Application note
Depending on the exact application and geometry PowerHap actuators can be mounted and operated
in different ways. Some options shall be explained in more detail:
1) Mounting underneath a membrane
PowerHap™
Membrane
Cavity
Back panel
In this case the PowerHap actuator is clamped between a thin, flexible membrane and a rigid back
panel. By applying a voltage, the actuator elongates and consequently deforms the membrane.
In principle the membrane can be out of any material, but it may be necessary to tune the thickness.
While the membrane needs to be as flexible as possible to maximize the haptic feedback felt by the
user, it needs to be also stiff enough to properly clamp the actuator.
In contrast, the back panel has to be as stiff as possible, so that only the membrane is the deformed.
For optimal performance, it is further recommended that the actuator is compressed by a preload of
1 N up to maximum 5 N.
2) Direct mounting to a load
In some applications, for example if haptic feedback shall be applied to a touchscreen, the
deformation of a membrane may be undesirable. In such cases PowerHap actuators can be mounted
directly underneath the load (for example a touchscreen).
By applying a voltage to the actuator, it elongates and therefore moves the load. This movement can
be felt by the user. For a maximal haptic feedback, the rear panel needs to be as heavy as possible.
Otherwise the PowerHap actuator will not only move the load but also the rear panel and therefore a
part of the performance is lost.
In the simplest case it is possible to press the load on the PowerHap actuator (and consequently also
the PowerHap actuator to the rear panel) by using springs. As in case 1 a preload of 1 N up to
maximum 5 N is recommended. To ensure the position of the PowerHap actuator, it can be either
fixed to the rear panel or the load (by e.g. adhesive tape, glue).

3) Multiple actuators
PowerHap actuators are optimized to deliver a strong haptic feedback. For example, a test load with a
mass of 0.1 kg is accelerated with up to 2.5 g. However, for heavier loads the acceleration decreases.
As a consequence for very heavy loads (like displays) the user may only experience a very weak or
even unnoticeable haptic effect. In such cases it is possible to combine multiple actuators.
General Application Notes
Some parts of this publication contain statements about the suitability of our ceramic piezo
components for certain areas of application, including recommendations about incorporation/design-in
of these products into customer applications. The statements are based on our knowledge of typical
requirements made of our devices in the particular areas. We nevertheless expressly point out that
such statements cannot be regarded as binding statements about the suitability of our piezo
components for a particular customer application. As a rule, EPCOS is either unfamiliar with individual
customer applications or less familiar with them than the customers themselves. For these reasons, it
is always incumbent on the customer to check and decide whether the piezo component devices with
the properties described in the product specification are suitable for use in a particular customer
application.
Do not use EPCOS piezo components for purposes not identified in our specifications,
application notes and data sheets.
Ensure the suitability of a piezo component in particular by testing it for reliability during design-in.
Always evaluate a Piezo component under worst-case conditions.
Pay special attention to the reliability of piezo devices intended for use in safety-critical
applications (e.g. medical equipment, automotive, spacecraft, nuclear power plant).
Do not drive the piezo actuator under resonance conditions.
Design notes
Consider de-rating at higher operating temperatures and loads.
In some cases the malfunctioning of passive electronic components or failure before the end of
their service life cannot be completely ruled out in the current state of the art, even if they are
operated as specified. In applications requiring a very high level of operational safety and
especially when the malfunction or failure of a passive electronic component could endanger
human life or health (e.g. in accident prevention, life-saving systems, or automotive battery line
applications such as clamp 30), ensure by suitable design of the application or other measures
(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by
third parties in the event of such a malfunction or failure. Do not use piezo components in safety-
relevant applications.
Specified values only apply to piezo components that have not been subject to prior electrical,
mechanical or thermal damage.
Operation
Use piezo actuator components only within the specified operating temperature range.
Use piezo actuator components only within specified voltage and current ranges.
Piezo actuator components have to be operated in a dry, non-reducing atmosphere which must
