Nature Electronics

We are constantly surrounded by electromagnetic waves such as Wi-Fi. Researchers at Tohoku University tested a device to convert this ambient energy into energy for electronic devices.

A research team co-led by a scientist at City University of Hong Kong (CityU) has developed a novel antenna that allows manipulation of the direction, frequency and amplitude of the radiated beam, and is expected to play an important role in the integration of sensing and communications (ISAC) for 6th-generation (6G) wireless communications.

Researchers have established a low-cost method of magnetization reversal on perpendicularly magnetized ferromagnets. Not needing an external magnetic field, the method brings reverse magnetization closer to commercial viability.

A research team, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has succeeded in patterning the two-dimensional (2D) metal electrode into desired shapes on the 4-inch diameter silicon substrate.
