Kapazitive Berührungssensoren
Capacitive sensing. In electrical engineering, capacitive sensing (sometimes capacitance sensing) is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric different from air. Unlike resistive touch screens, capacitive screens do not use the pressure of your finger to create a change in the flow of electricity. Instead, they work with anything that holds an electrical charge – including human skin.

FAQ
- What are Capacitive Touch Sensors?
- Capacitive touch sensors are electronic devices that detect the presence or touch of a human finger or conductive object by measuring changes in capacitance. They are widely used for user interface applications in electronic devices.
- How do Capacitive Touch Sensors work?
- Capacitive touch sensors work by forming an electrical capacitor between the sensor electrode and the conductive object (such as a finger). When the object touches the sensor surface, it changes the capacitance, which is detected and converted into a digital signal for processing.
- Can Capacitive Touch Sensors work through non-conductive materials?
- Yes, capacitive touch sensors can detect touch through non-conductive materials like glass, plastic, or even gloves, depending on the sensor's design and sensitivity.
- Can Capacitive Touch Sensors be integrated into IoT systems?
- Yes, many capacitive touch sensors can be integrated into Internet of Things (IoT) systems, allowing touch data to be transmitted wirelessly for remote monitoring and control.
