UC San Diego nanoengineer named among MIT Technology Review's top innovators under 35

MIT Technology Review has named Sheng Xu, a professor of nanoengineering at the University of California San Diego, as one of this year’s top innovators under 35. Xu is being recognized for inventing a clever way to make off-the-shelf electronics stretchable. Full Story

Clinical Trial Tests Tattoo Sensor as Needleless Glucose Monitor for Diabetes Patients

A temporary tattoo for glucose monitoring developed by engineers at UC San Diego is being tested in a phase I clinical trial. The study will test the tattoo sensor’s accuracy at detecting glucose levels compared to a traditional glucometer. The clinical trial is enrolling 50 adults, ages 18 to 75, with either type 1 or 2 diabetes or diabetes due to other causes.

Tiny injectable sensor could provide unobtrusive, long-term alcohol monitoring

Engineers have developed a tiny, ultra-low power chip that could be injected just under the surface of the skin for continuous, long-term alcohol monitoring. The chip is powered wirelessly by a wearable device such as a smartwatch or patch. The goal of this work is to develop a convenient, routine monitoring device for patients in substance abuse treatment programs.  Full Story

Flexible ultrasound patch could make it easier to inspect damage in odd-shaped structures

Researchers have developed a stretchable, flexible patch that could make it easier to perform ultrasound imaging on odd-shaped structures, such as engine parts, turbines, reactor pipe elbows and railroad tracks—objects that are difficult to examine using conventional ultrasound equipment. The ultrasound patch is a versatile and more convenient tool to inspect machine and building parts for defects and damage deep below the surface. Full Story

A wearable system to monitor the stomach's activity throughout the day

A team of researchers has developed a wearable, non-invasive system to monitor electrical activity in the stomach over 24 hours—essentially an electrocardiogram but for the gastro-intestinal (GI) tract.  Applications include monitoring GI activity for patients outside of a clinical setting, which cuts down costs. Monitoring for longer periods of time also increases the likelihood of capturing abnormal events.  Researchers detail their findings in the March 22 issue of Nature’s open access journal Scientific Reports.

Engineers develop most efficient red-light-activated switch that can turn genes on and off in mammalian cells

A team of researchers has developed a light-activated switch that can turn genes on and off in mammalian cells. This is the most efficient so-called “optogenetic switch” activated by red and far-red light that has been successfully designed and tested in animal cells—and it doesn’t require the addition of light sensing molecules from outside the cells.   Full Story

Nano-ink-based sensors detect an eye blink

Through developing a graphene-nanosheet-based ink, collaborators at the University of California ? San Diego and the National Taiwan University of Science and Technology have produced flexible, wearable, ultrathin sensors. Fabricated by printing multiple layers directly onto medical tape, the printed graphene sensors can be easily affixed to skin. Due to their high strain sensitivity, deformations to the sensor caused by subject movement can allow non-invasive health monitoring. Further, through combining multiple small sensor patches to make different geometries, the sensors accurately follow hand motions and can even monitor eye-blinking and pulse. Full Story
