Check out five tech innovations that just might save your life

Anyone who has ever had his cell phone ring in a crowded movie theater or walked into a street lamp while texting knows that technology doesn’t always have your back. It doesn’t have to be that way – meet five new technical innovations that might just save your life.

Lending a Hand

Biking can be a daunting, and dangerous, feat for anyone living in a city with heavy traffic and bad drivers. That’s why Zach Vorhies and Murat Ozkan created Zackees, the first pair of LED-light embedded, washable bike gloves that signal to drivers when a biker is about to make a turn. After killing it on Kickstarter – more than doubling their $35,000 goal – the Zackees are now available for preorder.

Cutting Corners

A new surgical scalpel, dubbed rather menacingly the iKnife, can actually detect cancer mid-surgery. The knife analyzes molecules released from electrosurgical cutting and determines the tissue type. The iKnife is not yet on the market, but it has been used in over 500 surgeries in Germany, Hungary, and London and current trials have shown extremely promising results – it detected with 100% accuracy the tissue samples of 91 patients.

Serious Support

In 2013, Breastcancer.org estimated that 232,340 cases of breast cancer incidents went undiagnosed. But what if a bra could help lower that number? Cyrcadia Health claims to have created a sports bra that can actually detect cancer by using sensors that measure minute body temperature fluctuations (which can indicate breast tissue abnormalities). The jury is still out on whether this actually works, but the company continues to run successful trials and plans to launch in the U.S. by late 2015.

Head and Shoulders

Technology company MC10 develops small, discreet wearables that address a variety of health concerns in sports and wellness. In 2008, in a partnership with Reebok, they developed the Checklight, an ultra light-weight mesh cap that measures blunt force, alerting coaches and trainers to life threatening injuries or possible concussions.

Never Alone

Wearable call buttons aren’t anything new (who among us could forget “I’ve fallen and I can’t get up“?), but the options are getting better. The Guardian Angel is a piece of jewelry intended to help women and girls feel less vulnerable – when activated, the device will send a distress call to a chosen number and track GPS coordinates.

Now go forth (and keep it safe).
