A team of researchers from Shanghai Xiao Tong University has found that the human hand can be used as a powerless infrared radiation (IR) source in a wide range of applications.
In their paper published in the Proceedings of the National Academy of Sciences, the group notes that the human hand naturally emits IR and they demonstrate that radiation can be captured and used.
The human body emits light in the invisible IR range, including hands. This source of radiation, the researchers noted, could possibly be captured and used in applications ranging from signal generation to encryption systems.
He further mentioned that because the hand has many fingers, the IR that emits it can be considered multiplexing.
IR is a form of electromagnetic radiation – its wavelengths are longer than visible light, which is why humans cannot see them. Prior research has shown that the human body emits this type of radiation due to body heat.
Electromagnetic radiation carries it with radiant energy, and its behavior is classified as both a quantum particle and a wave. Prior research has also shown that electromagnetic radiation can be used in a wide variety of applications, including microwaves, radios, and medical imaging devices.
And infrared light, in particular, enables night vision goggles, spectroscopy devices and medical devices to treat burn victims. In this new effort, researchers have found that a very small amount of IR emitted from the human hand is sufficient to be used in various devices.
The team started by creating a device that was able to separate one-handed emitted IR from ambient IR. They then sprayed a low-reflective material based on aluminum and found that together, the two devices could be used to encrypt messages at ambient temperature.
He noted that when a human hand was used as a light source for the device, its IR emissions were reflected by all regions, including those with high IR – high increases in IR led to the device. Allowed to isolate IR radiation, providing a means. For creation in a decryption process.
Researchers suggest that their devices prove that man-made IR is sufficient for manufacturing IR-based devices. He also noted that his device could be modified to allow fingers to be used as encryption keys.

According to a report by Inverse, a team of engineers from China is developing a new method to use infrared radiation emitted from human hands to decrypt secret data and create passcodes.
In a paper published on Monday, April 5 in the National Academy of Sciences magazine Proceedings, the team described how hand-infrared radiation (essentially the heat emitted by our bodies) could be allowed to host safety applications.
Their method would be controlled by the human body, which would allow for a power-free, multifunctional decryption system, which would not be obsolete – until we finally merged with AI and left our bodies behind.
The concept focuses on the light given by infrared radiation – invisible to the naked eye, radiation is already used by technologies such as night vision goggles that allow the wearer to see animals or humans in the dark through their heat signature Please allow.
