LIBELLE is a product-service system that enables people going through fertility treatments to manage and balance their personal journey. It contains a smart device that monitors heart rate and sleep. It also provides a removable heat pack, which helps with abdominal pains. The device links with an app to help manage the full fertility treatment. Libelle can be worn two ways, in the pocket of a garment or on the wrist. This system helps users manage medication and appointments. Libelle’s buddy system allows users to chat with people on a similar journey to them. The journal feature allows them to highlight the good moments and recognise their strength to overcome the difficult ones.
