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:
• Vibration & strain sensing
• Passive vibration/strain detection
• Precise actuation

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.

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

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.
