Connectivity was the name of the game at this year's Consumer Electronics Show, held last week in Las Vegas -- especially when it came to health-related products. These gadgets rose above the rest as those that might really help you keep your New Year's resolutions.

Sleep soundly

A small, lightweight band users wear on their heads during sleep, the Zeo Sleep System measures brain waves while you're in dreamland, and will sync via Bluetooth with your smart device.

Zeo's free app plots out how many hours of quality snooze time you're getting each night. Great feedback for our highly caffeinated, tech-obsessed society, it also plots out sleep quality based on behaviors you input.

How much did those three glasses of vino affect your sleep? How about that late night fast-food run, or actual run?

Zeo gives you concrete tips for improving your sleep routine based on your habits, and will even wake you up at the optimum time in your sleep cycle. The Zeo is available for a one-time purchase price of $99. (No monthly subscription required.)

Body bands

A bevy of body bands made a splash at CES this year, among them the BodyMedia Fit and the Basis Band.

BodyMedia's Fit monitoring system consists of a small electric band the user wears on his or her arm, that works in conjunction with a software interface that's available on your smartphone or online. Users input their daily calorie intake, and the device monitors calories burned.

The band uses sweat sensors, an accelerometer and skin temperature monitors to figure out how much exercise you're doing, and for how long. It compares that to your food intake to give a picture of your daily health. The accelerometer knows when you're lying on your back for hours at a time (presumably sleeping), and adds that to your fitness picture as well.

The Fit CORE is available for $149, but requires plugging in to synch your data. The new Fit LINK is Bluetooth-enabled for wireless synching, and is available for $179. Both products require a $6.95 monthly subscription to BodyMedia's online dashboard.

Similar to the BodyMedia's Fit, the Basis Band adds real-time heart rate monitoring to the mix by using a optical engine that "looks through the skin to see actual blood flow," similar to the technology used in pulse oximeters (those little things they put on your finger at the doctor's office.)

The Basis Band is also worn on the wrist rather than on the arm, and looks more like a trendy watch than a fitness monitor. The Basis is available for pre-order, shipping sometime this quarter; and will be $199. The price includes lifetime access to the cloud service and online interface -- no monthly subscription required.

Smart medical devices

Smart medical devices abounded on the expo floor this year.

The Withings Wi-fi Body Scale, a sleek device that looks like an iPhone you can step on, connects with your iPhone, or other iOS or Android-capable phone.

The scale measures your weight, lean and fat mass and calculates your BMI almost instantaneously. To keep things simple (and less depressing), the display only shows your weight -- the rest of the information floats up to the cloud, and is available on your smartphone. The free app interface also lets you invite friends, family members or your doctor to view your progress; and it will keep track of data for up to eight users.

The Withings Wi-fi Scale is available for $159, which includes lifetime access to the web and phone service. Unfortunately, just because this scale is cloud-connected, doesn't mean you're going to be any lighter.

Withings also had another smart medical device: the iPhone Blood Pressure Cuff. Wrap it around your arm and then plug this bad boy into your iPhone, iPod touch or iPad. A small compressor in the device inflates the cuff, using power from your device.

Once the reading is complete, the information is logged in a free app, and is available to send to your doctor for analysis and tracking. The cuff is available for $129 with no recurring monthly fees.

California-based iHealth Labs also brought a Wi-Fi scale and blood pressure cuff to the table; but a third product really caught our attention: the Smart GlucoMeter. As more of the connected generation starts dealing with diabetes, this high-tech tool may encourage diabetics to check their blood sugar more often.

The device is simple: Plug a pack-of-gum-sized accessory into the bottom of your Apple device, insert a test strip, prick your finger (unfortunately, they haven't been able to eliminate that step). Put a drop of blood on the strip. Within a few seconds, the device measures your blood sugar, and catalogs it for you and your doctor to track. The GlucoMeter is pending approval with the FDA, and should be available in the latter half of 2012. The price has not yet been set.

Health apps

Just as cool as some of the hardware at CES was the software. "Gamification" of health was a popular phrase on the show floor, and several companies weighed in with entries to that category. Among the coolest were ...

UnitedHealth Group's OptumizeMe is a social fitness app that lets you challenge friends and family to get healthy. The app allows users to make their own health challenges or select from a list of popular challenges. Among them: competitions to see who can walk the most steps in a day, who can be the first to run 100 miles, and who can eat their daily servings of fruits and veggies.
