Scientists have developed a 'smart bra' which can measure the wearer¿s mood to help prevent over-eating and potentially aid weight loss

The bra warns the wearer when she might be prone to reaching for food and also gives her tips to help resist the food. a professor in computer science MC schraefel and human performance from the university of southampton designed this bra which filtered with sensors which monitors skin and hearth activity. The data from the prototype device is analyzed by a smart phone. The device then suggest exercises such as calming breathing exercise.
The bra is a result from a study called Food and mood, for emotional eating.
I would say they should create an app that will send a very uncomfortable shock wave when you try to touch food....lol.
