In this paper, we discuss the phototherapy concepts developed by Philips in the EU FP7 PLACE-it project. These concepts demonstrate the use of e-textiles for medical applications in a meaningful way. By introducing a comfortable, wearable technology, Philips has enabled a new world of devices which provide comfortable home treatment of different diseases and complaints. Here, we show concepts and clinical validation, and give insight in the development steps to be taken to build this kind of devices.
