Nearly forty representatives from industry, academia, research and application sectors attended, including representatives from the China Electronics Industry Science and Technology Exchange Center, the Shenzhen Semiconductor Industry Association, Shenzhen Hospital of Southern Medical University, the Institute of Child and Adolescent Health of Peking University, the Peking University Shenzhen Key Laboratory of System Chip Design, and the Shenzhen Institute of Advanced Electronic Materials. Enterprise representatives included Chipsea Technology, Xicheng Weike, Huawei, Kangyou Health, Yunmai, Lepu Medical (Lifesense Medical), Lefu Scale, Shenzhen Ioula, Daxin Health, and Haidi Health, among others, who gathered to exchange views and jointly offer suggestions for standards development in the field of health measurement.

The seminar was chaired by Du Zeyan, Secretary-General of the Branch. She stated that standards are an important vehicle for industry self-discipline and technological progress, and that this seminar focused on standards development in the field of health measurement, hoping that attending representatives would speak freely and pool their wisdom to jointly establish solid and well-grounded standards.

Guest Remarks

Guests attending the meeting and delivering remarks included Liu Yuanchao, General Manager of the China Electronics Industry Science and Technology Exchange Center; Chang Junfeng, Secretary-General of the Shenzhen Semiconductor Industry Association; Wang Yongjian, Deputy Director of the Department of Critical Care Medicine at Shenzhen Hospital of Southern Medical University; Professor Ma Jun, Director of the Institute of Child and Adolescent Health of Peking University; and He Jin, Director of the Peking University Shenzhen Key Laboratory of System Chip Design.

Liu Yuanchao, General Manager of the China Electronics Industry Science and Technology Exchange Center, pointed out that China has entered an aging society, with the population aged 60 and above growing by about 10 million each year, and demand for home health devices continues to expand. Currently, the field of health measurement still lacks national and industry standards, and there are social phenomena of misleading consumption in the name of health care. The industry's "national team" should take the lead in formulating high-quality standards to guide the standardized development of the industry.

Chang Junfeng, Secretary-General of the Shenzhen Semiconductor Industry Association, stated that Shenzhen has a concentrated semiconductor industry, and the association has long carried out work centered on member services, industry research and enterprise services. He believes that standards should not be limited to a single chip but should cover the complete technology chain from chips and algorithms to complete-device applications, and he hopes that upstream and downstream enterprises will participate jointly.

Professor Ma Jun, Director of the Institute of Child and Adolescent Health of Peking University, noted that child and adolescent health is a national priority. As early as his early years, he collected health data for adolescents and the general population based on the bioelectrical impedance method, and he hopes that data from home health devices can be combined with clinical medical indicators, and he is willing to play a role in the formulation of application-oriented standards.

He Jin, Director of the Peking University Shenzhen Key Laboratory of System Chip Design, believes that health chips address the broad needs of "the elderly and the young," the industry has promising prospects, and standards are an important vehicle for industrial discourse power. He called on all parties in industry, academia and research to collaboratively advance the construction of the standards system.

Wang Yongjian, Deputy Director of the Department of Critical Care Medicine at Shenzhen Hospital of Southern Medical University, pointed out from a clinical perspective that body composition measurement has medical value in scenarios such as chronic disease management, fluid assessment for hemodialysis patients, and early warning of central obesity risk. He suggested that relevant standards clarify product positioning and standardize the detection indicators covered by the standards.

Branch Introduction and Standardization Layout

Du Zeyan, Secretary-General of the Branch, reported on the Branch's work and standardization layout. The Branch focuses on standardization across the full lifecycle of health electronic devices, builds a standards system adapted to AI integration needs, and promotes industry collaboration of "home monitoring—AI analysis—clinical linkage." At the meeting, explanations were given regarding the solicitation of participating units for two group standards, and relevant enterprises, research institutes and testing institutions were invited to actively register to participate in standards drafting.

Standards Discussion

The group standard "Bioelectrical Impedance Chip" was reported on by the drafting group represented by Chipsea Technology (Shenzhen) Co., Ltd., covering the drafting background, framework structure and main technical content of the draft. According to the introduction, the standard specifies technical indicators and corresponding test methods including four-electrode measurement, excitation signal characteristics, impedance measurement dynamic range and measurement error, phase angle error, measurement repeatability, multi-channel consistency, common-mode rejection ratio, temperature drift, electrostatic protection and environmental adaptability.

Attending experts discussed the indicator system, test conditions and determination methods item by item, and put forward revision suggestions on the rationality of indicators and the operability of testing.

The group standard "Four-Electrode Body Fat Scale" was reported on by the drafting group represented by Shenzhen Kangyou Health Technology Co., Ltd. According to the introduction, the standard focuses on regulating metrological performance, impedance measurement performance and body fat rate measurement performance to ensure that the data output by body fat scales is authentic, credible and traceable. The draft classifies products into single-frequency, dual-frequency and multi-frequency according to measurement frequency, and encourages the use of domestically produced BIA measurement chips and communication chips, with application software adapted to domestic operating systems.

Attending experts conducted in-depth exchanges on key indicators such as measurement accuracy, repeatability and body fat rate measurement correlation, as well as test conditions and subject sample design. Enterprise representatives including Ioula Technology, Yunmai, Lifesense Medical, Haidi Health, Xicheng Weike and Shenzhen Heliwei all put forward revision suggestions based on their own product practices.

During a break in the seminar, attending representatives visited and exchanged views at the Peking University Shenzhen Key Laboratory of System Chip Design, gaining a close-up understanding of the relevant testing platforms and experimental environment, and conducting on-site communication regarding actual measurement conditions, testing environment and technical equipment.

During the session on soliciting standards in other directions and free exchange, attending representatives, based on their units' research directions and market pain points, exchanged views on standardization needs in health measurement directions such as blood pressure, heart rate, body composition analysis and wearable devices, and discussed topics such as common industry issues, standard implementation and application, and industrial chain collaboration. The Branch Secretariat will uniformly collect and organize the project initiation suggestions solicited and evaluate their feasibility.

The solicitation of participating units for the two group standards of this seminar remains open, and relevant enterprises, research institutes, testing and certification institutions and experts are welcome to continue participating in the standards drafting work. Next, the Branch will continue to focus on the full lifecycle of health electronic devices, build a five-in-one standards system of "basic general—technical requirements—test methods—data interoperability—service management," and join forces with all parties in industry, academia, research and application to promote the high-quality development of the health measurement industry.
