sleep² is the first sleep lab for your home, helping people finally solve their sleep problems quickly and evidence-based.

Life is often hectic and challenging. That is why about a quarter of the population in western countries suffers from poor to very poor sleep quality - with many negative consequences. However, clinical sleep laboratories, which use elaborate measurements to assess sleep, have long waiting lists. In order to make it possible for everyone to have ones sleep analysed at home, Prof. Manuel Schabus, together with mathematicians from the University of Salzburg, has developed a new method of analysing sleep almost as precisely as in the lab. However, their method simply relies on heart activity, which is measured with a simple sensor at night. sleep² additionally offers sleep therapy to improve sleep in the long run.

Dr. Christine Blume

Senior Scientist with focus on sleep and chronobiology (University of Basel & UPK Basel, CH)

Christine is a sleep researcher at the University of Basel and a psychologist in the sleep outpatient clinic of the University Psychiatric Clinics Basel. Already during her PhD, which she obtained at the University of Salzburg in 2016, she discovered the fascination of human sleep for herself. In her current research projects, she is particularly interested in the importance of natural daylight and artificial light for sleep. She is also an active and well-known science communicator on sleep-related topics (e.g. Deutschlandfunk Nova, ORF, SRF).

Collaboration & ​Competence Partners​

As an expert partner in the field of performance marketing, domicom is supporting the project. Effective and efficient campaigns are one of the key success factors for the further development of nukkuaa.

As an expert partner dotsandlines was already supporting sleep² with concept-development, user experience design, screen design, graphic design, corporate identity & branding input. Further development in those aspects will be one of the key success factors.

Polar is an established supplier of ​high quality yet affordable sensors. ​To ensure smooth communication between the sensors and the APP (software updates) as well as to adapt the handling of the sensors to customer needs (local storage of data on the sensors), we work together with Polar ​as a competence partner.

The focus and performance promise ​of the RB Athlete Performance Center ​is performance enhancement for ​selected top athletes. This also includes the optimal utilization of regenerative processes such as healthy sleep. In coordination with the APC, the APP ​offer can be expanded to include an additional target group.

As Scientific Director of the Red Bull Athlete Performance Center, Thomas leads and manages all initiatives around performance optimization at Red Bull. This also includes the optimal utilization of regenerative processes such as healthy sleep.

It is of high scientific interest to ​further accompany and research the classification of sleep phases based on ​AI algorithms, the effectiveness of the digital therapy as well as its individuation also in a scientific framework. The laboratory acts as a cooperation partner for the science-based evaluation and further development of the sleep² product offer.

Through the IP exploitation agreement between PLUS and Nukkuaa GmbH, ​the economic exploitation of scientific know-how is on a legally sound and economically fair footing.

As part of the WISS 2025 research project, "Das Gesundheitshaus" has developed an off-body mattress sensor that accesses the AI algorithms developed in the project and can validly classify sleep phases. As soon as this sensor is ready for market, the plan is to also integrate this sensor into the Nukkuaa APP.

As the Dean of the newly founded faculty, Arne is also guiding the department of “Artificial Intelligence and Human Interfaces”. Arne is supporting the development of sleep² in his role as senior advisor.​

The Lab for Intelligent Data Analytics Salzburg (IDA Lab) funded by Land Salzburg (WISS 2025) serves as central facility for basic and applied research, as well as for knowledge and technology transfer in Data Science, Machine Learning and Statistics & Prof. Borgelt and his team are consulting and actively supporting the further development of AI algorithms to classify sleep stages in sleep².​
