Microsoft Designing 'Smart Bra' to Help Women Avoid Overeating

A "smart bra" that would monitor a woman's heart activity in order to track her moods and prevent her from overeating is being developed by researchers.

Studies have shown that people tend to desire calorie-rich foods when they're bored, stressed or discouraged. When sensors in the bra detect heart signals indicating such emotions, they would send a warning message to the woman's smartphone to caution her against bad food choices, CNNreported.

Why did the researchers at Microsoft and a U.S. and U.K. university decide to use a bra?

"First, we needed a form factor that would be comfortable when worn for long durations," they wrote in a research paper published online, CNNreported. "The bra form factor was ideal because it allowed us to collect (electrocardiogram data) near the heart."

The team said more research is needed before a smart bra is actually a viable product. For example, the sensors need to be charged every three to four hours, which limits how long the bra can be worn.
