Knee joint health

Six flexible piezoelectric sensors were evenly attached around the patella of the knee joint to capture patellar motion signals during the knee flexion process. This dataset includes data from three distinct participant groups categorized by knee joint health status. The healthy group consists of 27 participants with normal knee joints (10 females). The subhealthy group includes 15 participants from Beihang University experiencing mild knee discomfort (8 females).
