Ceramic sensors and actuators utilize the unique properties of ferroelectricity, piezoelectricity, and pyroelectricity to convert electrical energy into mechanical energy and vice versa.

Thermistors are not ceramic sensors. They are semiconductor devices whose resistance changes with temperature.

Piezoelectric ceramic sensors are widely used in ultrasound imaging, accelerometers, pressure sensors, and various other applications due to their ability to convert mechanical energy into electrical signals.

Ceramic actuators offer several advantages over conventional electromagnetic actuators, including faster response time, higher force output, lower power consumption, and compact size.

Automotive sensors typically utilize semiconductor or MEMS technology rather than ceramic actuators.

Ceramic sensors and actuators can be more expensive, fragile, and have a limited temperature range compared to other types of sensors and actuators.

Thermistors are ceramic sensors whose resistance changes with temperature, making them suitable for temperature measurement.

Pyroelectric sensors convert heat into electrical energy, generating a voltage or current proportional to the temperature change.

Silicon carbide (SiC) is not a common material used in ceramic sensors and actuators. It is primarily used in high-power and high-temperature electronics.

Ceramic materials offer several advantages for sensors and actuators, including high sensitivity, wide operating temperature range, chemical inertness, and mechanical robustness.

Pacemakers are not typically made using ceramic sensors. They are electronic devices that regulate the heartbeat.

Ceramic actuators typically have a limited stroke length, which can be a limiting factor in high-power applications requiring large displacements.

Anti-lock braking systems typically utilize hydraulic or electronic components rather than ceramic actuators.

Ceramic sensors and actuators offer several advantages in harsh environments, including high sensitivity, wide operating temperature range, and chemical inertness, making them suitable for applications in extreme conditions.
