Drones relay RFID signals for inventory control

Radio frequency ID tags were supposed to revolutionize supply chain management. The dirt-cheap, battery-free tags, which receive power wirelessly from scanners and then broadcast identifying numbers, enable warehouse managers to log inventory much more efficiently than they could by reading box numbers and recording them manually. But the scale of modern retail operations makes even

High-precision control of printed electronics

Printed electronic transistor circuits and displays, in which the colour of individual pixels can be changed, are two of many applications of ground-breaking research at the Laboratory of Organic Electronics, Linköping University. New groundbreaking results on these topics have been published in the scientific journal Science Advances. The researchers in organic electronics have a favourite

Designing new materials from ‘small’ data

Finding new functional materials is always tricky. But searching for very specific properties among a relatively small family of known materials is even more difficult. But a team from Northwestern Engineering and Los Alamos National Laboratory found a workaround. The group developed a novel workflow combining machine learning and density functional theory calculations to create

How visual attention selects important information

Studies of visual attention discovered an interesting inconsistency in spatial property. Specifically, some studies reported broad spatial spreads around attended locations, while others reported a selection of information at the attention focus. For example — according to one study, when a person looks for a friend in a crowd, visual attention makes not only the
