Self-Generating Sensors
Sensors & Instrumentation
Thermocouples, piezoelectric elements, and photodiodes — passive transducers that produce their own signal without external excitation.
Learning Objectives
- Apply the Seebeck relation and cold-junction compensation to thermocouples
- Select thermocouple types for temperature range and sensitivity
- Compute charge and voltage from a piezoelectric accelerometer
- Relate photocurrent to optical power through responsivity
