It’s been a good decade or so for the makers of plastic lenses. In recent years, smartphone manufactures have been adding camera modules, going from one to two to five or more. And each of those camera modules contains several plastic lenses. Over the years, these lenses have changed little, though image processing software has […]
Although its origins trace back to the 1960s and ‘70s, acoustic holography as a field has been hampered by rampant noise created by widespread reflection and scattering. (Lasers tamp this problem down somewhat for conventional optical holograms; ultrasound as yet offers no such technological quick fix.) But in a recent study published last month in IEEE Sensors Journal, a […]
It was easy for exhibitors to get lost in the virtual shuffle at CES 2021, where the digital exhibit hall simply displayed the logos of the 1900-plus exhibitors. To get any detail about a particular presenter, you had to search for their booth and click into it, wading through videos, power points, PDFs, and images to try […]
CES 2021, this year’s fully virtual consumer electronics show, kicked off on Monday with Media Day and a flurry of announcements from the largest consumer electronics manufacturers. For these companies, the center of the consumer electronics world is the television—the bigger the screen the better. People generally don’t replace their TVs as often as they […]
A few parched middle-eastern countries already rely on removing salt from seawater to satiate their thirst. Many others might have to turn to desalination as they deal with increasing populations and climate change. But the technology is still expensive and requires a lot of energy. Today’s foremost desalination method, reverse osmosis, uses membranes that block […]
Spintronics is a budding path in the quest for a future beyond CMOS. Where today’s electronics harness an electron’s charge, spintronics plays with another key property: an electron’s spin, which is its intrinsic angular momentum that points either “up” or “down.” Spintronic devices use much less power than their CMOS counterparts—and keep their data even when […]
