Bio degradable electronics
As electronics become increasingly pervasive in our lives – from smart phones to wearable sensors – so too does the ever rising amount of electronic waste they create. A United Nations Environment Program report found that almost 50 million tons of electronic waste got thrown out in 2017—more than 20 percent higher than waste in 2015. Troubled by this mounting waste, Stanford University engineer Zhenan Bao and her team are rethinking electronics. The team created a flexible electronic device that can easily degrade just by adding a weak acid like vinegar. The results were published May 1 in Proceedings of the National Academy of Sciences.
