University of California San Diego (UCSD) researchers developed an electronic patch that can monitor biomolecules in deep tissues.

The technology can monitor hemoglobin, providing medical professionals with access to crucial information for spotting life-threatening conditions. This includes malignant tumors, organ dysfunction, cerebral or gut hemorrhages and more.

Researchers published a paper on the developments in the December 15, 2022 issue of Nature Communications.

“The amount and location of hemoglobin in the body provide critical information about blood perfusion or accumulation in specific locations,” said Sheng Xu, professor of nanoengineering at UC San Diego and corresponding author of the study. ̶…

New semiconductor design boosts AI computing efficiency

Medical devices could one day get a boost from a new energy-efficient semiconductor designed with AI computing in mind.

Stanford engineers have developed a new resistive random-access memory (RRAM) chip called NeuRRAM that does AI processing within the chip’s memory, saving the battery power traditionally spent moving data between the processor and storage.

“The data movement issue is similar to spending eight hours in commute for a two-hour workday,” Weier Wan, a recent graduate at Stanford leading this project, said in a news release. “With our chip, we are showing a technology to tackle this challenge.”

They say their compute-in-memory (CIM) chip is about the size of a fingertip and does more work with limited battery power than current chips. That makes the new chip a potential space-saver for medical de…

This steerable catheter for the brain could improve aneurysm treatment

[Image courtesy UC San Diego researchers]Researchers at the University of California in San Diego have developed a way to make steerable catheters that can precisely navigate the brain vasculature.

The team of researchers designed the device to navigate the brain’s arteries and blood vessels to treat aneurysms and other neurological conditions. It was inspired by insect legs and flagella tail-like structures that allow microscopic organisms to swim, according to the researchers.

So far, the steerable catheter has been successfully tested in pigs at the Center for Future of Surgery at UC San Diego.
