This thesis investigates and explores new relationships between jewellery, technology and the wearer, based on the interplay between “form & function”. Through the exploration of contemporary jewellery and the use of Critical Design methods, this thesis provides a new perspective on designing interactive jewellery, which is based on the dynamic forms of the object. Taking a research through design approach, I designed and built four explorative prototypes to probe new research in the field of wearables. To explore this field, I conducted a self documentation study with four participants to gather data about their relationships with jewellery and their experiences with the prototypes. These explorations draw on the proposition, that transformative and dynamic forms can contribute to wearable design practices, as they allow wearers to become co-creators of their experience. This can open up new possibilities for aesthetic experience, as jewellery becomes triggers of new experiences and r
