NTUST and NTU Develop Sensor for Water Quality Monitoring and Sterilization
Teams from National Taiwan University of Science and Technology (NTUST) and National Taiwan University (NTU) collaborated to develop a self-powered water quality monitoring system. This system integrates pollutant detection and water treatment capabilities, using metal nanotubes to generate electricity from water droplet friction for sensing and sterilization. The research team also created a "wireless sensing bottle" for distributed water monitoring.

National Taiwan University of Science and Technology today issued a press release stating that Lin Tsung-hung's team has long been dedicated to the development of smart biomedical materials and self-driven chemical sensors, while Chu Chin's team focuses on metal nanotube array structures and surface treatment capabilities. By integrating the material engineering and biomedical sensing research strengths of both university teams, they have created a self-powered water quality monitoring system with both "pollutant detection" and "water treatment" capabilities.
The NTUST team uses nickel and tungsten composite metal nanotubes as the core. When water droplets roll on the surface of the nanotubes, the contact and separation between the water droplets and the nanotube structure generate triboelectricity. The system collects and converts this electricity into electrical energy, which then drives sensing and sterilization. This technology generates electricity through water droplet movement, not only reducing energy consumption but also providing a more energy-efficient and low-carbon innovative solution for water quality monitoring.
In addition, the sensors developed by the research team can be combined with different detection chips to detect heavy metal ions such as chromium, lead, and mercury, and can also identify common bacteria such as E. coli and Staphylococcus aureus, demonstrating faster and more sensitive monitoring capabilities compared to traditional sensing technologies.
To bring the technology closer to practical applications, the research team integrated sensing, sterilization, and monitoring platform functions into a "wireless sensing bottle" device. Users only need to drip water samples into the device, and the system can complete pollutant sensing and preliminary purification treatment. The data can also be transmitted to an IoT platform to establish a smart water quality monitoring network.
The research team mentioned that this portable system, which does not require an external power source, can provide rapid detection and preliminary treatment at the first instance. It is suitable for distributed water quality monitoring and real-time treatment scenarios, such as river pollution, water source inspection at disaster sites, and real-time sampling of industrial wastewater discharge. In the future, they will strengthen anti-fouling design, surface protection technology, and modular replacement mechanisms to enhance stability and durability. (Editor: Wu Su-jou) 1150407
