Adaptive and fault tolerant medical vest for life-critical medical monitoring Conference Paper uri icon


  • In recent years, exciting technological advances have been made in development of flexible electronics. These technologies offer the opportunity to weave computation, communication and storage into the fabric of the every clothing that we wear, therefore, creating intelligent fabric. This paper presents a medical vest which has sensors for physiological readings and software-controlled, electrically-actuated trans-dermal drug delivery elements. Furthermore, computational elements are embedded in the vest for collecting data from sensors, processing them and driving actuation elements. Since this vest will be used for medical, life-critical applications, the single most critical requirement of such a vest is an extremely high level of robustness and fault tolerance. Meantime, the key technological constraint for these mobile systems is their power consumption. Our target application for our medical vest is the detection of possibly fatal heart problems, specifically unstable angina pectoris or ischemia. We illustrate the design stages of our medical vest as well as the technical details of both software and network reconfiguration schemes (to enhance the robustness and the performance of our system). We also discuss the details of ischemia detection algorithm employed in our vest. Moreover, we evaluate the robustness of our system with existence of various faults. Finally we measure the performance of our algorithm as well the power consumption of several configurations of our vest. Copyright 2005 ACM.
