BioMediTech Research Groups

Sensor Technology and Biomeasurements

Group Leader: Assistant Professor Antti Vehkaoja


About Us

Sensor Technology and Biomeasurements Group (STB) concentrates on the research and development of embedded measurement technology for physiological monitoring and related signal processing and data analysis methods. In addition, we study electronic nose techniques for clinical applications. Emeritus Professor Jukka Lekkala continues his research as a member of our research group.

Research interests and expertise

Our primary research interests include:

  • Wearable physiological monitoring systems
  • Signal processing methods for vitals estimation
  • Assessment of vascular condition
  • Ion mobility spectrometry for tissue classification

Collaboration offer and requests

We wish to offer our knowledge in embedded systems, measurement methods and data analysis to both, industrial and academic collaborators. For further discussions, please contact: antti.vehkaoja(at), mobile: +358 40 7393181
