The Piezoresistive Effect and Measuring Pressure

  • Patrick Niedenführ
  • February 2019

Today, innovative sensor technologies provide you with the right pressure sensor for every measuring task. Not only can you choose between relative, absolute and differential pressure sensors that work with different reference values, modern pressure sensors also allow you to choose between different measuring principles based on different physical effects. Piezoelectric and piezoresistive effects are mainly used in modern pressure sensors.
