摘要：
A capacitive pressure sensing element includes a main body, a power supply with a positive electrode and a negative electrode connected to a first electrode and a second electrode mounted on the main body, a first sheet metal electrically connected to the first electrode, a second sheet metal, and a spring element connected between the second electrode and the second sheet metal. When the spring element is uncompressed, the second sheet metal is misaligned relative to the first sheet metal. When the spring element is compressed, the second sheet metal is move towards the first end to a position with a reduced misalignment degree relative to the first sheet metal, thereby the portion of the first sheet metal squarely opposing the second sheet metal is increased to generate an inductive capacitance between the first sheet metal and the second sheet metal. A related stylus is also provided.
