Capturing waste heat Researchers at Wuhan University and University of California Los Angeles developed a hydrogel that can both cool down electronics and convert the waste heat into electricity. The thermogalvanic hydrogel consists of a polyacrylamide framework infused with water and specific ions. When they heated the hydrogel, two of the ions (ferricyanide and ferrocyanide) transferred e... » read more

Conflicting Demands At The Edge

Semiconductor Engineering sat down to define what the edge will look like with Jeff DeAngelis, managing director of the Industrial and Healthcare Business Unit at Maxim Integrated; Norman Chang, chief technologist at Ansys; Andrew Grant, senior director of artificial intelligence at Imagination Technologies; Thomas Ensergueix, senior director of the automotive and IoT line of business at Arm; V... » read more

Auto Power Becoming Much More Complex
By Bryon Moyer - 14 May, 2020 - Comments: 0

Rising electronics content in automobiles is putting increased focus on automotive power delivery networks (PDNs). Safety implications mean that thorough power design and verification, along with novel power isolation techniques, are needed at the vehicle level, involving both electrical and mechanical considerations. The electronic takeover can be measured by the percentage that electronic ... » read more

CMOS-compatible laser Researchers at Forschungszentrum Jülich, Center for Nanoscience and Nanotechnology (C2N), STMicroelectronics, and CEA-Leti Grenoble developed a CMOS-compatible laser for optical data transfer. Comprised of germanium and tin, the efficiency is comparable with conventional GaAs semiconductor lasers on Si. Optical communications provide much higher data rates, and are be... » read more

Flat microwave reflector Researchers from Los Alamos National Laboratory developed a new flat reflector for microwaves that could improve communications while providing a better form factor. It also breaks reciprocity, effectively turning it into a one-way mirror. The flat reflector can be reconfigured on the fly electronically, allowing it to be used for beam steering, customized focusing,... » read more

MRAM speed Researchers at ETH Zurich and Imec investigated exactly how quickly magnetoresistive RAM (MRAM) can store data. In the team's MRAM, electrons with opposite spin directions are spatially separated by the spin-orbit interaction, creating an effective magnetic field that can be used to invert the direction of magnetization of a tiny metal dot. "We know from earlier experiments, i... » read more

Healing perovskites Researchers at Brown University found that while perovskite solar cells can crack easily, they are also capable of healing those cracks. "The efficiency of perovskite solar cells has grown very quickly and now rivals silicon in laboratory cells," said Nitin Padture, a professor in Brown's School of Engineering and director of Brown's Institute for Molecular and Nanoscale... » read more

Power/Performance Bits: Dec. 9

Solar capture and storage Researchers at the University of Houston developed a device capable of both capturing and storing solar energy. Unlike solar panels and solar cells, which rely on photovoltaic technology for the direct generation of electricity, the hybrid device captures heat from the sun and stores it as thermal energy. The device combines molecular energy storage and latent heat... » read more

Planning For Panel-Level Fan-out
By Mark LaPedus - 21 Nov, 2019 - Comments: 0

Several companies are developing or ramping up panel-level fan-out packaging as a way to reduce the cost of advanced packaging. Wafer-level fan-out is one of several advanced packaging types where a package can incorporate dies, MEMS and passives in an IC package. This approach has been in production for years, and is produced in a round wafer format in 200mm or 300mm wafer sizes. Fan-out... » read more

Flexible battery Researchers at ETH Zurich developed a flexible thin-film battery that can be bent, stretched, and twisted without interrupting the supply of power. Key to the battery is a new electrolyte and entirely flexible components. "To date, no one has employed exclusively flexible components as systematically as we have in creating a lithium-ion battery," said Markus Niederberger, P... » read more
