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.

A position sensor for a linear actuator, comprising:
- a capacitor arrangement having a first capacitor element and a second capacitor element, said second capacitor element being movable relative to said first capacitor element and configured to generate a capacitive signal, said second capacitor element being made of an electrically conductive polymer;
- and
- a data processing device for determining a position of said second capacitor element relative to said first capacitor element based on said capacitive signal.
A method for determining a position of a linear actuator, the method comprising:
- providing a capacitor arrangement with a first capacitor element and a second capacitor element, the second capacitor element being made of an electrically conductive polymer and being movable relative to the first capacitor element;
- generating a capacitive signal with the capacitor arrangement;
- and
- determining a position of the second capacitor element relative to the first capacitor element by a data processing device based on the capacitive signal.
A method of producing a position sensor, the method comprising:
- providing a first capacitor element,
- additively manufacturing a second capacitor element from an electrically conductive polymer,
- arranging the second capacitor element to be movable relative to the first capacitor element in a capacitor arrangement, so that a capacitive signal can be generated by the formed capacitor arrangement, and
- connecting the capacitor arrangement for signal exchange to a data processing device for determining a position of the second capacitor element relative to the first capacitor element based on the capacitive signal.
