Afon Technology is a Welsh medical tech company, who have developed a groundbreaking device capable of non-invasively monitoring blood glucose levels in those who have diabetes. Through the Welsh Government’s SMART Productivity & Design programme, ITERATE worked closely with the company to design and develop a wrist worn prototype. A key challenge that needed to be overcome was that the monitoring technology had to be consistently placed on the wrist – from one user to another. This was achieved by the strap having a rigid half and a flexible half; enabling the user to maintain a constant position in relation to the vein. Using in-house 3D printing, the design team crafted a functional prototype featuring an Apple Watch displaying glucose data, allowing user feedback to be gained.
