Explanation should include sensors that measure
• physiological signals
• biopotentials
• biochemical signals.
Process/Skill Questions:
• How are biosignals measured?
• What are characteristics of good biosensors? What are the types of biosensors?
• What are the specific challenges associated with measuring biosignals?
• Why is it important to select the correct biosensor? What criteria are used to select the correct biosensor?
• What are biopotentials?
• What biosensors are currently commonly used [in research and healthcare]?
• What limitations might there be with current biosensor technologies/mechanisms?
