While there is much being published about the continual shrinking of electronics, there are a number of other activities that have been developing. One of the efforts is directed at reducing the amount of discarded electronics that end up in landfills. This becomes especially important as the Internet of Things (IoT) creates numerous wearable (and discardable) devices.<\/p>\n
One of the ways this can be done is to create environmentally friendly electronics. A team of researchers at the University of Wisconsin Madison has worked with the U.S. Department of Agriculture to create semiconductor chips made almost entirely out of wood! [Ref. 1] Their contention is that the majority of the semiconductor material is employed to provide a structure to hold the actual electronics. They created a cellulose nanofibril for the foundation of the electronics. More details are available in the referenced web publication.<\/p>\n
Another approach to reducing the amount of waste is to have the electronics self-destruct. Researchers at the University of Illinois have developed het triggered self-destruction electronic devices. The indication is that they could also create a RF controlled trigger to initiate the process. \u201cThe heat-triggered devices use magnesium circuits printed on very thin, flexible materials. The researchers trap microscopic droplets of a weak acid in wax, and coat the devices with the wax. When the devices are heated, the wax melts, releasing the acid. The acid dissolves the device quickly and completely\u201d [Ref. 2]<\/p>\n
Researchers in China have created a light-emitting, transparent and flexible paper. \u201cThe researchers developed a thin, clear nanocellulose paper made out of wood flour and infused it with biocompatible quantum dots\u2014tiny, semiconducting crystals\u2014made out of zinc and selenium. The paper glowed at room temperature and could be rolled and unrolled without cracking.\u201d [Ref. 3]<\/p>\n
As a side note, it is interesting how science fiction can find its way into reality. While it is too early to indicate success, researchers have found a phenomena that \u201coccurs when injecting tiny grains of Lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically. High heat and pressure are crucial to fusion.\u201d [Ref. 4] Have we taken another step toward fusion power generation? Star Trek Di-lithium crystals anyone?<\/p>\n
