BE 3205 - Introduction to Sensors and Actuators

3 lecture hours 2 lab hours 4 credits
Course Description
This course introduces sensor, actuator, and mechatronic principles with emphasis on their biomedical applications. Specific topics covered include general characteristics of sensors and actuators, temperature sensors, magnetic sensors, and actuators (Hall effect sensors, solenoids, mechanical relays, servos, motors), mechanical sensors (speed sensing, strain gauges, accelerometers, and pressure sensors), and acoustic sensors and actuators (microphones, speakers, and ultrasonic sensors and actuators). The interfacing of sensors and actuators are also covered, particularly the theory and applications of field effect transistors (FETs). Practical system integration and control topics are also covered, but sophisticated control theory topics are deferred to later controls-focused courses. Laboratory experiences reinforce basic concepts. (prereq: EE 2725 or EE 2070 , EE 2905 )
