1. 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

4. 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 Select a Physical Sensor Identify the INPUT signal for the sensor Identify the INPUT signal for the sensor Briefly describe how the sensor works Briefly describe how the sensor works Identify the OUTPUT signal for the sensor Identify the OUTPUT signal for the sensor Identify AT LEAST ONE biomedical application for that sensor and explain how it is used 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 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)

7. 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. LAB PRESENTATION RULES AND TIPS
