Modern technology has played an ever increasing part in society, especially in the last ten years. From entertainment to healthcare and manufacturing, there is no sector that technology has not transformed in some way. Nevertheless, despite many advances, clinical practice for the measurement of electrical potentials as a result of processes from within the human body (i.e. bio-potentials), such as heartbeat rhythm and muscle signals, still takes place through use of 'wet ' electrodes. Active electrodes have been proposed as a viable alternative to wet electrodes, being able to be applied with or without skin preparation and with comparable noise levels. Capacitive electrodes are a specific kind of active electrode that do not require electrical contact with the skin in order to detect bio-potentials, this means that they require no preparation time and are intrinsically safe. The work detailed in this thesis, documents the design and implementation of a variety of active electrode architectures with supporting analogue and digital electronics. Experiments are performed to illustrate the similarity of signals acquired using the developed technologies against traditional wet electrodes. These active electrodes are demonstrated to be able to detect high quality bio-potential signals with or without electrical contact and, through use of a specially designed interface, are able to detect EEG signals usable for Brain Computer Interfacing.
