If you toss and turn at night, a host of gadgets are eager to help you get some quality shut eye. As with health-tracking technology, it's ultimately up to you to be proactive and fix the issues that keep you up. Sleep monitors collect a wealth of information when you snooze — brain waves, motion, heartbeat, breathing, etc. — and ideally provide an online component that compiles this data into beautiful charts to help you understand your habits over time. While informative, sleep analytics can't tell the whole story. Instead, it's up to the sleeper to fill in the gaps. To fully take advantage of these technologies, it's recommended that you log additional information in sleep journals (often provided by apps or Web dashboards), noting how you felt upon waking and chronicling factors that might have contributed to poor sleep, such as alcohol, coffee, temperature, bright lights, big meals, etc. This can help you see correlations between lifestyle/environment and body. Of course, not all sleep gadgets were made equal. Let's take a look at nine popular ones on the market and what they offer.
DARPA-sponsored research projects are usually pretty crazy, and so is this one: a group of researchers have created electronic systems that can totally dissolve in liquid after they're no longer needed, even inside the human body.
For things in your head that are designed to eat stuff, eating stuff seems to be kind of a big deal for teeth. They're always demanding to be brushed and flossed and rinsed and taken to the dentist and whatnot. Japan is having none of this, and scientists there have created tooth armor that can keep you from getting any more cavities.
Being color blind really sucks, and in some situations it can even be dangerous, especially if you forget which end of the traffic light is supposed to be red. These glasses are designed to fix the problem, with special filters that enhance some colors while filtering out others.
The days of electronic circuitry with stiff circuit boards are a thing of the past; stretchable electronics are taking over. We already saw microelectronics used in sutures to monitor for infection, and now stretchable skin with microelectronics for monitoring health conditions is readying for a debut.
Soon the days of large, battery-powered implants like a pacemaker may be a thing of the past. A team of engineers at Stanford has delivered a proof-of-concept device that was small enough to propel itself through the blood stream, demonstrating the ability to power micro-devices wirelessly.
So, we just went through this issue with the Fliz concept bicycle. Why not just run or cycle and call it a day? In this case, as the instructional video for the Treadmill Bike indicates: some people just want to take their favorite gym workout outside.
In these days of artisinal cheeses, environmentally-friendly yoga mats, and mainstream TV shows like Weeds, cannabis smoking has, for some, become yet another symbol of a healthy lifestyle. But according to a new study, the substance could impact your chances of becoming the next Einstein.
The Army is fighting a war within its own ranks as suicide rates have reached the highest in Army history. The Pentagon reports suicide within Army ranks have averaged one per day this year, which surpasses combat fatalities. A nasal spray (similar but more medicinal than this one) could change this.
Every time you think the magic of what smartphones can do has peaked, something else comes along to raise the bar. This time the magic crosses the threshold between tech and biology by giving you a way to check your health just by staring at your smartphone.
