Resistiivsed
Resistiivsed describes devices or sensors whose output is based on changes in electrical resistance caused by external stimuli. They are used across electronics, instrumentation, and sensing applications. The principle relies on Ohm's law: the resistance of a material or a configuration changes when a stimulus—such as pressure, temperature, light, or mechanical strain—modifies its geometry or conductivity. The electrical signal is typically obtained by creating a voltage divider or by measuring a bridge circuit to determine the change in resistance.
Common types include resistive touchscreens, which consist of two thin, conductive layers separated by a spacer.
Other resistive sensors include thermistors (temperature-dependent resistance), photoresistors (light-dependent resistance), and force-sensing resistors (FSRs) that change
Materials commonly used include carbon-based thick films, metal-oxide films, and conductive polymers. Advantages of resistive devices
