Magnetic levitation (Maglev) is well known for its use in high-speed rail networks, but could also be applied at smaller scales in medicine and electronics. To do so, researchers must be able to precisely control electromagnetic fields so that they can move and rotate objects without touching them. Now, Teo Tat Joo and co-workers at…

Roll-to-roll printing a conductive metal ink offers an inexpensive, high performance alternative to today’s touchscreen technology. A touchscreen is an essential feature of many modern devices, but the material that gives most screens their touch sensitivity is in short supply. By adapting newspaper printing technology, researchers at Agency for Science, Technology and Research (A*STAR), Singapore,…

Calculations reveal how sensors must take turns to harvest power efficiently from a data hub. Algorithms that describe the most efficient ways to transmit data and power between wireless sensors and a central hub could help develop large networks of smart devices. Interconnected wireless devices are increasingly common. For example, smart home appliances can transmit…
