The osteophonic helmet marked the first step for this remarkable technology breakthrough, when French manufacturing company ELNO began testing the ability to amplify sound waves between soldiers, minimising the need to speak loudly. Soldiers activated the system simply pushing a button on their rifle and when they move their vocal cords, the waves are captured and sent to the other helmets. Then, the inner ears of the receiver interpret vibrations as perfectly audible words, even dozens of metres apart, they can communicate via discreet whispers.
The technology was shown off during Amazon Prime’s “Tomorrow’s World” by ELNO engineer Christopher Made.
He said last year: “It doesn’t work through the aerial transmission of sound waves that we generate when we speak, but simply catches the vibrations from the skull.
“It doesn’t transmit them to the eardrums, but directly to the inner ear.
“When the operator needs to be very discreet, he can speak very, very quietly.”
However, things have now gone a step further.
The series revealed: “These innovations are just the start, certain experts now want to go much further, allowing soldiers to speak without even opening their mouths, directly reading their comrades’ thoughts.
“Across the Atlantic, the US Army has long been modernising its infantry, the most prestigious labs in the country have undertaken new projects in which reality could soon catch up with sci-fi.
“This is the Albany Neuroscience Lab, 250 kilometres from New York, where Dr Gerwin Schalk and his colleagues have been studying the human brain for years.
“One goal is to perfect a communications system that works via telepathy”

“But the researcher went even further, using the software they decoded words imagined by the participants.
“With this impressive technology, it is now possible to dictate a word without pronouncing a sound.”
Dr Rittacio said: “We have found that certain brain functions have unique electrical signatures, locations and frequencies.
“So we can decipher not just the area of the brain, but we can understand certain frequencies and locations and how they change over milliseconds when a hand is being rotated.
“So we can not only map movement but the intention to move.”
Dr Schalk explained how the system is constantly improving.
He explained: “These words have particular phoning in them like the word “lead” has the phoning E.
“While the person is imagining, we can pick up the brain signal and the computer analyses them.”
