Engineers have developed a brand new way of triggering electronic circuits to self-destruct an improvement that may help protect sensitive data and also one day be used in biomedicine.
This ability to self-destruct is essential to electronics, where elements of a circuit board, or the whole circuit itself, may disintegrate or flake.
No are published so engineers in Cornell University and Honeywell Aerospace foresee environmental and biomedical applications .
According to Cornell, conductors that dissolve when water, requiring the presence of moisture are used by some passing electronic equipment. Other individuals disintegrate when they attain a specific temperature, requiring a heating component and power source to be attached.
The advance from Cornell is believed to utilize a silicon-dioxide microchip attached to your shell that has cavities filled with sodium and rubidium biflouride.
Ved Gund led the research also stated the reaction can be triggered remotely by using radio waves to open valves that maintain the chemicals.
“The encapsulated rubidium subsequently oxidises aggressively, releasing heat to vaporise the polycarbonate shell and then decompose the sodium bifluoride. The latter controllably releases hydrofluoric acid to etch off the electronic equipment,” said Gund.
Amit Lal, professor of electrical and computer engineering, said the exceptional architecture offers several advantages over previously made electronic equipment, for example, capacity.
“The stackable structure lets us create little, vaporisable, LEGO-like blocks to create arbitrarily large vanishing electronics,” said Lal.
The technology could be integrated into wireless sensor nodes for use in environmental monitoring.
“For example, vaporisable detectors can be deployed together with the internet-of-things platform for tracking crops or amassing data on moisture and nutrients, made to vanish as soon as they accomplish these tasks,” said Gund.
Gund Lal and Honeywell Aerospace have already been issued a patent for the technology, along with the SonicMEMS Laboratory is continuing to investigate ways the structure can be used toward other applications in addition to electronics.
“Our staff has also demonstrated using this technologies as a scalable micro-power momentum and electricity source, which may deliver high peak powers for robotic actuation,” said Lal.
Fabrication of the shell has been performed by Christopher Ober, professor of engineering and materials science, together with other elements of this architecture. The research was part-funded beneath the US Defense Advanced Research Projects Agency’s Vanishing Programmable Resources program.
