From April 19 to 21, 2024, the 2024 International Forum on Biomechanics in Sports Performance and the 23rd National Academic Conference on Sports Biomechanics was successfully held at the Capital University of Physical Education and Sports. The event was hosted by the Chinese Society of Sports Sciences, organized by the Division of Sports Biomechanics, Capital University of Physical Education and Sports, and Ningbo University, and co-organized by the International Exchange Working Committee.

The conference aimed to encourage interdisciplinary integration among sports science, medicine, engineering, and other fields, promote breakthroughs in basic theories and the translation of key technological achievements in sports science and technology, and conduct in-depth discussions on cutting-edge and hot topics in sports biomechanics. It also sought to contribute to the implementation of national strategies such as building a sports power and a healthy China.

At the conference, the marketing team from Onesense Medical showcased the company’s latest independent innovation—the world’s first 512-channel, wireless, distributed high‑density EMG acquisition system, Oct‑HD. The system brought multiple innovative solutions and advanced concepts to the field of high‑density EMG, attracting significant attention from participants and sparking extensive exchanges and discussions.

In this system, each module can collect 64 channels of EMG data and 9-axis motion and posture data. Through its proprietary synchronization technology, it can support up to 512 channels working simultaneously, enabling stable multi‑module synchronous sampling both online and offline. The system incorporates full‑channel impedance detection technology, helping users accurately evaluate electrode contact quality and effectively avoid interference from human physiological signals and environmental equipment during data acquisition. In addition, the system supports 8 channels of auxiliary input and external device synchronization I/O.

Oct‑HD is equipped with dedicated analysis software that features advanced one‑click analysis functions such as motor unit decomposition, EMG topography, and muscle fiber conduction velocity. Its clean interface design and user‑friendly interaction significantly reduce the learning curve, allowing users to quickly integrate the system into and support research across multiple disciplines and fields.

In terms of product design, the device adopts an advanced R&D philosophy different from traditional high‑density EMG systems, fully leveraging the advantages of industrial design and user experience design. It innovatively uses an electronically controlled self‑locking mechanism on the base station to ensure reliable fixation and stable storage of sampling modules. The flexible electrode connection inside each module features an ingenious push‑down self‑locking structure, achieving a “click‑to‑lock” for the flexible electrodes. The self‑adhesive soft rubber shell, combined with specialized straps, allows modules to be easily fixed to any position on the limbs or trunk.

We look forward to using this exhibition platform to inject new vitality into the innovative development of domestically developed equipment in China, promote the advancement of sports science, and contribute to the realization of the grand goal of building a sports power. We firmly believe that with the joint efforts of all sectors, the field of sports biomechanics will surely embrace a more brilliant and promising future.
