What is the process of eliminating vibration through piezoceramics

The process of vibration cancellation can be achieved through attaching two piezoceramic sheets to the outer surface of the object. They should be close to the point (in a beam) where undesired bending needs to be controlled.The first sheet is used to measure the strain on the surface. The data from a strain sensor is put into a smart box. This gadget controls the power amplifier which consequently drives second sheet.As a result, the mechanically induced movement from second sheet produces vibrations into the structure, which counter the other vibrations.
