The tattoo biosensor for monitoring lactate levels that has been converted into a sweat-po...

Last year, researchers at the University of California, San Diego (UCSD) unveiled a sensor imprinted on a temporary tattoo that, when applied to the skin, is able to continuously monitor lactate levels in a person's sweat as they exercise. Now the research team has leveraged the technology to create a biobattery powered by perspiration that could lead to small electronic devices being powered by sweat.  Read More

There's gold in that thar belly – or at least there might soon be, if a new form of liposu...

Liposuction may be a popular method of instant body fat reduction, but it certainly isn't perfect. Patients can experience bruising, there can be lumps that have to be addressed with a second procedure, plus things other than fat cells – such as connective tissue and nerves – can inadvertently also get removed. Two researchers, however, are developing what could be a better form of liposuction, that involves first using injected gold microparticles to melt the fat.  Read More

It can be hard enough for parents to maintain a cool head when dealing with an angry child at the best of times, but things can get much more difficult when that child has ADHD (attention deficit hyperactivity disorder). That's why scientists at Microsoft Research and the University of California, San Diego have created ParentGuardian. It combines a wrist-worn sensor and an app, to monitor parents' stress levels and deliver real-time coping strategies.  Read More

MiP balances on two wheels, using the mobile inverted pendulum principle

You may never be able to afford your own Segway, but soon you'll be able to buy something similar for just a hundred bucks. You won't be able to ride it, but it might ultimately end up being more fun. It's Wowwee's MiP toy robot, which performs a variety of activities while balancing on its two wheels.  Read More

Bioinspired magnetically propelled helical microswimmers could deliver drugs at the right ...

If you remember the 1966 science fiction film Fantastic Voyage, you'll recall how miniaturized government agents traveled through blood vessels in a tiny submarine, in their attempt remove a blood clot from a scientist's brain. Synthetic nanomotors that can do the same job have been the subject of numerous research efforts and now University of California, San Diego (UCSD) researchers report that they've created powerful biodegradable "microswimmers" that can deliver drugs more precisely, derived from common plants like passion fruit and wild banana.  Read More

USCD Jacobs researchers have developed an algorithm that uses computer vision to identify ...

Whether it's fashion, a favorite football team, or a certain kind of music, humans seem to enjoy being considered part of a larger group, and often self-identify as such. With this in mind, students from the UCSD (University of California, San Diego) Jacobs school of Engineering are currently developing a computer algorithm that can deduce from an image whether you're a goth, surfer, hipster, or biker.  Read More

Computer scientists have come up with a new simple, accurate way to simulate the appearance of fabric that could change the way artists and animators in the film and computer game industries go about the business of rendering computer-generated clothing and other materials.  Read More

The lactate-monitoring biosensor tattoo on one of the test subjects

No athlete likes hitting “the wall.” You know, that point at which their energy level suddenly plummets, and they just can’t go on. Using something that looks like a temporary tattoo, however, they may soon be able to receive a warning when they’re approaching that threshold.  Read More

A child playing as seen by a person with Age-related Macular Degeneration

Age-related macular degeneration (AMD) is the leading cause of blindness among older adults in the western world. Unfortunately, conventional optical aids provide little help for a retina which has lost the acuity of its central area. Now a team of multinational researchers led by University of California, San Diego (UCSD) Professor Joseph Ford has created a telescopic contact lens that can switch between normal and magnified vision to offer AMD patients a relatively unobtrusive way to enhance their vision.  Read More

The SkySweeper robot that inches along a cable using a motorized pivoting 'elbow'

If you look up at a power line in a few years and see something skittering along the wires, it (hopefully) won't be a mutant crab monster, but a powerline inspection robot costing less than US$1,000. A prototype of such a robot, called SkySweeper, was presented this month at the University of California San Diego (UCSD) Jacobs School of Engineering's Research Expo. The robot was built with off-the-shelf electronics and plastic parts printed on an inexpensive 3D printer.  Read More
