BiomedicineExample of biomedical instrumentation

Cybernetics in Biomedicine is related to Biomedical Engineering, Human Movement Science, Physiology, Dynamic Systems Theory, Instrumentation, Embedded Systems and Control Engineering. It thus overlaps with many of the department's other research fields. Activities in this field represent the application of methods from cybernetics and control engineering to problems that are related to the human body, mainly in a health perspective.

Our research activities include the following areas:

  • Multi-modal Biomedical Instrumentation
  • Model Based Diagnosis, Treatment and Assessment
  • Movement Analysis
  • Biosignal Processing and Classification
  • Rehabilitation Engineering
  • Integration of Artificial and Biological Neural Systems

Applications:

  • Automatic Glucose Control in Diabetes (Artificial Pancreas)
  • Early Diagnosis of Cerebral Palsy
  • Analysis and Diagnosis of Neck Movements
  • Robot-Assisted Motor Rehabilitation
  • Prosthesis Control Systems

 

Brain CyberneticsDrone actuation with motor imagery

To control one's environment through thoughts had been, until recently, in the realm of science fiction or considered to be a remote dream. However, with the technology available today, humans can use the electrical signals from brain activity to interact with, influence, or change their environments. Our research focuses on creating a direct path of communication between the brain and a target in the external world based on EEG systems with optimized number of electrodes for various neuroparadigms. For that purpose, we use experimental and theoretical methods as well as computer simulations, to develop and explore optimization frameworks and AI models based on Electroencephalography (EEG) measurements and translate them into commands for the actuation of devices like drones, games or biometric systems to identify people. In these videos (NRK video, EEG-MI) we show the control of drones resorting to the EEG motor imagery (MI) signals from the scalp. The long- term goal of the research is to contribute with a better understanding of the mechanism involved in direct communication with the brain to advance our ability to interface technology with the human brain.

Research topics

  • Brain Computer Interfaces (BCI) with static and moving electrodes.
  • Design and control of a robotic system with moving electrodes for EEG measurements, FlexEEG
  • Channel optimization of EEG systems to selected neuroparadigms.

  • RGB primary colors neural signature decoding
  • Detection and prediction of Epileptic seizures with minimal EEG channels
  • Automatic sleep stage classification based on minimally invasive EEG.
  • EEG-based lie detector systems
  • Decoding of hand movement intention for Neurofeedback design

 

Ocean and biologyOcean and fish cage

Fish and other seafood represent an abundant and increasingly important source of healthy food for a growing world population. Observing and understanding the dynamics of the oceans as well as managing, harvesting and culturing its resources in sustainable ways require knowledge and smart technological solutions.

Our research on ocean, fisheries and aquaculture systems focuses on how engineering cybernetics and its accompanying enabling technologies such as automatic control, smart sensors and monitoring systems, can be applied to better understand the processes of the sea and enhance the design and operation of marine biological production and harvesting systems. Important topics include systems biology, mathematical modelling of biological processes and production systems, aquaculture process control, biogeochemical modelling, data assimilation, underwater robotics, marine instrumentation and aquatic telemetry.

Applications

  • Modelling and simulation of the physiology, behaviour and growth of fish and plankton
  • Control systems for fish and plankton production processes
  • Specialised instrumentation and sensor solutions for aquaculture systems
  • Smart technologies for ocean observation
  • Acoustic fish telemetry and underwater communication
  • Biogeochemical modelling and data assimilation
