SENSOR APPLICATION LAB

• Dr. Ahmadi
• ECE 1020

George Washington University
2
LAB OBJECTIVES

• For students to take an active role in learning
  about sensors and their applications in
  biomedical engineering
• For students to enhance their research and
  presentation skills

3
SENSORS

• Sensors convert signals of one type of quantity
  such as hydrostatic fluid pressure into an
  equivalent signal of another type of quantity.
• Biomedical sensors take signals representing
  biomedical variables and convert them into what
  is usually an electrical signal

CLASSIFICATION OF BIOMEDICAL SENSORS

• Physical sensors
• Geometric
• Mechanical
• Thermal
• Hydraulic
• Electric
• Optical
• Magnetic

• Chemical sensors
• Gas
• Electrochemical
• Photometric
• Other physical chemical methods
• Bioanalytic

5
LAB RESEARCH ACTIVITY

• Each Group Should
• Select a Physical Sensor
• Identify the INPUT signal for the sensor
• Briefly describe how the sensor works
• Identify the OUTPUT signal for the sensor
• Identify AT LEAST ONE biomedical application for
  that sensor and explain how it is used

6
LAB PRESENTATION

• Based on your research, prepare a 5-slide power
  point presentation that includes
• Name and Picture of Physical Sensor
• Brief Schematic and Explanation of how the sensor
  works
• Input and Output Signal of Sensor
• Biomedical Application(s) of Sensor (pictures and
  explanation)

LAB PRESENTATION RULES AND TIPS

• Groups should introduce their team members to the
  class before the presentation.
• Each group member must contribute to the sensor
  research.
• Each group member must have an oral part in the
  presentation.
• Presentation should be no longer than 5 minutes.
