Women can receive fitness metrics and workout tips from sportswear startup OMsignal's smart bra, which was launched at the CES technology fair in Las Vegas this week (+ slideshow).
The brand, which launched a line of smart shirts for men in 2014, collaborated with scientists, engineers and sports bra designers to create the OMbra.

"The evolution and growth of the OMbra came to fruition through exhaustive scientific research, ensuring that only the most sophisticated and premium of sports bras was built," said the company.
"A great deal of our research was focused on biomechanics (the study of the mechanical aspects of human exercise) and support," it added.
OMsignal's OMrun platform is integrated into the bra, which measures and reports back on fitness metrics such as distance, heart rate and calories. The garment connects to a smartphone app that gives instant feedback to the user, allowing them to measure the effects of their training and workouts.
The app also gives breathing guidance to help wearers' improve their rhythm, and allows them to compare their fitness levels to their age group.
A gauge also measures cumulative fatigue, by assessing the wearer's state of rest before, during and after a workout using heart rate (HR), heart rate variability (HRV) and breathing.
"Most technologies only use HR to estimate a state of fatigue," said OMsignal. "Few technologies, like OMsignal, can also measure HRV. Only OMsignal adds an additional layer of accuracy by factoring in your breathing, a biometric that can vary (relatively) just as much as your heart rate when exerting yourself."
The garment is made from lightweight, stretchable fabric composed of a polyester, nylon and elastane blend. The material allows the bra to re-shape itself around the wearer's body as they exercise, and is d...
