3D printed sensors to measure contact force in climbing (starting with piezoresistive ink)
Commercially available sensing elements have been used by the Sensory-Motor System Lab to study contact forces in bouldering. These sensing elements are quite expensive and are limited to holds with one distinct point of force application, e.g. in the case of crimps (picture above) or pockets.
Keywords: climbing holds, sensors, 3D printing
Nowadays, however, volumes grasped by two hands at the same time are more and more common in competitions (picture below).
3D printing opens new avenues for integrating sensors directly into the holds, measuring forces at different parts of the hold. The ease and economy of these sensors seems quite promising to further push the monitoring of contact forces in climbing. This is not only interesting for researches but also for the media coverage of competitions (climbing is part of the 2020 Olympics).
