Piezoresistive sensor device is based on the piezoresistive effect in a semiconductor material on a substrate of semiconductor material and made by a diffusion resistor. In which the substrate can be measured directly as the sensing element, the diffusion resistance in the substrate connected in a bridge form. When the substrate is deformed by external force, the respective resistance values ??will change, the bridge will have a corresponding unbalanced output. Silicon piezoresistive sensors used for piezoresistive sensor substrate (or membrane) main material for silicon and germanium, silicon sensitive material made of more and more people's attention, especially in measuring pressure and solid-state piezoresistive sensor applications speed the most common. Integrated sensor is produced using standard silicon-based semiconductor integrated circuit process technology. Typically part of the circuit will also be used preliminary processing of the measured signal is also integrated on the same chip. The thin film sensor is by depositing a dielectric substrate (substrate), the film formed on the corresponding sensitive material. When using the mixing process filter sensor type, the same can be part of the circuit fabricated on the substrate. Thick film sensor is the use of a slurry material corresponding sensor selection filter, coated on a substrate made of a ceramic, the substrate is usually made of Al2O3, and then subjected to heat treatment, so that a thick film forming.
