ACTUATORS AND SENSORS

FEATURES

DESCRIPTION

• Dual functionality: piezoelectric actuator & sensor

• Robust Polyimide Packaging

Midé’s QuickPack product line takes advantage of a

patented packaging process that allows the normally

brittle piezoelectric ceramic to be encapsulated in

protective polyimide layers. These protective layers

drastically increases the actuator’s robustness, and

usefulness in real world applications.

• Quick Connect/Disconnect Connector

• Hermetically Sealed for Use in Harsh Environments

• Low Profile & highly flexible

• Available in Different Sizes to Suit Application

The packaging process electrically isolates the

piezoelectric ceramic, and allows the device to be

used in otherwise adverse environmental conditions

including submerged applications.

• Extra-Flexible Packs available for application to

curved surfaces (pipes, etc.)

APPLICATIONS

In addition to the standard QuickPack Products, Midé

offers custom piezoelectric device design solutions.

If a custom size is required please contact Midé

Technology Corporation by emailing:

OPERATION

Most QuickPack Transducers operate on the indirect

piezoelectric 3-1 effect. The piezoceramic used in these

packs is poled through the thickness, and expands and

contracts in plane, perpendicular to the applied field.

Through the use of a specially designed inter-digitized

circuit, the QP10ni is able to take advantage of the

stronger direct piezoelectric 3-3 effect. Instead of being

polarized through the thickness, the piezoceramic is

polarized along the length. This method causes the

beam to behave like a stack instead of a bender. This

causes the device to be much more sensitive to strain in

the longitudinal direction than in the transverse direction.

Piezoelectric ceramic is capable of providing a very

precise signal in response to very small amounts of

imposed strain. The same effect is true in reverse; a

finely controlled input signal can produce an efficient

response in the material when the device is used as

an actuator.

Midé’s QuickPack transducers are designed to provide

precise and repeatable actuation or strain induced

measurement in challenging operating environments.

Midé’s QuickPack transducers are suited for use in

harsh environments commonly found in industrial

applications. The QuickPack transducer is not, however,

ideally suited to a specific application. Instead, Midé

has developed a range of QuickPack products intended

to provide a good starting point for your actuation

or sensing needs. In order to maximize the cost

effectiveness of implementing piezoelectric technology

into your application, it may be necessary to investigate

a custom design suited to your specific application.

The standard QuickPack designs have been tailored to

provide a sample of the many possibilities that exist

when using piezoelectric transducers

A critical aspect to consider when using any type of

strain dependent device is the bond layer thickness

between the device and the surface where the

transducer is installed. To maximize the transducer’s

capability to experience the equivalent strain as the

surface it is mounted to, the bond layer thickness must

be minimized. Midé offers a special epoxy which is

capable of adhering QuickPack transducers to a variety

of surfaces while ensuring an extremely thin bond layer.

Bonded Configuration:

A QuickPack Transducer can be mounted directly to a be clamped as possible. Midé prescribes a clamp line

surface. Such a configuration is referred to as a bonded of 0.200” from the edge of the piezoelectric element

configuration. A bonded QuickPack Transducer can be to provide enough area to properly clamp one end of

away from the neutral axis allows the transducer to

achieve much greater tip displacement than a single

layer transducer would.

ε = ∆L/L

The bonded configuration is an excellent choice

for sensing or creating vibrations in a relatively stiff

structure. Transducers in this configuration can be used

to monitor vibrations caused by an outside source,

or by vibrations created in the structure by another

QuickPack Transducer operating as an actuator.

The cantilever configuration is typically employed when

using a QuickPack Transducer as an actuator, although it

could also be effective in using a QuickPack Transducer

to sense low frequency vibrations or fluid or gaseous

flow. Relatively high displacements are possible using

this configuration. A prime example of a QuickPack

Transducer used in a cantilever configuration is the

Piezoelectric Fan.

Note: The QuickPack IDE has different properties in the

longitudinal and traverse directions. In the longitudinal

direction, the actuator takes advantage of the d33 effect,

while transverse direction is excited by the less efficient

d31 effect. Strains in the longitudinal and transverse

directions are out of phase with each other, i.e., when

the length increases, the width decreases, and vice

versa. Because it is directional. the QuickPack IDE

actuator must be oriented properly in order to achieve

desired performance.
