A compact biomechanical dynamometer and adjustable strengthening device for the hand and wrist. It measures force and motion, then streams every rep to a companion app.
PMARC began as a NASA Space Grant funded research project for astronaut resistance training, where long stretches in microgravity quietly erode muscle and bone. It is now an independent project, and that same precision drives what it does best on the ground: hand and wrist strength training and rehabilitation. An embedded module captures force, repetition, and range of motion in real time, turning every squeeze into data you can actually use.
A calibrated load path reads the force of every squeeze in newtons, captured continuously rep after rep, so progress shows up as a number you can trust.
An onboard motion sensor follows the orientation and range of motion of the hand and wrist, so a session is more than a single peak. You see how you moved, not just how hard.
A wireless link pushes readings straight to your phone the moment they happen. No cables, no docks, no setup. Pick up the cube and start.
Resistance tunes across a wide range, so one cube carries someone from a gentle warm up through full training load as their grip comes back.
The companion app connects to the cube, shows the live reading, records timed sessions, and exports the data as CSV. Clean, fast, and built around the numbers that matter.
