Transient Technologies: Dissolvable and Eco-Friendly Electronics
Planned obsolescence has caused an enormous amount of damage to our environment around the world.
From plastics floating "islands" in our seas, to mountains of discarded computers and cell phones. E-waste has become a huge 21st-century issue and it will only continue if we do not do something to stop it.
Researchers at the University of Illinois in collaboration with Tufts University and Northwestern University have created new dissolvable eco-friendly "Transient Technologies." Soon, your old old cell phones, computers, digital cameras and other technologies could be dissolve and absorbed back into the environment simply by adding water.
John A. Rogers, the Lee J. Flory-Founder Professor of Engineering at the U. of I., who led the multidisciplinary research team. calls this 'Transients Technology.' “From the earliest days of the electronics industry, a key design goal has been to build devices that last forever – with completely stable performance. But if you think about the opposite possibility – devices that are engineered to physically disappear in a controlled and programmed manner – then other, completely different kinds of application opportunities open up.”
Environmentalists and futurists will only be satisfied if these transient technologies are completely biocompatible and capable of absolute absorption back into the environment or in body fluids. Rogers' group has been able to develop small yet high performance electronic systems on ultra thin sheets of silicone that completely dissolve in several days once submerged in biofluids. Transient Technologies utilizes soluble conductors and dielectrics using a magnesium and magnesium oxide substrate. The substrate can provide a wide range of electronic components wireless transmission systems and sensors.
The team has experimented with transistors, diodes photodetectors, solar cells and even a simple digital camera. These components can take minutes, days, weeks, or even years to dissolve and are encapsulated in silk which determines its rate of dissolution.
If these technologies turn out to be completely safe and biocompatible this could change the way we interact with technology. The guilt of buying a new phone every year will disappear and yet at the same time corporations may tighten the grip of their already absurd planned obsolescence mantra. This could cause a rise in production and an increase in the cost of owning and maintaining transient technologies. Could we see the rise of a new iPhone every month? Could 3-D printers start using transient technologies substrate as a printing material? Corporations and environmentalists will need to monitor the progress of transient technologies to ensure they are utilized in the most effective and productive way. At Serious Wonder we see transient technologies as a way of cleaning our environment and leaving a smaller footprint.
What do you think? Are transient technologies a good idea?

Star Trek Into Darkness: Eye candy for the amygdala. Yes, this is another Hollywood blockbuster depicting a dystopian future with big explosions and small innovations. However, the first ten minutes are worth the price of the ticket. I was pleasantly surprised to see J.J. Abrams using the Ancient Aliens theory and a huge wink to author Zecharia Sitchin's work in the opening scene located on the fictional (depending on who you ask) world of Nibiru.
Spray-on skin. Lab-grown ears. Human tissue grown in a petri dish. We're going deep into sci-fi territory (and it is already happening).
“Extropy” is celebrating its first quarter of a century. The idea was formally introduced as a philosophy of the future in 1988, and many things have happened from the end of the 20th century to the beginning of the 21st century. A new millennium has been born and the philosophy of extropy is well-suited for these new times of accelerating change, full of challenges and opportunities.
One definition of resilience is “the ability to cope with shocks and keep functioning in a satisfying way”. Resilience is about the self organizing capacity of systems. This means the ability to bounce back after disaster, or the ability to transform if a bad stage has happened.
This is my last posting for the next few days. I will be taking my office apart so that we can move to our new apartment downtown next Tuesday. I will be unplugged and disconnected except by tablet. Expect me to be back in the saddle before the end of next week probably in time to provide you with some more headlines. In the interim these are the stories I share with you this week:
Today, literally thousands of alternative transportation vehicles are coming out of the woodwork and they nearly all have the same problem – no place to drive them. Most are banned from biking and hiking trails, and they are neither licensed, nor licensable, for use on the streets. I’d like to discuss some new possible solutions and why Colorado is poised to take the lead in the alternative transportation marketplace.
In a recent conference promoting not only their latest gizmos but their company's animating vision as well, Google executives declared they were working toward a future in which technology "disappears," "fades into the background," becomes more "intuitive and anticipatory." Commenting on this apparently "bizarre mission for a tech company," Bianca Bosker warns that their genial and enthusiastic promotional language masks Google's aspiration to omnipresence via invisibility, an effort to render us dependent and uncritical of their prevalence through its marketing as easy, intuitive, companionable.
