Participants wore the bra sensing system and reported their emotions for about 4-6 hours a day over a period of approximately four days.
The scientists admitted that it was very tedious for participants to wear the prototyped sensing system, as the boards had to be recharged every 3-4 hours, requiring them to remove their bras.
Wearable technology is increasingly being used to monitor a range of health conditions.
Last month saw the release of a Twitter-connected bra that tweeted every time it was unhooked to encourage women to self-examine their breasts.
And last year a patent was awarded to a US firm that was working on a wearable device that analysed breast heat in order to detect cancer.
Meanwhile in response to a series of rapes in India, three engineering students developed a bra loaded with sensors and an electronic circuit that is activated when someone attempts to grope a woman wearing it.
