Abstract:
The present disclosure relates to a piezoresistive sensor that improves measurement precision by using a piezoresistive pattern that increases a piezoresistive deformation rate. An embodiment of the present disclosure provides a piezoresistive sensor that may include: a semiconductor substrate, four beams formed as a cross-shape with reference to a central body of the semiconductor substrate, and sixteen piezoresistive patterns formed on a top of the four beams, wherein sixteen piezoresistive patterns are formed as an “X” shape and are disposed on the four beams so as to form four piezoresistive pattern groups.
