Researchers from Aalto University in Finland have published a paper giving simulations of the communications via digitally controlled antenna arrays and claim this could provide a boon to mobile communications. It would do this by replacing multiple frequency-specific antennas for GPS, Bluetooth and Wi-Fi and so on with a single antenna system that can support high bandwidths more efficiently. Such antennas would also make numerous analog components used to tune traditional antennas to the desired frequency obsolete. "The next step in the development process is under way with the commencement of tests in cooperation with Huawei using fifth generation mobile phone devices," said Professor of Radio Engineering Ville Viikari, in a statement. "We are also developing together with Aalto University researchers digital electronic systems for controlling the antennas."

Researchers from the Korea Advanced Institute of Science and Technology (KAIST) have developed ultrathin, transparent oxide thin-film transistors that could address wearable displays. Published in the journal of Advanced Functional Materials, their findings "Skin-Like Oxide Thin-Film Transistors for Transparent Displays" relate to the fabrication of ultrathin and transparent oxide thin-film transistors (TFT) using the inorganic-based laser lift-off (ILLO) method they had already successfully developed for energy-harvesting and flexible memory devices.
