Liquid Leak Detector: A Battery-Free Innovation in Sustainability and Performance

February 10, 2025

The Power of Energy Harvesting

Leaks are always unplanned and unexpected happening at the most inconvenient times. So why do typical leak detection products require maintenance such as ensuring the batteries are still viable, or power is running to a wired detector?

Enter the Wireless/Battery-free leak detector that utilizes Gemns™ Energy Harvesting technology. By transforming kinetic energy into electrical power, it can send real-time alerts when a leak is detected, without any maintenance. Set-it-and-forget-it. This groundbreaking system makes the detector both environmentally friendly and exceptionally reliable.

The secret behind this battery-free technology lies in its energy-preloading mechanism and unique leak-sensing element. A mylar-coated paper strip features a small, uncoated section that serves as the detection zone. When exposed to liquid, this section breaks down and disintegrates, triggering the device to release stored energy and initiate the notification process.

To preload energy, users swipe a magnetic tray along the bottom of the device, causing the generating magnet to rotate and store energy in a permanent magnetic field. This stored energy is perpetual, meaning it never degrades over time. It remains forever ready to deliver 3 millijoules of energy. That is enough to cold-boot the ARM Cortex-M4 processor and send a Z-Wave-enabled alert through a series of redundant transmissions.

A Simple but Powerful Detection Mechanism

The leak detection mechanism is elegantly simple and effective. The sensing area, a small indented section on the underside of the device, is designed to attract and detect trace amounts of liquid. What makes this technology even more impressive is the power of its signal. The device sends more than a dozen redundant transmissions at an impressive 14-dBm output level, ensuring that the message is received by the Z-Wave hub even in challenging environments.

Why Battery-Free Matters

For businesses and homeowners alike, eliminating the need for batteries is a game-changer. Traditional leak detection systems rely on batteries, which require regular maintenance and pose environmental risks due to hazardous waste. Our Liquid Leak Detector solves these issues with the power of energy harvesting, making it a truly maintenance-free solution.

Not only does this technology improve the environmental footprint, but it also enhances operational reliability. In many battery-powered systems, the battery may fail before a leak is detected, leaving businesses and homes vulnerable to water damage. With this solution, there’s no risk of battery degradation over time, making it ideal for long-term, worry-free monitoring.

Designed for Convenience and Durability

Measuring just 2.6” x 1.6” x 1.3”, the Liquid Leak Detector’s compact housing is designed for easy placement in various locations, such as basements, near water heaters, under sinks, and around laundry areas. The device is IP-rated to keep liquid out of the housing while detecting the smallest amounts in vulnerable areas.

Fully reusable, the Liquid Leak Detector requires only the replacement of the mylar-coated film strip and the reloading of energy using the magnetic tray. This makes it the perfect set-it-and-forget-it solution, ideal for areas where leaks may occur but where wiring or regular maintenance would be impractical or impossible.

A Future Powered by Innovation

The Liquid Leak Detector doesn’t just offer a technical leap in energy harvesting; it sets a new standard for the performance and reliability of liquid sensing solutions. Its small size, rugged construction, and cutting-edge energy harvesting technology allow for hassle-free, long-term monitoring in any setting.

This innovative device offers the perfect combination of reliability, advanced functionality, and environmental responsibility with a long-term, maintenance-free solution that addresses the growing demand for green, smart sensing systems.

As IoT and smart technologies evolve, WePower Technologies remains at the forefront of innovation. By integrating energy storage, energy harvesting, and advanced wireless communication, we are paving the way for a future of smarter, more sustainable technologies.

Whether you are looking to enhance your sustainability efforts or seeking the most reliable solution for long-term monitoring, the Liquid Leak Detector, powered by Gemns technology, is the answer.
