'Wearable microgrid' uses the human body to sustainably power small gadgets

This shirt harvests and stores energy from the human body to power small electronics. UC San Diego nanoengineers call it a "wearable microgrid"—it combines energy from the wearer's sweat and movement to provide renewable power for wearable devices. Full Story

Weakness is strength for this low-temperature battery

Nanoengineers at the University of California San Diego have discovered new fundamental insights for developing lithium metal batteries that perform well at ultra-low temperatures; mainly, that the weaker the electrolyte holds on to lithium ions, the better. By using such a weakly binding electrolyte, the researchers developed a lithium metal battery that can be repeatedly recharged at temperatures as low as -60 degrees Celsius—a first in the field.

New material is next step toward stable high-voltage long-life solid-state sodium-ion batteries

A team of researchers designed and manufactured a new sodium-ion conductor for solid-state sodium-ion batteries that is stable when incorporated into higher-voltage oxide cathodes. This new solid electrolyte could dramatically improve the efficiency and lifespan of this class of batteries. A proof of concept battery built with the new material lasted over 1000 cycles while retaining 89.3% of its capacity--a performance unmatched by other solid-state sodium batteries to date.    Full Story

New skin patch brings us closer to wearable, all-in-one health monitor

UC San Diego engineers have developed a soft, stretchy skin patch that can be worn on the neck to continuously track blood pressure and heart rate while measuring the wearer’s levels of glucose as well as lactate, alcohol or caffeine. It performs as well as commercial monitoring devices such as a blood pressure cuff, blood lactate meter, glucometer and breathalyzer.  Full Story
