Piezoelectric

Actuators

By combining its piezoelectric materials expertise and multi-layer capacitor production techniques, Morgan Technical Ceramics ElectroCeramics can now offer a range of multi-layer actuators to meet the growing demand for precise, controllable and repeatable displacement devices in the micrometre and submicrometre range.

Piezo Bimorphs

Today you will find Morgan Technical Ceramics ElectroCeramics piezo bimorphs in a host of specialist application areas, including ultrasonic atomizers, transducers, printing technologies, pneumatic valves, textile machinery and many more. All are the result of close co-design and co-development relationships with our customers The bimorphs are available in a range of sizes from 6 to 74mm in length and 1 to 43mm in width, to reflect the variety of applications in which they can be used.

Piezoceramic Composites

Piezoelectric composite materials dramatically improve the performance of ultrasound and sonar transducers used in medical, biometric, military and industrial applications. By fabricating piezoelectric ceramic into precision pillar arrangements with a polymer matrix filler, the composite configuration will outperform a monolithic component constructed solely of the same piezoelectric ceramic

Standard Shapes and Sizes

Extensive materials and engineering expertise allows the Division to produce a wide range of experimental and prototype components in addition to the standard range of products. Our applications engineers are always pleased to assist and advise customers seeking new solutions to problems involving piezoelectric materials.

Standard Plates

Plates are normally cut from an option of three alternative standard sizes, i.e. Iateral dimensions of 40 x 20mm, 50 x 50mm, 89 x 42mm. Still larger sizes up to 150mm lengths can be cut from discs.

Standard Discs

Discs can be manufactured up to 1 50mm diameter with a thickness range from 0.2mm up to 40mm but not in every combination for every material.

Hemispheres & Focal Bowls

Hemispheres are available in two forms:- Unmachined, low cost, hemispheres with mechanical tolerances + 3% or 0.3mm whichever is greater. Fully machined hemispheres and focal bowls to standard, mechanical tolerances.

Standard Tubes

The table gives the range of standard tubes available. In addition we are able to manufacture outside this range and will be pleased to discuss customers' particular requirements.

Standard Rings

Examples of some of our standard rings are listed in the table, but tooling for a much wider range of sizes is also available. The thickness of rings is easily varied.

Electrodes

Fired on silver electrodes are usually applied to all ceramics (except shear plates). Typical silver thickness is 71µm (0,071mm) per electrode which is satisfactory for most applications. Thicker silver coatings can be applied if required. Cold silver electrodes are applied to shear plates and the cold silver cannot be soldered.
