A smartphone’s camera and flash could help people measure blood oxygen levels at home

Conditions like asthma or COVID-19 make it harder for bodies to absorb oxygen from the lungs. In a proof-of-principle study, University of Washington and University of California San Diego researchers have shown that smartphones are capable of detecting blood oxygen saturation levels down to 70%. This is the lowest value that pulse oximeters should be able to measure, as recommended by the U.S. Food and Drug Administration.

Decoding birds’ brain signals into syllables of song

Researchers can predict what syllables a bird will sing—and when it will sing them—by reading electrical signals in its brain, reports a new study from the University of California San Diego. The work is an early step toward building vocal prostheses for humans who have lost the ability to speak.

New upgrades to old wireless tech could enable real-time 3D motion capture

A wireless technology that is helping people find their keys and wallets could one day be used for precise and real-time 3D motion capture, thanks to upgrades developed by electrical engineers at the University of California San Diego. The team’s new work improves on ultra-wideband (UWB) wireless technology so that it is faster, extremely low power and able to provide high accuracy in 3D localization.

Researchers Develop Novel Analog Processor for High Performance Computing

Analog photonic solutions offer unique opportunities to address complex computational tasks with unprecedented performance in terms of energy dissipation and speeds, overcoming current limitations of modern computing architectures based on electron flows and digital approaches.  In a new study published…

This technology could bring the fastest version of 5G to your home and workplace

A new technology developed by electrical engineers at UC San Diego might one day allow more people to have access to 5G connectivity that provides ultra-fast download speeds along with widespread, reliable coverage—all at the same time. The technology enables millimeter wave signals to overcome blockages while providing high throughput.

Neural implant monitors multiple brain areas at once, provides new neuroscience insights

How do different parts of the brain communicate with each other during learning and memory formation? A study by researchers at UC San Diego takes a first step at answering this fundamental neuroscience question, thanks to a neural implant that monitors multiple brain regions at the same time.

Upgraded radar can enable self-driving cars to see clearly no matter the weather

A new kind of radar could make it possible for self-driving cars to navigate safely in bad weather. Electrical engineers at the University of California San Diego developed a clever way to improve the imaging capability of existing radar sensors so that they accurately predict the shape and size of objects in the scene. The system worked well when tested at night and in foggy conditions.

Breaking the Size and Speed Limit of Modulators: The Workhorses of the Internet

SUMMARYResearchers developed and demonstrated for the first time a silicon-based electro-optical modulator that is smaller, as fast as and more efficient than state-of-the-art technologies. By adding indium tin oxide (ITO) – a transparent conductive oxide found in touchscreen displays and…

Continuous soil fertility monitor could benefit agriculture

The ever-increasing price of fertilizers and environmental concerns about nutrient runoff make development of a rugged continuous electronic monitoring device to detect soil fertility a possible boon to agriculture in the United States and the United Kingdom (UK).
