Piezoresistive pressure sensors are among the most widely used types of pressure sensors. These devices gauge pressure through electrical resistance changes detected when mechanical stress is applied to a material. Piezoresistive pressure sensors are robust, simple, and suited for a wide range of applications in many industries. Below is an overview of the top piezoresistive pressure sensor manufacturers in 2023.
