Introduction of laboratory instruments used to measure physiological events. Stimulation and conduction of electric signals within the mammalian nervous system and other excitable tissues are demonstrated. Fundamental circuit elements and concepts include resistance, capacitance, inductance, op-amps, impedance, voltage, current, power, and frequency, following the content introduced in BME 231. Fundamental analog measurement concepts include adequate bandwidth and amplitude and phase linearity. Integrative design project emphasizes the practical aspects of quantitative physiological measurements. This course is to prepare learners with sufficient physics knowledge and lab skills to pursue the Bioinstrumentation and Imaging Depth Areas. Moreover, students are introduced to programming (using Python) to deepen the understanding of basic concepts and learn basic skills in data processing. SPICE software will be used throughout the course to design/simulate various analog circuits.
Learning Outcomes1Appraise the validity of established bioelectricity hypotheses and circuit models based on quantitative physiological measurements.
2Document procedures, measurements, and subsequent data analysis in clear and cohesive laboratory reports.
3Design an analog bioinstrumentation measurement system meeting prescribed specifications to accurately record a physiological event.
4Design and simulate analog circuits using SPICE.
5Create simple Python code to plot, analyze, and denoise physiological data. Build functions to simulate a simple bioinstrumentation system.
6Recognize ethical and professional responsibilities in engineering situations and make informed judgments, which must consider the impact of engineering solutions in global, economic, environmental, and societal contexts.
