The Bubelle dress changes colour depending on your mood The Bubelle Dress is made up of two layers, the inner layer contains biometric sensors that pick up a person's emotions and projects them in colours onto the second layer, the outer textile The sensitive dress, which was designed by electronical giants Philips, works by monitoring physical changes associated with different feelings. Emotions such as stress, arousal, or fear affect the body's temperature and sweat levels and these generate the light that changes the pattern and colour on the dress. Ingrid Bal from Philip's Design said: "You could programme the material so that it turned red if you were angry or stressed, or green when you're calm." Should the prototype ever hit the high street it would help British couples to communicate better. It was developed as part of the SKIN Probe Project, a research programme concerned with what lifestyles might be like in 2020. Time magazine named the impressive clothing as the best fashion invention of the year. Ms Bal said: "We were interested to see how technology may affect our lives in the future and to provoke debate. We are asking: 'Would the idea of emotional clothing be something we will wear in 10 years time?'" Scientists at the Dutch firm also designed electronic tattoos which could also change design based on mood as part of their design project. A spokeswoman added: "In much the same way as make-up is put on and taken off to suit the occasion, a tattoo could alter whenever desired. "The tattoos could even change in response to gestures or emotions."
