The bra was outfitted with a gyroscope and an accelerometer as well as an electrocardiogram and electro-dermal sensors to monitor stress. The bra communicated with a smartphone app to help track moods and stop emotional over-eating.
Don't look for this Microsoft smart bra to hit stores anytime soon.
Said Microsoft researcher Asta Roseway, "It was very tedious for participants to wear our prototyped sensing system, as the boards had to be recharged every three to four hours."
