DIDZIS LAPSA is a PhD student at the University of Latvia. He has obtained BSc and MSc degrees from Riga Technical University in Electrical Engineering in 2018 and 2019, respectively. Currently, he is a researcher in the Institute of Electronics and Computer Science. His main research topics and interests are electrical engineering, specifically, circuit board design, power consumption in embedded systems, power consumption in sensor nodes, automation, cyber-physical systems, biological signals and bioimpedance measurement-based heart rate and bio-parameter monitoring.

RIMS JANELIUKSTIS holds a PhD degree in Mechanical Engineering, and currently has positions at the Institute of Materials and Structures, Riga Technical University, and at the Institute of Electronics and Computer Science (EDI). Dr. Janeliukstis is interested in vibration-based structural damage identification and learning damage detection algorithms. He has worked with a non-contact scanning laser vibrometer for experimental modal analysis as well as acoustic emission testing of concrete railway sleepers.

Margus Metshein (Senior Member, IEEE) was born in Kuressaare, Estonia, in 1983. He received B.S and M.S degrees in electronics and bionics in 2006 and 2010, respectively, and a Ph.D degree in information and communication technology from Tallinn University of Technology (TUT), Tallinn, Estonia, in 2018. Since 2016, he worked as Early-Stage Researcher and Research Scientist with Thomas Johann Seebeck Department of Electronics of TUT, Tallinn, Estonia. He is the author of more than 30 scientific papers, one book chapter, and two inventions. His research interests cover the field of bioimpedance-based measurement, biomedical signal acquisition, and the interpretation of cardiorespiratory-related volume changes in the human body through electrical measurements. Dr. Metshein was a recipient of the IEEE 12MTC2020 International Instrumentation and Measurement Technology Conference Best Paper Award in 2020.

Leo Seļāvo Ph.D works at the Institute of Electronics and Computer Science and the University of Latvia. Seļāvo completed his M.S. in Computer Science at the University of Latvia and his Ph.D. in Computer Science at the University of Pittsburgh. His focus is on wireless sensor networks and the Internet of Things (WSN/IoT), the enabling technologies for a pervasive and unobtrusive "macroscope", the applications, and the way they change the world and humanity, specifically, sensory data gathering and analysis with applications to sports, entertainment, digital healthcare, and intelligent transportation systems, prototyping platforms and embedded operating systems, directional communication, and effective IoT applications.
