Check out this fashion design project by Studio Roosegaarde that makes the clothing turn transparent when the users hear rate increases... The project is called INTIMACY 2.0 and it explores the relation between intimacy and technology.
I don't know about you but this would be pretty interesting to see on the dance floor... hhmmm.
Its high-tech garments entitled 'Intimacy White' and 'Intimacy Black' are made out of opaque smart e-foils that become increasingly transparent based on close and personal encounters with people. INTIMACY 2.0 features Studio Roosegaardeʼs new, wearable dresses composed of leather and smart e-foils which are daringly perfect to wear on the red carpet. In response to the heartbeat of each person, INTIMACY 2.0 becomes more or less transparent.
