A course from Udemy about Biomedical Engineering I am skipping all pure electronics lecture and jump to biomedical instrumentation and bioelectric signals …
14. Biomedical Instrumentation
Active Transducers
- Magnetic Induction Transducer
- IOP sensor as an example to monitor the movement of the eye.
- Piezoelectric Transducer
- Sonar, acoustic
- Most used and most famous one in medical
- Crystal microphones
- Photovoltaic Transducer
- ion concentration mesaurement, hearbeat sensors from fingers
- Thermoelectric Transducer
- operate based on the Seebeck effect
- voltage is generated because of temperature difference at thermocouple
Passive Transducers
- Resistive
- Strain Gauge
- Capacitive
- measures change in displacement
- touch screens
- weight measurement
- body motion detection
- Inductive
