A research team at Osaka Metropolitan University has developed a microelectromechanical system (MEMS) piezoelectric vibration energy harvester, which is only about 2 cm in diameter with a U-shaped metal vibration amplification component. The device allows for an increase of approximately 90 times in the power generation performance from impulsive vibration. Since the power generation performance can be improved without increasing the device size, the technology is expected to generate power to drive small wearable devices from non-steady vibrations, such as walking motion.

Space missions already use electric propulsion devices, where electromagnetic fields are utilized to generate the thrust of spacecraft. One such electrodeless device, which harnesses radio frequency (rf) to generate plasma and a magnetic nozzle (MN) to channel and accelerate plasma, has shown immense promise in pushing the boundaries of space travel. But scientists have so far failed to achieve efficient conversion of the rf power to thrust energy. Now, a Tohoku University researcher has achieved a 30% conversion efficiency, the biggest rate to date.

Researchers from Osaka University have developed a way of printing edible QR codes—a kind of barcode—within cookies, meaning that the tag is embedded within the food itself. Crucially, the tag doesn’t change the flavor or outer appearance of the cookie, and can be read using a backlight while the cookie remains intact. This new method has great commercial potential for improving food safety and traceability in an environmentally friendly way.
