Fibers, membranes and in general textiles are commonly worn around the body and are therefore ideal materials for the monitoring of vital body functions or for transdermal drug delivery systems. As they are flexible and robust; and present a unique surface-to-volume ratio, they can be used to develop wearable sensors with high wearing comfort and covering large body areas. For instance, optical fiber-based sensors have been used for the supervision of respiration, cardiac output, blood pressure, oxygen saturation, as well as the monitoring of pressure for the prevention of pressure ulcers [1]. Stimuli-responsive polymers that change their molecular structure in dependence of temperature, light or pH can be processed into fibers and membranes for different biomedical applications like highly-sensitive drug carriers with well-controlled delivery [2, 3]. In a recent project with the University hospital of Zurich, we developed a light-responsive membrane that will be used for the delivery of caffeine for preborn infants suffering from lung insufficiency [4]. The same membrane is intended to be used as part of a non-invasive glucose monitoring system. In this seminar, an overview of our research in the field of smart fibers and membranes for sensory and targeted delivery will be given.
