New study published on IEEE Explore Sensors journal (Validating commercial wearable sensors for running gait parameters estimation). TgForce was one of the five running sensors tested.

Interesting excerpts from the study:
“However, TgForce was the only wearable sensor to be valid (r>0.70) in estimating IVLR (instantaneous vertical loading rate).”

“Between the five sensors tested in this study, potential buyers aiming to monitor VLR (Vertical Loading Rate) should choose TgForce (TgForce_Z) to get the best estimates (with a tight attachment).”
