Take a vacation from smoking: Trying to kick the habit? Don't leave home without Smokio, the vape pen that calculates how much money you're saving compared with what you'd spend on cigarettes—cash that will come in handy on your next trip. (us.smokio.com, $80)
Share your snaps anywhere: Zip is a mobile printer that syncs with your phone or tablet and spits out peel-and-stick Polaroids, so you can lift your selfie game to new levels. (polaroid.com, $130)
A gym shirt that collects more than sweat: Flying to see clients needn't be an excuse to slack off at the gym. Wear Athos as or underneath your exercise gear; snap in the Core device, and it'll collect data (heart and breathing rates, etc.), letting you chart your progress on its app. (liveathos.com, $99 plus $199 for the Core)
A game way to work out in your hotel: If you're stiff after a flight, attach the Valedo's sensors to your chest and lower back—they'll direct an avatar on your iPad, Wii-style, as it wends its way through obstacle courses. You'll stretch sore muscles without it feeling like exercise. (valedotherapy.com, $359)
Protect your posture: Miss your standing desk? Pin Lumo Lift to your chest, and it'll vibrate when you start slipping down your seat at the next all-day off-site. (lumobodytech.com, $80)

Sleep soundly wherever you go: Noise-canceling headphones do only so much. SleepPhones slip over your eyes to block light and let you nod off to tunes on your side, which even earbuds don't. (sleepphones.com, $40)
Bring your own pedal: Connected Cycle, a clip-in replacement pedal (still in development), is for those who want to log routes, speeds, and calories burned—not just spin their wheels in a hotel gym. (connectedcycle.com)
A homing beacon for your bags: Drop Trakdot into your checked luggage, and if the airline mistakenly sends it to Boston, not Austin, at least you'll know where it is. (trakdot.com, $50)
The little laptop charger that could: Traveling light? Dart is a quarter of the size of a typical power bar, guaranteeing that you'll save space in your carry-on. (finsix.com, $89)

It also locks from your phone, tells you where it is, and comes with a built-in battery to charge devices en route. Now if only it could fold a shirt. (bluesmart.com, $339)
