The insoles, together with the integrated sensors and conductive tracks, are produced in just one step on a 3D printer. (Photograph: Marco Binelli / ETH Zurich) Researchers at ETH Zurich, Empa and EPFL are developing a 3D-printed insole with integrated sensors that allows the pressure of the sole to be measured in the shoe and thus during any activity. This helps athletes or patients to determine performance and therapy progress. Running data soon to be read out wirelessly . Tests showed the researchers that the additively manufactured insole works well. "So with data analysis, we can actually identify different activities based on which sensors responded and how strong that response was," Siqueira says. The sensors are individually placed.
