Chinese-Made Q-Series Crash Dummy Abdominal Pressure Sensor Enters Mass Production, Breaking Overseas Technology Monopoly
Awarded National Invention Patent, CE and RoHS Certified; Performance Reaches Global Advanced Benchmarks
Shenzhen Shenmei Technology & Testing Equipment Co., Ltd. today announced the mass production of its independently developed Abdominal Pressure Twin Sensor (APTS) for Q-series automotive crash test dummies. As the first domestically engineered abdominal pressure sensing solution with full independent intellectual property rights in China, the product delivers measurement accuracy on par with global industry-leading counterparts, with superior performance in several key indicators, ending the long-standing exclusive supply monopoly held by overseas manufacturers.
The product has been granted a national invention patent and holds full CE and RoHS certifications, meeting all regulatory and market access requirements for both domestic and international automotive safety testing markets.
1. Industry Background: Core Sensors Long Reliant on Imports, Strong Demand for Localization
In automotive passive safety testing, abdominal pressure sensors are core measurement components installed in pairs inside the abdominal cavity of Q-series child crash test dummies. They capture real-time pressure load and dynamic curve data during collision events, serving as the critical data source for evaluating abdominal injury risk from child restraint systems and vehicle occupant protection systems.
Leading global safety standards — including UN ECE R129 (Enhanced Child Restraint Systems), China’s GB 27887 Motor Vehicle Child Occupant Restraint Systems, and the China New Car Assessment Programme (C-NCAP) — all mandate the use of abdominal pressure sensors for child occupant injury assessment. With rising safety standards for new energy vehicles and stricter requirements for child passenger protection, market demand for high-precision, high-reliability abdominal pressure sensors continues to grow year on year.
Previously, France-based Transpolis was the only commercial manufacturer of this product worldwide. Domestic automakers, testing laboratories and research institutes relied entirely on imported units, facing persistent pain points including long lead times, high procurement costs, slow after-sales calibration support, and limited customization options. Localization of core testing components has become an urgent priority for China's automotive testing supply chain.
2. Technological Breakthrough: Core Performance Meets International Advanced Standards
The newly launched abdominal pressure sensor portfolio covers all Q-series child dummy models — Q1/Q1.5, Q3, Q6 and Q10 — with multiple nominal diameter specifications. It is fully compatible with mainstream crash data acquisition systems and laboratory test setups.
Key Technical Specifications
· Measuring range: 0–10 bar, with overload capacity ≥ 20 bar
· Comprehensive accuracy: Better than 0.35% F.S.
· Operating temperature: Full temperature compensation across 0°C to 60°C
· Biomimetic design: Fluid-elastic inner bladder structure, with static stiffness response curve highly matched to human abdominal soft tissue
· Interface: Industrial-grade connector as standard, compatible with global mainstream crash data acquisition systems; customizable cable length
· Impact durability: Withstands over 10,000 standard impact cycles with excellent long-term repeatability
Benchmarking verification conducted by an authoritative third-party laboratory confirms that the product's core metrics — including peak pressure measurement deviation, response time, data linearity and repeatability — are highly consistent with equivalent products from Transpolis. It delivers superior performance in impact fatigue life, long-term zero-point stability and wide-temperature adaptability, and can directly replace imported units in formal crash testing and certification trials.
3. Full Independent Control: Invention Patent and Complete International Certifications
As a flagship patented product developed in-house, the abdominal pressure sensor was fully engineered by our R&D team — from biomimetic structural design and micro signal conditioning circuitry to high-impact sealed packaging technology — achieving full independent control over core technology and manufacturing.
Independent Intellectual Property
The product’s core technology has been granted a National Invention Patent of China (Patent No.: ZL 2023 1 1663964.X), supported by multiple utility model patents covering fluid-elastic coupled biomimetic structure, high-impact sealing technology and micro pressure signal calibration methods. This complete IP portfolio eliminates the risk of overseas technology bottlenecks.
International Compliance Certifications
· CE Certification: The product complies with EU directives on safety, health and environmental protection, enabling direct market access across the EU and all regions recognizing CE certification, suitable for export and international laboratory deployment.
· RoHS Compliance: Manufactured in strict accordance with EU RoHS environmental directives, restricting hazardous substances such as lead, mercury and cadmium. It meets global automotive supply chain environmental compliance standards and fits the green procurement systems of automakers and Tier 1 suppliers.
With complete intellectual property rights and international certification systems, the product serves both the domestic market and overseas automotive testing and manufacturing clients, with global market competitiveness.
4. Customer Value: Local Supply, Cost Efficiency and Responsive Support
While delivering equivalent testing accuracy to imported products, our domestically developed abdominal pressure sensor brings multiple core benefits to customers:
1. Cost advantage: Localized supply significantly reduces procurement costs by over 30% compared to imported equivalents, while eliminating exchange rate fluctuations and cross-border logistics risks.
2. Faster delivery: Production capacity is based domestically, with standard models kept in stock, greatly shortening lead times. Expedited channels are available for urgent orders, solving the long lead-time issue of imported products.
3. Localized service: Onshore calibration, maintenance and technical support eliminate the need for overseas factory returns, improving after-sales response time by over 80%. Value-added services such as on-site installation, commissioning and test solution adaptation are also available.
4. Flexible customization: Custom development for special measuring ranges, interface types and cable specifications is supported, adaptable to customers’ non-standard testing needs and new dummy R&D projects.
5. Application Scenarios
The product is widely applicable across automotive passive safety testing scenarios:
· Full-vehicle frontal, side and rear impact crash tests
· Regulatory certification and performance R&D testing for child safety seats
· Development and validation of vehicle restraint systems (seatbelts, airbags)
· Crash safety research at testing authorities, universities and research institutes
· Spare parts supply for dummy manufacturers and maintenance service providers
