A group of researchers from Chung-Ang University has developed a device that converts water into electricity, making this element a source of energy that can activate a fire sensor.
The device manages to convert water into electricity
The device uses hydrovoltaic ( HV ) systems to generate electricity through the interaction of nanostructured materials and water molecules . For example, other fire sensors rely on batteries, whereas HV systems get their power directly from water.
Associate Professor and project leader Byungil Hwang explained: “Our hydrovoltaic system can produce microwatts of power, making it ideal for small-scale applications such as fire detectors and health monitoring systems. This system is self-sufficient, requires only a few milliliters of water, and has a fast response time. “.
The study was published in the Chemical Engineering Journal, and describes how the device uses a nanoporous layer integrated with cotton waste and other materials to generate electricity when exposed to visible or infrared light. In addition, the device demonstrated remarkable stability during continuous 28-day testing, with no corrosion or degradation in performance.
According to Professor Hwang, “This is the first demonstration of the use of a hydrovoltaic system in a fire detection application. Our high voltage system has the potential to be a sustainable power source for various sensor systems, including health and environmental monitoring. “.
This innovative development has the potential in fire detection, health monitoring and environmental sensing , demonstrating how sustainable energy technologies can impact practical applications.
