Biography
Martin J Burke obtained the Higher Diploma in Telecommunications and Electronics with distinction from the Dublin Institute of Technology in 1975 and graduated from the Institute of Radio and Electronic Engineers in the Council of Engineering Institute in 1978. After a brief period in industry he took up postgraduate research in biomedical engineering and was awarded the MSc and PhD degrees by Trinity College Dublin in 1983 and 1991 respectively. He joined the academic staff of the Department of Electronic and Electrical Engineering in Trinity College in 1987. He is currently an Associate Professor in this department and has served two terms as Head of Department. His research interests lie in biomedical instrumentation and applications. His current work includes development of a dry-electrode electrocardiogram (ECG) recording system for ambulatory diagnostic purposes as well as precision characterisation and simulation of the ECG signal. He has published in a range of international journals and conference proceedings.

Research Projects
Project title Dry-Electrode ECG Amplifier and Detector
Summary The requirements of an interfacing preamplifier for use in the measurement of the ECG using dry conductive electrodes. The higher input impedance is required in order to prevent phase distortion of the recorded signal and to obtain a reasonably high CMRR to reject common-mode inference. Other second order and parasitic effects are also more difficult to control. Work is in progress to develop an extremely low power preamplifier for use with dry conductive electrodes in ambulatory ECG monitoring using a wearable vest. It will detect signals having an amplitude in the range 100V 10mV with a 3dB bandwidth of 0.05Hz 2kHz and having a CMRR of greater than 80 dB. The amplifier will provide a gain of 40dB with a power consumption of less than 50W when operating from a 3V supply. It is intended that the amplifier be miniaturised to be mounted in the wearable vest also.

Project title ECG Dry-Electrode Vest
Summary The design of a body-fit vest is underway for the purposes of recording the electrocardiogram in mobile subjects with conductive electrodes which do not require a coupling gel. The aim is to incorporate the electrodes into the material of the vest which is body tight so that reasonable contact can be maintained. This has the advantage of allowing long-term continuous monitoring of the ECG which is not possible with conventional adhesive disposable electrodes. Initial results are promising which would indicate that a signal quality is obtainable with the dry electrodes, which is comparable with that provided by conventional electrodes. With suitable post processing a signal of clinical diagnostic quality should be obtainable. Work on the project involves: gaining an accurate understanding of the ionic to electronic charge transfer at the skin-electrode interface; electrical modelling of the skin-electrode-amplifier interface; identifying and reducing sources of noise and interference and determining the best locations for placing the electrodes.

Project title Electrocardiogram(ECG) Characterisation and Synthesis
Summary This project involves the use of wavelet analysis and dynamic time warping analysis in order to characterise the timing relationships of the consistent waves of the ECG signal. A set of equations has been established which describe the variations in the durations of individual components with heart rate. Work is currently in progress to try to use dynamic time warping to find simple mathematical functions which can be used to simulate individual component waves in the overall ECG signal. A programmable ECG signal generator is also under development, which allows signals to be provided at very low voltage levels with precisely controlled amplitude and timing characteristics. This is intended for use in the calibration commissioning, assessment and maintenance of ECG recording equipment to international and European standards.

Project title Analogue ECG Filtering
Summary Work is in progress on the design of low-power active analogue filters for the purposes of band-limiting the recorded ECG signal for pre-processing. The design of the low-pass filter is straightforward as a Bessel-Thompson filter can be used to obtain phase linearity and avoid signal distortion. The high-pass filter design is much more difficult. Current work is centred on the design of a minimal phase active filter which will provide as high a rejection as possible of low frequency interference and baseline drift which is prevalent in dry electrode recording. At the same time the in-band amplitude response must be flat and the group delay as constant as possible. The impulse response requirements as defined for ECG recording equipment by international and European standards must also be met.

Project title Electronic Sphygmomanometer
Summary A prototype pressure monitor has been developed which will act as an electronic replacement for the mercury and aneroid manometers currently used in sphygmomanometers for the measurement of blood pressure. The manometer measures pressure in the range 0-300 mmHg with an accuracy of +1mmHg and is temperature compensated for offset and span variations from -10 to +60 deg C.
