Abstract
A position sensor for a linear actuator, a production method for a position sensor, a linear actuator with a position sensor, and a method for determining a position of a linear actuator. The position sensor has a capacitor arrangement and a data processing device. The capacitor arrangement has a first capacitor element and a second capacitor element arranged to be movable relative to the first capacitor element and designed to generate a capacitive signal. A data processing device is configured to determine the position of the second capacitor element relative to the first capacitor element based on the capacitive signal. The second capacitor element is made of an electrically conductive polymer.
