to their expertise. the researchers were able to access animals and to deepen their studies on the structure of the iridophore fabrics. This partnership has highlighted aspects hitherto unknown to the cellular functioning of calmars. stressing the importance of interdisciplinary collaboration in scientific research. These discoveries illustrate how basic research can lead to disruptive technologies which transform various sectors.

While we continue to explore the possibilities offered by bio-inspired materials. it is clear that nature remains an inexhaustible source of innovation. The capacity of calmars to change color instantly has not only captured scientists, but has also opened new technological pathways. Faced with these advances, a question persists: what other wonders does nature have in store for the technologies of “the army becomes invisible calmar”: tomorrow?
