METHOD FOR CONTROLLING A PIEZOELECTRIC DRIVE UNIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18550657 titled 'METHOD FOR CONTROLLING A PIEZOELECTRIC DRIVE UNIT

Simplified Explanation

The invention relates to a method for controlling a piezoelectric drive unit. A first control signal is applied to a first electrode of the first piezo element of the piezoelectric drive unit. Additionally, a second control signal is applied to a second electrode of the first piezo element of the piezoelectric drive unit. The first control signal is a continuous positive first voltage signal, while the second control signal is a constant second voltage signal. The first control signal is always greater than the second control signal.

• Piezoelectric drive unit control method:

   * Apply first control signal to first electrode of first piezo element
