2025-03-13 02:00Summary of the Conference Call on Brain-Computer Interface Industry Industry Overview - The discussion revolves around the brain-computer interface (BCI) industry, focusing on the future development of both invasive and non-invasive technologies [1][1]. Core Insights and Arguments - The future of BCI will involve a dual approach, with both invasive and non-invasive methods being developed. Invasive methods have already achieved human clinical trials but are expected to take an additional 3-5 years for commercialization. Non-invasive BCI products have seen some commercialization, but their effectiveness in capturing brain signals is inferior to that of invasive methods, making it unlikely for non-invasive methods to replace invasive ones [1][1]. - The primary focus of future research and development will be on invasive BCIs, while the commercialization of non-invasive BCIs is expected to accelerate, providing more data and support for the industry [1][1]. Key Technologies and Metrics - The core technologies of BCI include electrodes, chips, and algorithms [2][2]. - Invasive electrodes are primarily focused on flexible electrodes made from silk protein, while non-invasive electrodes utilize EEG technology [3][3]. - Common algorithms used in BCIs include adaptive filtering algorithms, time-frequency analysis algorithms, spatiotemporal analysis algorithms, and pattern recognition algorithms [4][4]. - Key performance metrics for BCIs are categorized into performance indicators (response time, accuracy, output command quantity, and throughput) and usability indicators (ease of use, longevity, robustness, and safety) [4][4]. Current and Future Applications - Current applications of non-invasive BCIs are primarily in rehabilitation medicine, targeting populations such as stroke recovery and depression patients. Invasive applications include deep brain stimulation (DBS) for patients with Parkinson's disease, Alzheimer's, and epilepsy [4][4]. - As technology advances and medical commercialization progresses, there is potential for deep integration of BCIs with various industries, such as virtual reality (VR) and the Internet of Things (IoT) [4][4]. Notable Companies and Developments - Companies to watch in the BCI space include: 1. Rehabilitation sector companies (Chengyitong, Xiangyu Medical, Weisi Medical) that are making progress in the commercialization of non-invasive BCIs, with potential mergers or investments in this area [5][5]. 2. Gaode Infrared, which announced on March 8 that it is developing a leading 65,000-channel bidirectional system [5][5]. 3. Jingyu Medical, a leader in DBS, which has passed regulatory approval and is well-positioned to compete with Medtronic [5][5].
