US develops biodegradable semiconductor to reduce e-waste :
US researchers have developed a flexible, organic and biodegradable semiconductor that can help to cut the mounting pile of global electronic waste, a research published said. Stanford engineer Zhenan Bao and her team created the flexible electronic device that could easily degrade just by adding a weak acid — vinegar, said the Proceedings of the National Academy of Sciences’ paper. The team developed the degradable electronic circuit and a new biodegradable substrate material for mounting electrical components, Xinhua news agency reported. Electronic components are usually made of gold. But for this device, the researchers crafted components from iron. Bao noted that iron is a very environmentally friendly product and it is nontoxic to humans.

This substrate supports electrical components, flexing and molding to rough and smooth surfaces alike. When an electronic device is no longer needed, the whole thing can biodegrade into nontoxic components “In my group, we have been trying to mimic the function of human skin to think about how to develop future electronic devices,” Bao, a professor of chemical engineering and materials science and engineering, said in a statement. “We have achieved the first two (flexible and self-healing), so the biodegradability was something we wanted to tackle.” Previous material designed by Bao’s team could bend and twist in a way that could allow it to interface with the skin or brain, but it couldn’t degrade, said the Stanford release.
