Piezoelectric Signal Dataset for Knee Joint Flexion Process

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). Finally, the unhealthy group comprises 7 participants clinically diagnosed with knee pathologies (5 females). This dataset supports research on knee joint biomechanics and health diagnostics.
