Your next generation bio-logging system

Dulog is a newly developed bio-logging system with the focus on low-weight tags with high functionality. This includes logging proximity data between animals, getting insights about the activity via sensors and much more starting at 0.6 gram per tag. We aim to support you in researching even the lightest species and implement as many features at as little weight as possible.

dulog features

lightweight

lightweight

Ultra light-weight tags starting from 0.6 gram to support even small species.

configurable

configurable

User-configurable to perfectly match your research question. Dulog can be adapted for each task.

scalable

scalable

Small scale deployment with only two tags or deploying networks up to 100 tags - dulog works in small and large scale applications

reusable

reusable

Tags can be reused, just replace or recharge the battery

customizeable

customizeable

Some features are not like you need them? - dulog is highly customizeable and can be tailored to your needs

The dulog tags

The dulog tags

Either fully packed with features or kept as small as possible to allow the use on even the smallest animals. There are multiple versions of the dulog tags available to best suit your needs. Depending on the configuration and the battery that is chosen, the tag can be as light as 0.6 g.
The tags can detect other tags in a range of around 5-10 meters (proximity detection). This can be used to identify social structures in a group of animals or contact between animals and resources like food or roosting sites. The proximity detection can also be used as a simple localization or presence detection in a certain area. Integrated sensors give an insight about the behavior/activity of the animals. To access the recorded data the dulog tags support remote data download. So retrieval of the tags is not necessary. If they are retrieved however, they can simply be reused. Just change or recharge the battery.

The dulog ground infrastructure

The dulog ground infrastructure

In addition to the mobile node (MN) that are attached to the animal, the dulog system includes one or more ground nodes (GN) that allow remote data download from the mobile tags. This can be either one station at a central position or multiple stations spread over a wider area. When tags are in range (depending of the configuration 50-100 m) of the ground node they automatically transfer their data to the ground node. When they are not in range they continue collecting data on their on board memory, meaning you still get insights about the animal no matter if they are close to the ground node or not. These station also can log the presence of tags in range and thus allow some rough localization. Other than one or more ground nodes no further infrastructure is required, so you can set up the system wherever you want.

These ground nodes work together with all kinds of dulog tags. No matter if they collect sensor data, proximity data or both.

Together with you we will work on the perfect system setup for your study.

Dulog tags on animals

Depending on the animal you want to use the system on, there are multiple ways of attaching. Here, the tag glued to the back of a common noctule bat (Nyctalus noctula) is shown, using a small pouch for attachment.

Of course the dulog system also works with animals other than bats. In case you have questions about how to best attach the dulog tag to the animals you research we will assist you in developing a suitable fixation. If your species requires certain functionality or form factors, we gladly adapt the system to the need of the species you are researching.

About dulog

The development of dulog originally started as research project at multiple German universities and research institutes. After more than six years of development, an extensive and multi-functional wireless animal logging network with focus on proximity logging with ultra low-weight tags has been developed.

In 2020, dulog was set up as spin off from the Institute of Electronics Engineering at the University of Erlangen-Nuremberg, Germany to be able to supply researchers outside of the original research group with the system. Apart from bat research, there are also studies conducted on lizards using the previous version of dulog system, which was developed during the university research project. Currently there are already further studies with bats and birds planned using the new dulog system.

Interested?

Right now, the dulog system is not available for direct order yet, as we still work on tweaking the system even more. However, if you are interested, let us know and we will set up a schedule with you to bring the dulog system to you as soon as possible. Also, feel free to let us know any wishes you have for a system like dulog so that we can implement these features on time for your research.

And of course we will continuously support you in using the dulog system.
