A hockey stick fails from the inside. Microcracks form in the carbon fiber, matrix delamination spreads through the layup, and the blade-shaft junction accumulates fatigue, invisibly, across hundreds of shots. By the time it breaks, the damage was done long before the moment.
SubVU puts sensing directly into the tape. Not the stick. The tape. The layer that equipment managers already replace every one to three games becomes the measurement system. We read the signals the structure has always been producing and turn them into one thing: a clear answer on when a stick needs to come out of rotation.
SubVU is collecting used hockey sticks for materials research. We test real failure modes under real conditions -- blades that cracked mid-pass, shafts that snapped on a slap shot, sticks retired after a season of abuse. Your old gear becomes data.
We're in early development and selectively talking to NHL and AHL equipment staff, performance directors, and technical collaborators. If that's you, reach out.
