Wearable and flexible health sensing devices are nowadays crucial and the development of multi-sensing wearable textiles for non-invasive motion detection and continuous long-term biophysical signal monitoring is of primary interest. As a matter of fact, the wearable technology market forecast is at more than 20% growth rate annually and it is expected to reach over 40 billion EUR per year in the next 5 years. In this context, a central role is played by composite materials and, among them, graphene based nanocomposites are promising candidates for the development of multi-sensing wearable sensing textiles through screen printing or cast deposition techniques. Recently, several wearable polymeric sensors have been proposed. Most of them mainly focus on two aspects: movement, respiration rate and temperature detection or measurement of biopotential signals. For instance, PDMS based nanocomposites have been proposed for biopotential signal monitoring, replacing conventional electrodes. However, such biopotential sensors generally are not suitable to detect also motion, temperature or other physiological parameters, i.e. to work as multi-sensing elements. The aim of the research project is to overcome this bottleneck producing graphene based coated textiles able to conjugate electrical and piezoresistive properties with the aim of producing multi-sensing wearable sensors by direct deposition on commercial textiles (like T-shirt or fitness bands), without compromising fabric flexibility and stretchability. In addition, the coated textiles will be designed in order to guarantee washability, reusability and to prevent coating detachment. With this purpose, different designs and data processing will be proposed, investigating different polymeric matrices, shapes, sizes, etc. Then, data fusion algorithm will be developed in order to extract all the desired parameters
