Piezo Haptic Element, 9×4 mm BPH0904T38MW100 HF

 Piezoelectric ceramics have direct and converse piezoelectric effects. The pressure sense belongs to the direct piezoelectric effect. When an external force is applied to the PZT, the PZT deforms and the internal polarization state changes, thereby generating electric charge and being detected. Vibration sense belongs to the converse piezoelectric effect, that is, when driving voltage is applied to the PZT, and the PZT produces mechanical deformation, thereby causing vibration.

Application: Smart phones, tablets, laptops, steering wheels, touch panels, console panels, control panels, controllers, and screens, any wearable device, tactile gloves, virtual keyboard, mouse, or stylus.
