Solid-state sensors work by converting physical parameters, such as pressure, temperature, or light, into changes in electrical resistance.

Thermistors, photodiodes, and piezoelectric sensors are all types of solid-state sensors.

Thermistors are typically made from metal oxides, such as nickel oxide or manganese oxide.

Photodiodes are typically made from semiconductors, such as silicon or gallium arsenide.

Piezoelectric sensors are typically made from piezoelectric materials, such as quartz or lead zirconate titanate.

Thermistors are primarily used for temperature measurement.

Photodiodes are primarily used for light measurement.

Piezoelectric sensors are primarily used for pressure measurement.

Solid-state sensors offer several advantages over traditional sensors, including smaller size, lower cost, and higher accuracy.

The development of solid-state sensors faces several challenges, including material limitations, fabrication challenges, and cost considerations.

Solid-state sensors are finding applications in various fields, including medical devices, automotive sensors, and industrial automation.
