Rapidly intensifying global warming and water pollution calls for more efficient and continuous environmental monitoring methods. Biohybrid systems connect mechatronic components to living organisms and this approach can be used to extract data from the organisms. Compared to conventional monitoring methods, they allow for a broader data collection...

Animal-based sensors have been increasingly applied to many water monitoring systems and ecological studies. One of the staple organisms used as living sensors for such systems is Daphnia. This organism has been extensively studied and, with time, used in many toxicological and pharmaceutical bioassays, often used for exploring the ecology of fresh...

Many aquatic habitats have become vulnerable to rapid and long-term changes induced by industrialism, air pollution, tourism, fishing activities etc. These factors created an urgent need for extensive water monitoring and conservation. By observing the behaviour of lifeforms, we can monitor the state of the environment. Here, we present the methodo...

Through the combination of artificial components and living organisms, we can develop a novel methodology for aquatic monitoring. By observing the responses of organisms to changes in their environment, a broad-spectrum sensor was created. One of the organisms broadly used as a biosensor is Daphnia. Its broad distribution and well-studied biology m...

Environmental monitoring should be minimally disruptive to the ecosystems that it is embedded in. Therefore, the project Robocoenosis suggests using biohybrids that blend into ecosystems and use life forms as sensors. However, such a biohybrid has limitations regarding memory—as well as power—capacities, and can only sample a limited number of orga...

In the wake of rapid environmental changes, new, efficient ways of monitoring the environment are needed. Traditional sensors and sampling techniques can give accurate data on a small proportion of the overall abiotic factors. The long processing times often delay the monitoring process, thus making it difficult to detect sudden changes in the wate...

Aquatic monitoring is an essential part of battling the rising ecological crisis. Classical methods involving extensive sampling and sensor measurements are precise, however, time and money consuming. For these reasons, they are unsuitable for long-term continuous data collection. With the increasing water pollution, there is a need to monitor the...

The original version of the Chapter “The Use of Robots in Aquatic Biomonitoring with Special Focus on Biohybrid Entities” was previously published as non-open access. It has now been changed to Open Access under the CC BY 4.0 license and the copyright holder updated to ‘The Author(s)’. The book and the chapter have been updated with this change.

Facing the threat of rapidly worsening water quality, there is an urgent need to develop novel approaches of monitoring its global supplies and early detection of environmental fluctuations. Global warming, urban growth and other factors have threatened not only the freshwater supply but also the well-being of many species inhabiting it. Traditiona...

In the wake of climate change and water quality crisis, it is crucial to find novel ways to extensively monitor the environment and to detect ecological changes early. Biomonitoring has been found to be an effective way of observing the aggregate effect of environmental fluctuations. In this paper, we outline the development of biohybrids which wil...
