Paineherkistä

Paineherkistä is a Finnish term that translates to "pressure-sensitive" or "pressure-responsive" in English. It refers to a material or device that exhibits a change in its properties when subjected to external pressure. This change can manifest in various ways, such as a variation in electrical resistance, a shift in optical properties, or a mechanical deformation.

Common applications of pressure-sensitive materials and devices include touchscreens, where they detect the pressure applied by a finger or stylus to register input. They are also utilized in force sensors, load cells, and medical devices like blood pressure monitors. The underlying principle often involves piezoresistivity, where the electrical resistance of a material changes under mechanical stress, or piezoelectricity, where a material generates an electrical charge in response to applied pressure. The specific behavior and design of a paineherkistä system depend heavily on the intended application and the desired sensitivity and range of pressure detection.
