Pillars for chiplet integration Researchers from the Tokyo Institute of Technology proposed a new chiplet integration technology called Pillar-Suspended Bridge (PSB), which they say is a simpler method of chip-to-chip connection compared to silicon interposers and redistribution layers. In the PSB, only a pillar-shaped metal structure called a "MicroPillar" is interposed at the connection b... » read more

Disposable water-activated battery Researchers at Empa developed a water-activated disposable paper battery that could be used in low-power, single-use disposable electronics such as smart labels for tracking objects, environmental sensors, and medical diagnostic devices. The battery is made of at least one cell measuring one centimeter squared and consisting of three inks printed onto a re... » read more

Optical oscilloscope Researchers from the University of Central Florida developed an optical oscilloscope to measure the electric field of light. The high speed at which light oscillates has made reading its electric field challenging, with current instruments able to resolve an average signal associated with a pulse of light rather than individual peaks and valleys within the pulse. “... » read more

Backscatter radios for 5G Researchers at the Georgia Institute of Technology, Nokia Bell Labs, and Heriot-Watt University propose using backscatter radios to support high-throughput communication and 5G-speed Gb/sec data transfer using only a single transistor. “Our breakthrough is being able to communicate over 5G/millimeter-wave (mmWave) frequencies without actually having a full mmWave... » read more

Direct solar energy storage Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes wate... » read more
