Knitted RESi is a knit textile capable of sensing external stress, via a force sensing technical yarn. It can sense pressure, stretch, and any other deformation. Our demonstrator provides live feedback and visualization of the sensor readings. The textile is highly durable and strikingly responsive with little signal-to-noise ratio. It features inherent favorable properties of textiles, e.g. it is lightweight, highly flexible, comfortable on skin, and breathable.
