3D-Printed Insoles Measure Therapy Progress, Athletic Performance

Researchers are developing a 3D-printed insole with integrated sensors that allows the pressure of the sole to be measured during any activity. The technology could be a boon for patients to determine therapy progress — and for athletes to measure performance.

“You can tell from the pressure patterns detected whether someone is walking, running, climbing stairs, or even carrying a heavy load on their back – in which case the pressure shifts more to the heel,” explains co-​project leader Gilberto Siqueira , Senior Assistant at Empa and at ETH Complex Materials Laboratory.
