You have been asked to consult Under Armor® in the design of a device for monitoring performance in endurance athletes, e.g marathon runners. The device is expected to measure biopotentials, and it must operate at 3.7V and 0.1 Watt to meet wearable device regulations. A list of 5 device "components" has been handed to you (see below); you are going to express your opinion about each one of them to your client. All of these components are being screened as candidates for inclusion in a device that is capable of monitoring heart rate. For each of the 5 device components described below. Write a critique and justification, in which you answer the following questions: Is inclusion of the component sufficient for the manufacturer’s needs? Why? If it is not suitable, suggest materials, modifications, or components that will suit their needs. a. A silicone membrane that has zero moisture permeability to carry the flexible circuit board and sensor hardware that is attached to the skin. b. Transducers composed of a silver-silver chloride gel electrode. How many should be used? Where do you suggest placement? c. A system-on-chip that contains an instrumentation amplifier for an ECG, operating with a 50 Hz low pass filter, and operates with a 4-bit register. d. A selection of a recording module operating at 1 Hz, 100 Hz or 1000 Hz. Which should be used? e. Lithium polymer batter with 3.7 V, 400mAh. The client notes that there should be an operational lifetime of a minimum of 2 times longer than the expected period of use.
