GOLDFISH Detection of Watercourse Contamination in Developing countries using Sensor
Networks – Enlarged
There is an evident need for monitoring pollutants and/or other environmental
conditions in river flows via wireless sensor networks. In a typical wireless sensor
network topography, a series of sensor nodes is to be deployed in the environment, all
wirelessly connected to each other and/or their gateways. The Faculty of Engineering
of the University of Rijeka, Croatia, together with 11 partnering institutions from the
academic and the industrial sectors from Austria, Bolivia, Columbia, Croatia, France,
Poland, Slovakia, Sweden and Vietnam, is working on this particular goal in the frame
of the EU FP7 research project "GOLDFISH - Detection of Watercourse Contamination
in Developing Countries using Sensor Networks - Enlarged". The project is worth about
2.6 million Euros, of which about 150’000 are dedicated to the activities of the
Faculty of Engineering of Rijeka.
In the course of the work on the GOLDFISH project, advanced computing
communication tools have been successfully developed and tested in wireless networks
of innovative self-cleaning bio-chemical sensors. The topography of sensors’ disposition
was optimized. On the other hand, the Faculty of Engineering of Rijeka (RITEH) team
has investigated the possibility to use three different small-scale river flow energy
harvesting principles to power the foreseen sensor nodes: a miniaturized underwater
turbine, a so-called ‘piezoelectric eel’ and a hybrid turbine solution coupled with a
rigid piezoelectric beam. Thorough modelling and calculations were performed to
optimize the design of the foreseen harvesting devices. The first two concepts were
then successfully validated experimentally in laboratory as well as in real river
conditions (Rječina, Croatia). The miniaturized hydro-generator was then inserted into
the wireless sensor node system and its functionality was confirmed (Lievec, Poland). A
suitable energy management electronics was also successfully developed and tested in
real operation. The developed hydro-generator and its energy management
electronics are embedded into the final configuration of the complete wireless system
aimed at tracking pollution in remote watercourses using sensor network technology,
and successfully tested in the Coello river in Colombia.
