In recently at the 250th session of the American chemical society (ACS) at the national meeting of the American Wright -
Paterson air force base, air power laboratory showed off their latest flexible mixed materials of electronic technology. The
researchers believe that the future of ultra-thin elastic high-performance electronic products will gradually replace the rigid
printed circuit boards, which can be used in military and daily life.
Benjamin J. Levi, Dr. of the laboratory said: " the mix of electronic technology, which can fully mix traditional flexible
electronic components, high-performance electronic products and new method of 3 d printing, metal, polymer can be
integrated into the "ink" and organic material, the whole system electronically connected together. With this technique,
hundreds of nano-thick silicon chips can be made into a substrate that is as soft as plastic and can bend and even fold.”
In order for electronics to bend or stretch after assembly, Patterson's team used a liquid gallium alloy as an electrical
interconnection material, Levi said. "While these liquid alloys can be oxidized into useless materials in a matter of minutes,
the team has found a way to reduce this process," he said. Ultra-thin foldable materials made with special methods allow
the circuit to fit into the material space, even fit in complex curved surfaces such as airplane wings or human skin.
In aircraft, this hybrid flexible system can be used to monitor pressure and stress; The pilot's health information can be
reported to the ground staff through a miniature embedded antenna. Wearable biosensors can measure fatigue and potential
cognitive problems in real time, while measuring heartbeat, sweating levels, temperature and other vital signs.
Levi disclosed, another military application is to place it on the "bunker buster bomb, preliminary tests show that flexible
circuits can be released in a bomb out of the plane, after contact with the ground early to remain active and detonated
weapon.
In daily life, Levil predicts that this flexible electronic system can monitor the construction conditions of Bridges and other
infrastructure in real time. In the medical application, the body indicator of the athletes can be feedback or the vital signs of
real-time monitoring of patients.
