Journey between designer Salome Bazin (Cellule Studio) and myself, a bioengineering scientist, aiming to shape the future of cardiovascular healthcare by creating conversations with citizens and cardiac patients in particular. Two milestones of our collaboration have been “Big Heart Data”, a series of 50 3D printed hearts, and “Kalostasis”, an immersive exhibition illustrating the flow of blood through the aorta. Our third project “IchO” will be a phone app to record and visualise heart beats.
