What is the process of attaching a bender element ?

It clearly relies which technique was used to polarize the two piezoceramic. A wire is connected to the bender’s outer electrodes if in series operation 5A-type, .0075″ thick plates are poled. The polling arrows point in inverse direction. Then the wires are supplied with ±180 volts. One lead is formed during the simultaneous shorting of the two external electrodes in the parallel operation of poled plates. The second lead is formed when a wire is connected to the center metal shim. These leads can be supplied with ±90 volts.
