## Abstract

The disclosure is and includes at least an apparatus, system and method for manufacturing piezoelectrics. The apparatus, system and method may include at least a first roller and an end roller; a continuous printable substrate roll extending at least from the first roller to the end roller as the first and end roller turn; at least one printer for printing piezoelectric material onto the continuous substrate roll to form a plurality of the piezoelectrics; and an electric field generator that polls the piezoelectric material as the continuous substrate roll is rolled from the first roller to the end roller. The polling electric field generator may comprise a corona field generator.

## Claims

### Claim 1

A system for manufacturing piezoelectrics, comprising:
at least a first roller and an end roller;
a continuously advancing printable substrate roll extending at least from rotating ones of the first roller to the end roller, wherein the substrate is part of the piezoelectrics;
at least one printer adapted to continuously print piezoelectric ink material onto the continuously advancing printable substrate roll to thereby form a plurality of the piezoelectrics;
an electric field generator configured to supply an electric field to the piezoelectric ink material at a first temperature, wherein the electric field generator is configured to poll the piezoelectric material as the continuously advancing substrate roll is rolled from the first roller to the end roller; and
a cooler comprising a low temperature chamber or pseudo-chamber, the cooler being configured to drive the piezoelectric ink material at the first temperature to a second temperature below the first temperature, the cooler being positioned to cool the piezoelectric ink material immediately following the polling via the electric field generation to freeze the polling of the piezoelectric ink material.

### Claim 2 (depends on 1)

The system of claim 1, wherein the polling electric field generator generates a corona field.

### Claim 3 (depends on 1)

The system of claim 1, wherein the plurality of the piezoelectrics which the at least one printer is adapted to print further comprises at least two conductive layers having the piezoelectric ink material therebetween, and at least two dielectric layers printed on the at least two conductive layers.

### Claim 4 (depends on 1)

The system of claim 1, wherein the piezoelectric ink material which the at least one printer is adapted to print comprises an electro active polymer.

### Claim 5 (depends on 4)

The system of claim 4, wherein the polymer comprises polyvinylidene fluoride polymer.

### Claim 6 (depends on 1)

The system of claim 1, wherein the at least one printer comprises at least a piezoelectric ink material printer, at least one dielectric ink material printer, and at least one conductive material printer.

### Claim 7 (depends on 1)

The system of claim 1, wherein the substrate comprises a flexible substrate.

### Claim 8 (depends on 7)

The system of claim 7, wherein the flexible substrate has a thickness in the range of 2 mils to 10 mils.

### Claim 9 (depends on 1)

The system of claim 1, wherein the printed and polled piezoelectrics are configured to be cut from the substrate roll.
