Stanford Researchers Combine Processors And Memory On Multiple Hybrid Chips To Run AI On Battery-Powered Smart Devices

Smartwatches and other battery-powered electronics would be even smarter if they could run AI algorithms. But efforts to build AI-capable chips for mobile devices have so far hit a wall – the so-called “memory wall” that separates data processing and memory chips that must work together to meet the massive and continually growing computational demands imposed by AI. “Transactions between processors and memory can consume 95 percent of the energy needed to do machine learning and AI, and that severely limits battery life,” said computer scientist Subhasish Mitra, senior author of a new study published in Nature Electronics. Now, a…

Stanford Engineers Have Developed A Genetic Microlab That Can Detect COVID-19 In Minutes

Throughout the pandemic, infectious disease experts and frontline medical workers have asked for a faster, cheaper and more reliable COVID-19 test. Now, leveraging the so-called “lab on a chip” technology and the cutting-edge genetic editing technique known as CRISPR, researchers at Stanford have created a highly automated device that can identify the presence of the novel coronavirus in just a half-hour. “The microlab is a microfluidic chip just half the size of a credit card containing a complex network of channels smaller than the width of a human hair,” said the study’s senior author, Juan G. Santiago, the Charles Lee Powell…

Stanford Materials Scientists Borrow Solar Panel Tech To Create New Ultrahigh-res OLED Display

Repurposed solar panel research could be the foundation for a new ultrahigh-resolution microdisplay. The OLED display would feature brighter images with purer colors and more than 10,000 pixels per inch. By expanding on existing designs for electrodes of ultra-thin solar panels, Stanford researchers and collaborators in Korea have developed a new architecture for OLED – organic light-emitting diode – displays that could enable televisions, smartphones and virtual or augmented reality devices with resolutions of up to 10,000 pixels per inch (PPI). (For comparison, the resolutions of new smartphones are around 400 to 500 PPI.) Such high-pixel-density displays will be able…

Stanford Scientists Anticipate The Mars 2020 Rover Launch

Despite a global pandemic and some technical delays, NASA’s 2020 Mars Rover – the aptly named Perseverance – is scheduled to launch this summer (currently slated for July 30) on a groundbreaking endeavor. Traveling from Earth to Mars is best done when the planets orbit nearest one another, providing only a narrow window of opportunity (rover pun intended) between mid-July and mid-August to start the journey. Its success will be the opening salvo in an ambitious series of missions designed to bring samples of Martian crust to Earth for the first time for study. NASA’s 2020 Mars Rover – the…

Stanford Researchers Harness Satellite Imagery And AI To Help Fight Poverty In Africa

In combating poverty, like any fight, it’s good to know the locations of your targets. That’s why Stanford scholars Marshall Burke, David Lobell and Stefano Ermon have spent the past five years leading a team of researchers to home in on an efficient way to find and track impoverished zones across Africa. The powerful tool they’ve developed combines free, publicly accessible satellite imagery with artificial intelligence to estimate the level of poverty across African villages and changes in their development over time. By analyzing past and current data, the measurement tool could provide helpful information to organizations, government agencies and businesses that deliver services and…

Stanford Engineers Create Shape-Changing, Free-roaming Soft Robot

Advances in soft robotics could someday allow robots to work alongside humans, helping them lift heavy objects or carrying them out of danger. As a step toward that future, Stanford University researchers have developed a new kind of soft robot that, by borrowing features from traditional robotics, is safe while still retaining the ability to move and change shape. “A significant limitation of most soft robots is that they have to be attached to a bulky air compressor or plugged into a wall, which prevents them from moving,” said Nathan Usevitch, a graduate student in mechanical engineering at Stanford. “So,…
