You have been asked to review a medical device that will be used to monitor the breathing pattern of premature infants in a Neonatal Intensive Care Unit (NICU). The elastic resistive transducer in the device consists of a thin elastic tube filled with an electrically conductive material. The resistance of the conductor is given byR=rho×(I/A)whererhois the resistivity of the conductor,lis the length, andAis the crosssectional area of the conductor. The elastic tube is wrapped around the infant's chest to monitor breathing. (Adapted from Introduction to Biomedical Engineering,3rd ed. Enderle and Bronzino, 2012) a. Identify two design advantages of this type of transducer. You should think about the characteristics of the device, as well as the characteristics of the measurement. Estimate the response time of this transducer if it is to be capable of measuring a breathing rate of 80 breaths/min. Identify and describe another biomedical sensor that should be used to monitor the oxygen saturation status of premature infants.
