Microsoft researchers have designed a smart bra which monitors a woman's mood in an attempt to prevent emotional overeating.
The bra contains several removable sensors which monitor heart rate, breathing, skin activity and movement.
In theory, the bra could determine when a wearer is stressed and likely to look to food for relief, Microsoft researchers wrote in a research paper.
It would feed the data to a smartphone app via bluetooth and provide interventions such as deep breathing exercises to help the wearer overcome their urge.
The researchers said the bra predicted emotions "significantly better than chance" after testing it on four women for four days.
