ABSTRACT

This report discusses the development of a biomedical sensor that can be knitted into outer and next-to-skin garments for the measurement of human body temperatures. The overall objective is to produce an easy to care garment capable of providing round the clock ambulatory monitoring of a patient in all circumstances. Although the ambulatory monitoring of a patient would require a range of different sensors, however the focus of the proposed research is to develop a knitted temperature sensor (KTS). The KTS would be developed by laying-in a fine metal wire (as sensing element) into the knitted structure. Operating principle of KTS is based on the inherent propensity of metal to exhibit change in electrical resistance as a result of a change in its temperature.
