摘要：A pressure sensitive pen is provided. The pressure sensitive pen comprises a

core body, an elastic element, a first magnetic body having one coil formed of at least a

wire wound around, a second magnetic body, a sliding member, a hollow cylindrical body

with an annular element formed therein and an inductance-capacitance type resonant

circuit. The resonant circuit is electrically connected with the first magnetic body having

the coil wound around. When a force is upward applied on the core body, the force is

further applied on the sliding member through the core body such that the sliding

member in conjunction with the second magnetic body move upward and make the

elastic element deformed, and changing a predetermined distance between the first

magnetic body and the second magnetic body, thereby changing an inductance

generated by the coil, and the resonance frequency of the resonant circuit is thus

changed.
