Paineherkkä

Paineherkkä is a Finnish adjective meaning sensitive to pressure, describing a property or response that changes when mechanical pressure is applied. The term is used in engineering, materials science, electronics and physiology to characterize sensors, materials or tissues that react to pressure with changes in electrical, optical or mechanical states.

Etymology and usage notes: the word is a compound of paine (pressure) and herkkä (sensitive). In technical contexts it often prefixes nouns such as paineanturi (pressure sensor) or paineherkkä materiaali to indicate a pressure-dependent behavior.

Applications and contexts: in sensors and electronics, paineherkät components include pressure-sensing elements and input devices that respond differently to varying levels of force, such as pressure-sensitive displays. In materials science, paineherkkiä materials include piezoresistive and piezoelectric substances whose properties change under applied pressure. In physiology, some mechanoreceptors are described as paineherkkiä because they respond to mechanical pressure as part of the sense of touch and proprioception.

Considerations: the degree of sensitivity can depend on temperature, aging and mechanical history, and devices often require calibration and protective design to maintain accuracy and durability.
