Notice of Participation in 'SENSOR EXPO JAPAN 2024' from September 18 (Wednesday) to September 20 (Friday), 2024

We are developing a battery-less multi-purpose sensor that applies the power generation principle of liquid detection sensors, capable of detecting various external forces and physical changes!

We introduce a battery-less multi-purpose sensor using Mg air batteries. ■ Battery-less Sensor This is a groundbreaking device that applies and further evolves the technology of battery-less liquid detection sensors. The core of this sensor consists of a sensor element that starts generating power when it comes into contact with water, a water bag, and a wireless transmitter (BLE or LPWA) integrated into one structure. When external force is applied, the internal water bag bursts, initiating power generation and activating the wireless transmitter. The most significant feature is its battery-less design, which allows for installation in locations where power supply is difficult and can withstand long periods of inactivity, greatly contributing to labor reduction. ■ Design Versatility This unique design allows it to function as a sensor that responds to various external forces such as pressure, tensile force, shear force, and impact force. By customizing the case design, it can accommodate a wide range of applications. ■ Expected Applications The expected applications are diverse: 1. Drone drop detection sensor 2. Snow accumulation detection sensor in snowy mountains 3. Crack propagation detection sensor in bridge components It has the flexibility to be utilized in various fields and situations, depending on the customer's ideas.

Detects minute liquid leaks! The sensor itself generates power, so no external power supply is needed.

Power-free liquid detection! Revolutionary Mg-air battery method "Liquid Detection Sensor" The Liquid Detection Sensor is based on Mg-air battery technology and generates power when it comes into contact with water or other liquids. It operates without any external power supply for the sensor part, and notably, it can reliably generate power and detect not only water but also urine and blood. ■ Battery-less Eliminating the need for power supply, which was essential for conventional liquid sensors, enables operation without restrictions on installation locations. ■ High sensitivity detection capability Achieving a high-sensitivity design that can reliably detect even a few drops of liquid. It can detect minor liquid leaks and condensation without missing them. ■ Compact and flexible installation With a slim and small design, it can be easily installed in narrow spaces and gaps in equipment where conventional sensors would be difficult to place. It can be utilized in various locations such as around piping, under floors, and in ceilings. ■ Notification system The detected information is implemented to be notified via email to smartphones or computers. Even in sites requiring constant monitoring, remote situation checks are possible, enabling prompt responses. *For more details, please refer to the PDF document or feel free to contact us.

We will be exhibiting at the J AGRI (J Agri) / Agricultural Materials EXPO held at Gran Messe Kumamoto from May 22 (Wednesday) to May 24 (Friday), 2024. 【Booth Number】: B1-43 Outdoor Exhibition Area Japan's largest comprehensive exhibition for agriculture and livestock, Agricultural WEEK, will be renamed J AGRI starting in 2024. This is a place where you can actually see, touch, and compare products. At our booth, we will showcase our lightweight resin flooring boards "JULIGHT / SUPER JULIGHT / RAKURAKUBAN" along with new products. Starting with the agricultural-specific flooring board "RAKURAKUBAN," which can be easily laid in various scenes such as around greenhouses, agricultural work sites, temporary parking lots, for the movement of agricultural machinery and light trucks, and for protecting truck beds, there are various ways to use the lightweight resin flooring boards "JULIGHT / SUPER JULIGHT series." We offer a variety of sizes and protrusion shapes tailored to customer needs, and they are lightweight enough to be carried by hand, with excellent impact resistance, as well as superior water resistance, weather resistance, and durability, providing outstanding features not found in plywood or steel plates. We sincerely look forward to your visit.

Dear Sir or Madam, We hope this message finds you well and that your company continues to prosper. FUKUDA will be exhibiting at the 28th INTERPHEX Week Tokyo. At the exhibition, we will be showcasing 100% inspection equipment compliant with Container Closure Integrity Testing (CCIT) standards, as well as sampling inspection machines. We sincerely invite you to visit our booth at this opportunity and would greatly appreciate your attendance despite your busy schedule. Yours sincerely, [Dates] May 20 (Wed) - 22 (Fri), 2026 10:00-17:00 (JST) [Venue] Makuhari Messe, Japan 8 Hall Booth No. 41 - 36
