1. Instrumentation and processing of physiological signals

Dr. Bolic developed signal processing algorithms to remove noise, estimate parameter and classify different features from a number of physiological signals including electrocardiography (ECG), blood pressure, photoplethismography, bioimpedance, breathing and so on.

 

1.1 Blood pressure and ECG signals

There is increasing recognition that the methods used by physicians to measure blood pressure give inconsistent readings, and in a home-care setting, the possibilities for measurement errors are exasperated by the lack of clinical supervision. Dr. Bolic’s current research on blood pressure estimation is focused on developing a mathematical model for arterial and oscillometric blood pressure to use the model to develop more accurate algorithms for blood pressure estimation. The work on blood pressure and ECG resulted in following journal publications:

1.2 Biomedical Radar signal processing

The final goal of this project is to develop a robust system for detection of attempted suicide events in prisons in time to allow for life-saving interventions. This will be done by processing signals extracted from the radars. The objectives of the signal processing algorithms are to reliably estimate breathing and heartbeat signals and then to produce an alarm when significant changes in physiological conditions are observed.

1.3 Speech enhancement

In hearing aids, background noise and cocktail effect need to be removed while preserving naturalness and intelligibility of the processed speech signal. This is very difficult to do using traditional signal processing algorithms. Dr. Bolic’s group developed novel statistical signal processing algorithms called particle  filters  for speech  enhancement  problems with the goal of achieving high intelligibility of enhanced speech.

1.4 Bioimpedance measurements

Bioimpedance data has not been widely used for diagnostic purposes despite of its great potential because the measurements are not reproducible from one session to another. Dr. Bolic proposed a number of new methods for accurate classification of features using bioimpedance data. This should open a whole set of new possibilities for using bioimpedance measurements in diagnostics. This resulted in the following publications:

1.5 Neuromodulation

Dr. Bolic’s current research on stimulation is related to improving transcranial direct current stimulation (tDCS) and personalizing the stimulation based on the feedback information. In addition, he worked on designing a tongue stimulation unit that can be used to control mouse on the computer using tongue for disabled people. The work on electrical stimulation resulted in following publications:

2. RFID, IoT and Wireless sensor networks

Dr. Bolic’s  research is currently focused on the development of new systems for localization and proximity detection of passive RFID tags and wireless charging. His vision is that automated and ubiquitous localization and proximity detection will be of great use in future Internet of Things as well as in every application in which it is important to detect social interactions and proximity among people and objects.
