Water is one of the main sustainability challenges for making semiconductors--which go into everything from computer processors to video games and cars. One reason making semiconductors requires so much water is that the chips have to be extensively cleaned. Engineers at the University of Arizona have developed a real-time sensor to tell when chips are clean, which means less water wasted.

Engineers at the National Institute of Standards and Technology have developed a flexible memory chip, able to be bent or twisted while still functioning. One benefit could be in the area of health: flexible chips could serve as wearable sensors to track blood pressure or heart rate.
