Microsoft developing 'smart bra' - Telegraph In the research paper, the scientists explain that the bra form factor was chosen because it allows the sensors to sit close to the heart. The sensors are embedded in conductive pads which sit at the centre of the user's sternum, on each side of their ribs and in the bra cup, just under the breast. The scientists were then able to correlate this real-time data with historical information about the wearer's emotional eating patterns, and trigger an intervention via their mobile phone before they start comfort-eating. Designs for the smart bra were revealed in a research paper from a team of scientists at Microsoft Research, entitled Food and Mood: Just-in-Time Support for Emotional Eating. The paper focuses on "building a persuasive system for behaviour modiﬁcation around emotional eating." 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. "Based on these results, we conclude that building a wearable, physiological system is feasible," the scientists said. However, we will continue to explore how to build a robust, real-world system that stands up to every day challenges with regards to battery life, comfortability, and being suitable for both men and women.
