The world is full of non-biodegradable waste. Devices nowadays were short-lived people changes gadgets from time to time. Sure devices and gadgets were built with a composition of different components and some of these components after the device life ends turned into waste. Some can be recycled and some are to sit forever in this world.
Manufacturing of devices will not end from here, not now, but despite the current trend of manufacturing devices and the composition that built it, researchers on the other hand were also unstoppable.
For instance, researchers at the University of Illinois have develop a new type of transitory electronic device which can destruct itself once it is exposed with heat, they have widened their research after the previous study which involves electronic devices that dissolve in water when time comes that the devices becomes no longer useful.
Certainly the aim of this particular study is to make the materials from devices which also populated the world, will be dissolved completely and do not necessarily end up below earth’s ground which never decays, once it reaches the end of its useful days.
The recent work is composed of a group of researchers led by Scott R. White an aerospace engineering professor in collaboration with John A. Rogers, who previously led work in the development of transient electronics that biodegrade in water. While the previous work to biodegrade the devices in water takes ample amount of time the new work to biodegrade electronic devices using heat can self-destruct it when needed.
HOW DOES THIS TECHNOLOGY WORKS?
It is associated with printing magnesium circuits on thin and flexible materials at first then weak acid – a microscopic droplets will then be trapped in wax that is coated on the devices. The wax melts and releases acid when it is exposed to heat, the acid will completely dissolve the device.
“We have demonstrated electronics that are there when you need them and gone when you don’t need them anymore,” says White. “This is a way of creating sustainability in the materials that are used in modern-day electronics. This was our first attempt to use an environmental stimulus to trigger destruction.”
White also added that “If you can’t keep using something, whether it’s obsolete or just doesn’t work anymore, we’d like to be able to bring it back to the building blocks of the material so you can recycle them when you’re done, or if you can’t recycle it, have it dissolve away and not sit around in landfills,” says White.
