Topics and Competences
Keywords: sensors, algorithms, sensor fusion, biofluid optics, uremic toxins, dialysis, on-line monitoring, spectrophotometry, spectrofluorimetry, signal processing, smart workwear, physical activity monitoring, energy consumption, fatigue monitoring, automatic speech recognition, speech-to-text applications
The main research field of the SensorTechBME team is to develop flexible and novel sensor technologies and algorithms in biomedical engineering applications:
- To estimate dialysis adequacy and quality securing end stage renal disease (ESRD) patients’ care quality. The research is exploring spectrophotometrical and spectrofluorimetrical characteristics-signatures of the biofluids and performing various signal processing and analysis on those signals.
- To develop beyond the state-of-the-art applications incorporated into a smart wearable multi-sensor fusion system for generating valuable data about the workers’ location, locomotion, physical activity, energy consumption and physiological status;
- For speech-to-text usage in healthcare and industry.
Professor Fridolin is a member of the international European Uremic Toxin Work Group (EUTox WG).
- A novel on-line multicomponent miniaturized optical sensor for monitoring removal of uremic toxins in the spent dialysate during hemodialysis was designed and validated in the European multicenter clinical study.
- A new method and device were developed for real-time physical fatigue estimation based on physiological signals and parameters.
