Cheap, Flexible, Battery-Free Tags to Control Your IoT Devices

Tuesday, September 11, 2018

The Internet of Things is a bit of a double-edged sword. On the one hand, outfitting your home with IoT devices can make a lot of tasks more convenient. But, on the other hand, IoT devices get expensive quickly when every device and control needs a microcontroller and WiFi capability. These new smart tags could, potentially, reduce that cost dramatically by providing control with simple, incredibly inexpensive, printable circuits.

Smart Tags Add Touch Controls to Ordinary Objects

Monday, August 27, 2018

Despite the modern world's fixation with touchscreen smartphones and tablets, most homes and businesses remain cluttered with objects that lack any digital interfaces. Now, those ordinary objects could get an upgrade thanks to new smart tags that harness reflected Wi-Fi signals to add touch-based controls to any surface. The new LiveTag technology allows for interactive controls or keypads that can stick onto objects, walls, or even clothing, and let people remotely operate music players or receive hydration reminders based on the amount of liquid remaining in a water bottle.

These Tags Convert Just About Anything Into a Smart Device

Monday, August 20, 2018

The revolution of smart devices marches on as researchers have made printable tags that mirror some functionality of standard smart gadgets. While that might sound like a major leap at first, it obviously comes with some important caveats. You can't just slap these on a TV and get Hulu, but they do allow you to use them for some basic home programming. The tags work by reflecting WiFi signals to a device that's configured to look for them. By slapping the reflectors on whatever, you can turn them and your phone into a WiFi radar system.

LiveTag is out to make dumb objects smart

Thursday, August 16, 2018

"Smart" internet-connected devices could indeed make life easier for us, but the things do typically have to be equipped with battery-powered electronics. That may not necessarily be the case for much longer, however, if the Wi-Fi-based LiveTag system reaches fruition. Developed by a team at the University of California San Diego, the system incorporates simple low-cost tags that can be adhered to everyday non-electronic objects. Those tags consist of patterns of copper foil that are printed onto a flexible paper-like substrate -- they don't have any batteries, chips or electronic components.

UC San Diego developing biosensor that monitors alcohol in people struggling with substance abuse

Tuesday, May 8, 2018

UC San Diego has made an important technical advance in its effort to develop a tiny biosensor that could be placed beneath a person's skin for long-term alcohol monitoring in patients being treated for substance abuse. A team led by engineer Drew Hall created a prototype of the sensor that worked when it was placed in a simulated environment in the laboratory. The device now has to be refined so that it can be tested in live animals and, eventually, humans.

New Injectable Alcohol Biosensor Monitors BAC

Friday, April 20, 2018

For recovering alcoholics, accountability remains one of the most elusive pitfalls of long term sobriety. It's easy to backslide into bad habits when no one is watching. But thanks to UC San Diego's Jacobs School of Engineering, there is hope on the horizon for long term sober accountability. They are developing an injectable alcohol biosensor chip that continuously monitors blood alcohol content (BAC).

Skin Sensor Might Someday Track Alcoholics' Booze Intake

Wednesday, April 18, 2018

An injectable sensor that could provide ongoing monitoring of the alcohol intake of people receiving addiction treatment is in development. The miniature biosensor would be placed just beneath the skin surface and be powered wirelessly by a wearable device, such as a smartwatch or patch, the University of California, San Diego engineers explained. "The ultimate goal of this work is to develop a routine, unobtrusive alcohol and drug monitoring device for patients in substance abuse treatment programs," project leader Drew Hall said in a university news release.

This Implantable Chip Could Monitor Alcohol Intake

Tuesday, April 17, 2018

People arrested for DUIs or other alcohol-related offenses are sometimes ordered to wear so-called SCRAM (secure continuous remote alcohol monitoring) bracelets. The device, usually worn on the ankle, can detect alcohol consumption through the skin. Patients in rehab programs often submit to alcohol monitoring as well, often through Breathalyzers or blood tests. But SCRAM bracelets are clunky and sometimes embarrassing, and tests require regular visits. A team of scientists from UC San Diego has come up with a potential alternative: a tiny implantable chip.

Injectable chip measures alcohol consumption

Wednesday, April 11, 2018

There may be a new -- if perhaps somewhat Big Brother-like -- method of monitoring the alcohol intake of people in substance abuse treatment programs. Led by Prof. Drew Hall, scientists at the University of California San Diego have developed an alcohol-sensing chip that can be implanted in the body. The chip is designed to be injected under the skin, where it will sit in the interstitial fluid that surrounds the cells. The chip uses very little power (which it draws from the watch's RF signals) and takes just three seconds to conduct one measurement.

The next breathalyzer may be a chip implanted under your skin

Wednesday, April 11, 2018

A group of engineers at the University of California, San Diego, created a prototype of a chip, meant to be injected under the skin, that could eventually be helpful for people who are in treatment for alcohol abuse. At just one millimeter across, it's a fraction the size of a penny, which means it would be a lot less bulky than current alcohol-monitoring bracelets. Researchers say it can be more accurate than a breathalyzer test, and it's less invasive than a blood test.

Chaos could provide the key to enhanced wireless communications

Tuesday, August 16, 2016

Chaos, somewhat ironically, has one clear attribute: random-like, apparently unpredictable, behavior. However recent work shows that that unpredictable behavior could provide the key to effective and efficient wireless communications.

The combination of products with “built-in smart technology” with consumers’ expectations of a “best-in-class experience” means mundane, manually performed tasks will be replaced by new “exciting and indispensable services,” says Accenture innovation division Fjord in two reports. Fjord reckons we’re on the cusp of a new way of doing things. That includes the fact that user requirements will be addressed dynamically, contextually, and in real-time—more so than ever before.

The show floor at the annual Consumer Electronics Show in Las Vegas is packed with all sorts of flashy new consumer devices that are meant to grab people’s attention, but one of the biggest announcements from this year’s show isn’t an HDTV, a drone or a hoverboard. It’s also not a “smart” device, which will again be the focus of CES this year as we push closer toward a time when “Internet of Things” gadgets proliferate and infiltrate every corner of our homes and offices.
