Abstract:

-Technological advancement in the field of medicine is one of the greatest contributions of mankind’s immense intelligence and ingenuity to human race. One important application of this advancement is the development of sophisticated medical equipment for better and more reliable diagnostics in hospitals and other medical institutions. In line with this, the group intends to design and construct a module that integrates four physiological sensors, specifically for acquiring Electromyogram (EMG), Galvanic Skin Response (GSR), Blood Volume Pulse (BVP) and Respiration signals of the body, which are being used individually in most medical institutions. This paper includes discussions of electronic circuit designs used and procedures employed in integrating the sensors, the acquisition of the physiological signals, interfacing the module with a computer, and processing of digitized signals. The signal generated by each sensor is digitized and then acquired through the computer’s serial and parallel ports, processed and displayed using MATLAB and Visual Basic. Affective Computing – is computing that relates to, arises from, or deliberately influences emotions, Blood Volume Pressure (BVP) – a circulatory function signals produced each time the heart contracts forcing the blood through the peripheral vessels resulting to the engorgement of the vessels, Electromyogram/ Electromyography (EMG) – a special recording technique that detects nerve function and measures the electrical activity generated by muscles, Galvanic Skin Response (GSR) – tiny tension-related change in skin pores such as skin’s resistance and current conduction influenced by the sweat gland activity and skin pore size, Respiration – the process of breathing and can be measured by the contraction and expansion of the chest cavity around the diaphragm.
