Abstract
Approaches to a suspension for a hard disk drive include having an adhered one or more piezo actuating device driven by a negative bias driving voltage. The negative bias driving voltage is lower than ground, therefore such voltage inhibits the migration of ions of an electrically conductive adhesive to an electrically conductive flexure layer, and inhibits the degradation of the resistance of an insulating material positioned between the conductive adhesive and the conductive flexure layer.
