Abstract
Example embodiments include an apparatus that has a piezoelectric contact sensor. The piezoelectric contact sensor includes a semiconductor device having a semiconductor material that defines a channel through which current can flow. The piezoelectric contact sensor also includes a piezoelectric element coupled to the semiconductor material. The semiconductor material is configured to modulate the current channel in response to compressive stress waves at the contact sensor. Other example embodiments include an apparatus that has a slider having an air-bearing surface, a write head integral to the slider, and a piezoelectric contact sensor that includes a semiconductor device and a piezoelectric element.
