Prinsys team from Aalto Department of Electronics and Nanoengineering proudly presents:
Next-Generation Leak Detection: Wireless, Maintenance-Free, and Built to Last
Introducing the future of leak detection: a wireless, maintenance-free sensor designed to protect any type of building or asset for over 10 years without the need for batteries. Our compact and flexible design allows for easy placement anywhere – under appliances, in basements, pipelines, or roofing.
This advanced sensor delivers real-time alerts to your smart building system or phone, ensuring early detection of leaks without the hassle of complex wiring. It’s simple, reliable, and offers cost-effective leak protection for any space
Team vision
To be the leading technology provider of smart water leak detection solutions, ensuring building durability and high availability with unmatched reliability and advanced technology
Team mission
To design, develop, and deliver decades-long lasting, battery-free, and flexible water leak detection devices for buildings. Our leak detectors are simple to install, providing our customers with peace of mind.
Key features
Durable: Designed for 10+ years of maintenance-free operation.
Effortless: Wireless operation and minimal maintenance.
Easy to install for any type of building.
PrinSys LeakMonitor is a system designed to address the common problem of water leaks in older buildings. The focus of this work is to create a sustainable, flexible, battery-free sensor node that is cost-effective and easy to install. By emphasizing environmentally friendly design, the goal of the LeakMonitor system is to reduce maintenance needs and environmental impacts.
The research involves developing energy-harvesting electrodes that utilize printed electronics sensor technology. A high-performance, energy-efficient sensor circuit on a chip is being developed, targeted at specific applications identified through thorough market research.
The aim of LeakMonitor is to significantly lower the direct and indirect costs associated with water damage. The current market share of leakage detection solutions is limited in older buildings due to high costs and complex installation processes. This system addresses these challenges by providing a more user-friendly and affordable alternative that leverages integrated electronics and flexible, practical semiconductor technology. This innovative approach not only improves efficiency but also supports sustainability goals by eliminating reliance on traditional battery technology.
Interested in Piloting our Hydrodetector?
If you manage a large portfolio of real estate and would like to become a pilot customer for our Hydrodetector leak detection system, please get in touch using the form below. Participation in the pilot program is free of charge, and we are currently seeking user experience references to support further development.
SDG Sustainability Impact
Hydrodetector innovation supports sustainable development by replacing toxic materials and complex manufacturing processes with non-toxic, environmentally friendly alternatives. It leverages simple methods like printing technology to create flexible, cost-effective Hydrodetector sensor nodes for energy harvesting, sensing, and communication.
By eliminating the use of harmful components found in conventional batteries—such as cobalt, nickel, and ammonium chloride—this solution introduces an eco-friendly sodium chloride (NaCl) alternative. Hydrodetector harvests energy directly from fluid leaks, reducing pollution and health risks while promoting sustainable energy use and environmental protection.
The state has high expectations for our team, and we are determined to prove our value!
