Researchers at the Wrocław University of Life Sciences have developed an electronically sensor-equipped egg that, like a submarine, can stay at a pre-programmed depth and measure water quality parameters: pH level, salinity, conductivity and turbidity, and oxygen content.
Already patented, the invention originated from research conducted at the university in Wrocław. While working in the water laboratory on the implementation of the PIV measurement technique (for observing the distribution of water velocities in round-bodied dams), the researchers encountered a significant problem – they had no way of knowing the spatial distribution of velocities in the watercourses and hydrotechnical structures under study.
Looking for a solution and using elements left over from previous projects, at essentially no cost, the researchers constructed an intelligent tracer particle for studying the three-dimensional distribution of velocities and selected water parameters, encapsulated in the form of an egg.
