摘要：
A load arm for a disk drive may include a base section that has an opening for receiving a spindle of a voice coil motor. The base section may have hinge arms that extend from the base section and terminate in tab portions. An arm section may be affixed to the tabs of the hinge arms of the base section such as by spot welding. A head suspension assembly may be affixed to a distal end of the arm section such as by spot welding. A sensor may be provided on a hinge arm of the base section. The sensor may comprise a piezoelectric polymer sensing element and an electrode formed over the piezoelectric polymer sensing element.
