Abstract:
A pressure detection device includes a buffer member and a sensor assembly. The buffer member is deformable by a pressure change, and includes a plurality of magnets in an evenly dispersed arrangement. The sensor assembly includes at least one magnetic sensor to detect a variation of a magnetic field accompanied by deformation of the buffer member.
