Pressuresensitive

Pressure-sensitive describes materials or devices whose physical response depends on applied pressure, enabling detection, bonding, or signaling. The term is used in adhesives, sensors, coatings, and paints.

Pressure-sensitive adhesives are viscoelastic materials that briefly bond to a surface under light pressure and remain

In sensing, pressure-sensitive devices convert mechanical pressure into an electrical, optical, or thermal signal. Common mechanisms

Applications span electronics, medical devices, automotive, aerospace, packaging, robotics, and wind-tunnel testing, among others.

Limitations include temperature sensitivity, creep, hysteresis, aging, and the need for calibration. Researchers continue to improve
