Our company is advancing the development and commercialization of pressure-sensitive sensors for robotic hands, utilizing the membrane technology we have cultivated over many years. Our pressure-sensitive sensors come in two types: "pressure-sensitive ink type" and "capacitive type," both of which are being developed for practical use in robotic hand applications. Both types adopt a structure that maintains a constant distance between electrodes when not loaded, achieving highly reproducible detection performance, along with features of being thin, lightweight, and highly durable. Furthermore, by dividing the sensor surface into multiple detection areas (cells), we can identify the contact position, contributing to the delicate gripping control of robotic hands.

Starting in May 2025, we began mass production of the "AT7 Series," a gauge pressure high-precision sensor that is among the smallest in the world. The "AT7 Series" is a semiconductor pressure sensor in an ultra-compact 4×4mm package that supports high-resolution digital signal output. The miniaturization of the package and the use of folded leads have achieved space-saving, reducing the mounting area by over 72% compared to our conventional products. It can output a digital signal with an accuracy of ±1.5% FS at temperatures ranging from 0 to +85°C, making it suitable for a wide range of applications, including electrical equipment, medical devices, and industrial equipment.

Pioneering the CASE era with a high-speed, high-reliability interface. The FFMS1 connector is a one-touch lock FPC connector equipped with a "one-action" locking mechanism, suitable for a wide range of applications including in-vehicle internal wiring, communication devices, and industrial equipment. It adopts our unique one-action structure that ensures a secure fit simply by inserting the FPC. This significantly reduces the labor required by customers and enables the complete automation of the FPC insertion process.

To address heat dissipation due to the high performance and high density of CPUs/GPUs in data centers, and to meet a wide range of requests, we have developed a vapor chamber (VC) heat spreader. The heat spreader is a component that efficiently diffuses and dissipates heat generated from semiconductor chips. It is attached to the chip surface and optimizes heat transfer to cooling devices such as heat sinks and liquid cooling systems, playing a role in suppressing the temperature rise of the chip. Typically made from highly thermally conductive metals like copper or aluminum and having a flat shape, this product incorporates a porous body (wick) utilizing capillary action inside a hollow metal plate and adopts a flat heat pipe structure filled with a working fluid.

The CM08 series is a compact round waterproof connector developed for connecting various sensors. By adopting a diameter of 10mm for the M8 screw fitting size and an integrated molded structure, it achieves a smart and compact shape. Using the CM08 series enables a reduction in wiring work and the miniaturization of equipment.

Our company has developed a cable-type piezoelectric sensor by utilizing the design and manufacturing technology of ultra-fine coaxial cables. The cable-type piezoelectric sensor has a cable shape and responds to physical deformation, allowing it to detect various movements such as vibration, impact, bending, stretching, and strain along its entire length. With an outer diameter of just 0.5mm, it is extremely thin, flexible, and lightweight. It does not require power supply and features a coaxial structure, making it highly resistant to noise.

Our company has developed a tower-type vapor chamber for air cooling to address heat dissipation issues caused by the high performance and high density of CPUs/GPUs in data centers, as well as to meet a wide range of customer demands. The tower-type vapor chamber integrates a cylindrical pipe on top of a typical flat vapor chamber, creating a structure that connects the internal space, with heat dissipation fins attached to the cylindrical section. This developed product achieves a 15% reduction in thermal resistance compared to conventional tower-type air cooling units that combine copper plates and heat pipes, and it is an air-cooled solution that can be used in existing data centers without water cooling facilities, achieving performance improvements comparable to water-cooled cooling effects.

The CM03A connector is a waterproof connector compatible with the DeviceNet standard Mini-style. It allows for the interconnection of PLCs from different manufacturers and various field devices (displays, solenoid valves, inverters, I/O terminals, operation terminals, robots, NC, etc.). The conventional CM03A uses soldering for wiring, which requires a significant amount of time for the wiring process. Focusing on reducing this work time, we have developed a crimp-type connector and contacts.

We have developed an ultra-compact Board to Board connector that pursues miniaturization with a mating height of 0.5mm, signal contact pitch of 0.30mm, width of 1.55mm, and a length of pitch total + 2.48mm. By leveraging our technological capabilities in connector development, we enhance our customers' design flexibility and contribute to the advancement of smart devices. Additionally, this connector reduces volume by approximately 40% compared to conventional products with the same number of pins, contributing to a reduction in environmental impact by decreasing material usage.

With the trend towards smaller and thinner mobile devices, the demand for further miniaturization of FPC connection connectors is increasing. In response to this, we have developed the FFA1W series connector. This product features a terminal pitch of 0.15mm, making it one of the smallest in the industry, and a height of 0.55mm when mated with FPC. Even at this minimal level, our unique locking structure and cable lock mechanism maintain high performance. Furthermore, this product contributes to further miniaturization of wearable devices and similar applications, as the cable lock also serves as a signal connection terminal.

Fujikura Ltd. (President and CEO: Naoki Okada) will begin mass production of the "AT7 series," a high-precision gauge pressure sensor that is among the smallest in the world, starting in May. The new "AT7 series" has reduced the package size to 4mm x 4mm and features an original inward-folded lead design. As a result, it has successfully reduced the mounting area on the circuit board by 72% compared to the previously smallest "AG series" pressure sensors. [Key Points] - Achieved further miniaturization with a package size of 4mm x 4mm and the adoption of inward-folded leads - Reduced the occupied area by 72% compared to the previously smallest "AG series" products - Suitable for a wide range of applications despite its compact size - Achieves high resolution and fast sampling rates
