Tohoku Electric Power and TOPPAN Edge begin sales of liquid leak detection system using printed wiring and RFID technology
*Battery-free and compatible with a wide range of liquids such as oil, water, and chemicals*
Tohoku Electric Power Co., Ltd. (Head Office: Sendai City, Miyagi Prefecture, President and CEO: Kojiro Higuchi, hereinafter referred to as
Tohoku Electric Power) and TOPPAN Edge Co., Ltd. (Headquarters: Minato-ku, Tokyo, President and Representative Director: Hideki Soeda, hereinafter referred to as
TOPPAN Edge) has developed a leak detection system for oil, water, water-based chemicals, etc. (hereinafter referred to as the “system”) that combines printed wiring (*1) and RFID (*2) technology, and has developed a system for detecting leaks of oil, water, water-based chemicals, etc. We have been conducting demonstration experiments at power plants. (*3)

Now that the development and demonstration of this system has been completed, we will begin selling this system to companies and organizations from May 30, 2024.
From now on, TOPPAN Edge will manufacture and sell the product, aiming to introduce it to approximately 100 business locations over the next three years, while Tohoku Electric Power will cooperate in sales promotion and both companies will expand sales.

In addition to not requiring a power source, this system uses printed wiring, which is cheaper than conventional metal wiring, and allows for quick and accurate detection of liquid leaks even in locations that are difficult to visually check. Not only in power plants, but also in factories that handle liquids such as petrochemicals and pharmaceuticals, it saves labor in patrol and inspection work and minimizes damage to equipment, contributing to reduced production costs for companies and organizations that have introduced it.

Tohoku Electric Power and TOPPAN Edge will continue to work to provide new value toward the realization of a smart society by using the latest technology to improve the sophistication and efficiency of operations.

*1 Printed wiring is a technology that prints electrical circuits using special ink.
*2 RFID (Radio Frequency)
Identification is an automatic recognition technology that uses wireless communication such as electromagnetic fields and radio waves to read and write information on IC tags and other devices without contact.
*3 Announced on June 21, 2022 “Tohoku Electric Power and Toppan Forms develop a liquid leak detection system that utilizes printed wiring and RFID technology.”
Demonstration experiments will be conducted at the Shin-Sendai Thermal Power Plant from June.”

Liquid leak detection system (RFID tag and tape-shaped detection part) (C) TOPPAN Edge Inc.
* ■ Mechanism of liquid leak detection*
This system combines a tape-shaped detection section with an electric circuit printed with special ink and RFID technology, and is powered by radio waves from an RFID reader. The electric circuit of the detection part has a characteristic that the energization status changes when oil, water, chemicals, etc. adhere to it, and the RFID tag connected to the detection part senses this change and acquires the information of the RFID tag through the RFID reader. This is a system that allows you to check for leaks.

* ■ Features of liquid leak detection system *
* ・Compatible with various liquids with two types of tape-shaped detection parts*
There are two types of tape-shaped detection parts, one for oil leaks and one for water/chemical leaks, and by using the appropriate one, it can be used for various liquids.
For oil leaks (left)/For water/chemical leaks (right)
* ・By combining a tape-shaped detection part and an RFID tag, it is possible to immediately inspect areas that are difficult to see visually.*
This system uses a tape-shaped detection part and an RFID tag, making it possible to instantly check for liquid leaks in areas that are difficult to inspect by simply reading them with an RFID reader. This makes it possible to reduce inspection work that was previously done visually.
In addition, with conventional visual inspection, it was difficult to detect unless liquid had seeped out from the exterior plate covering the pipes, but since the detection part of this system is tape-shaped, it can also be detected inside the exterior plate covering the pipes. Since it can be installed, it is possible to detect liquid leaks early.
RFID tags are activated by radio waves from an RFID reader, so there is no need to install a power cable or batteries, and in addition to being able to install them anywhere, it also reduces the burden of maintenance such as battery replacement.

* ・Achieved significant price reduction by using printed wiring technology* Compared to detection circuits using metal wiring, this system uses fewer raw materials and can be produced inexpensively and in large quantities, making it possible to introduce it at a lower cost than a general monitoring system for liquid leak detection.
