Yingke learned that Suzhou Lingdong Jiaxin Technology Co., Ltd. (hereinafter referred to as "Lingdong Jiaxin") recently completed a Series A financing, with a financing amount of nearly 100 million yuan. In this round of financing, several industrial parties and financial investment institutions such as Jinqiu Fund, SMIC Juyuan, Ruicheng Investment, and Runzhang Venture Capital were introduced, and Mushi Capital served as the long - term strategic financial advisor.

Lingdong Jiaxin was established in 2021. It is an enterprise that develops sensor solutions based on piezoelectric materials and semiconductor technology. Its application scenarios cover multiple fields such as intelligent robots, smart wearables, new energy, and lithium - ion batteries.

The core founding team members all come from large domestic electronic technology companies and have decades of experience in management, R & D, and mass production.

In terms of business path, since its establishment, the company has adopted a dual - track promotion strategy of "mature business + cutting - edge technology": on the one hand, it establishes an income foundation and expands its customer base through the large - scale shipment of products in the mature market; on the other hand, it promotes the R & D and implementation of high - growth technologies around emerging application scenarios.

In the field of service robots in the mature market, Lingdong Jiaxin has launched an intelligent piezoelectric sensor module, with full - stack self - research from core materials to system solutions. The product has advantages in terms of integration, sensitivity, volume, and power consumption. It has currently entered the supply systems of many domestic and international mainstream cleaning robot manufacturers.

It is understood that the company's intelligent piezoelectric sensor module has shipped more than 10 million units in 2025, and it is expected to further increase to more than 20 million units in 2026, occupying a leading position in the niche market.

In the direction of new technologies, the company focuses on the R & D of flexible piezoelectric sensors based on PVDF (polyvinylidene fluoride). As a typical organic piezoelectric material, PVDF has the characteristics of light weight, good flexibility, bendability, and a wide frequency response range. Its piezoelectric effect comes from the polarization change of the molecular chain under the action of external force, giving it a natural advantage in weak force sensing scenarios. It is suitable for fitting complex curved surfaces and achieving high - density distributed sensing. Therefore, it is considered one of the important material paths in the "electronic skin" direction.

Guansai Xin, the founder, said in an interview with Yingke, "Most of the tactile technologies on the market are based on principles such as magnetism, force, capacitance, voltage, and resistance. PVDF has relatively more advantages in terms of sensitivity and stability." Around this material system, Lingdong Jiaxin has mastered the core formula and established a complete manufacturing process. It is one of the few domestic teams with PVDF mass - production experience.

Based on the above capabilities, the company has launched a PVDF flexible tactile sensor product for the embodied intelligence scenario. This product can be applied to links such as dexterous hands, grippers, and data collection to improve fine operation and perception capabilities.

As the demand for high - quality tactile data in embodied intelligence increases, tactile sensors are gradually moving from "auxiliary perception" to "core input", and the importance of related products is also increasing. Currently, this product has achieved small - batch shipments to some leading customers, and the volume will gradually increase as production capacity is released.

In the process of technology promotion, the company is also strengthening industry - university - research cooperation. Guansai Xin, the founder, said in an interview that Lingdong Jiaxin is cooperating with relevant research institutions such as Shanghai Jiao Tong University and the Chinese Academy of Sciences to integrate the characteristics of various materials and achieve true embodied intelligent tactile perception.

In addition to the robot direction, Lingdong Jiaxin is also deploying in the field of lithium - ion battery safety. The company's developed PVDF - based flexible ultrasonic monitoring solution can be embedded inside the battery to monitor the production, use, and charging processes in real - time and issue early warnings. Guansai Xin said that the goal of this solution is to "control the safety hazards of lithium - ion batteries from the source". Currently, this project has cooperated with leading domestic lithium - ion battery companies and is expected to be ready for mass production in two to three years.

In terms of commercial expansion, the company has also launched an overseas layout. In more than a year, it has approached nearly ten overseas customers and obtained the first batch of orders. Some projects have entered the proof - of - concept and verification stages. Currently, the overseas expansion starts with piezoelectric ultrasonic sensors and simultaneously promotes the introduction of tactile products in the overseas market.

After the completion of this round of financing, the funds will be mainly used for the R & D investment of PVDF - based flexible sensors in the directions of embodied intelligence and lithium - ion battery safety, as well as the expansion of the overseas market.
