Multilayer Piezoelectric Actuators
AHB Series Metal Sealed 85°C, High Performance
Overview
Multilayer piezoelectric actuators are ceramic elements
used to convert electrical energy into mechanical energy
such as displacement or force by utilizing the piezoelectric
longitudinal effect.
KEMET’s multilayer piezoelectric actuators are produced
based on our unique element structure design and
piezoelectric ceramic materials with high electrostrictive
factors. Compared to conventional piezoelectric
actuators, they are smaller in size but can generate higher
displacements and forces at low voltages.
The AHB Metal Sealed 85°C High Perfomance series
actuators are less impacted by ambient humidity
due to insulation from the atmosphere. As a result,
long operational life and high performance have been
attained which are ideal for use in various high reliability
applications such as semiconductor device production
equipment and optical communication equipment.
Applications

Reliability
Themajorityoffailuremodesonmultilayerpiezoelectricactuatorsareshort-circuitsduetodegradedinsulation.Although
thecauseofdegradationofinsulationhasnotbeenclarified,ithasbeenfoundthatthefailureratevariesgreatlybetween
staticuses(DCvoltageapplication)anddynamicuses(pulsevoltageapplication).Likeotherelectricalcomponents,
piezoelectric actuators can be affected by humidity as well as applied voltage and ambient temperature. KEMET has added
the metal sealed piezoelectric actuators featuring high reliability by eliminating the effects of the ambient atmosphere.
This section describes reliability guidelines for static and dynamic usage of the metal sealed type actuators. Reliability of
ourmultilayerpiezoelectricactuatorsisrepresentedbyMTTF(meantimetofailure)incaseofstaticusage.Thenumberof
repetitions is considered to represent the reliability in the case of dynamic usage.
DC Voltage Application
MTTFr of the metal sealed type under the actual operating conditions is calculated from the reference MTTFs and the
acceleration factor as it is in the case of the resin coated type. However, since the internal element is sealed from the
atmosphere,itisnotaffectedbytheatmospherichumidity.Therefore,equation(1)belowisused.
(1)MTTFr=MTTFs×Av×At
MTTFr : Estimated value
MTTFs:Referencevalue(=36,000hours)
Av: Acceleration factor for drive voltage = (100/VR)2 VR:Actualvoltage(V)
At: Acceleration factor for ambient temperature = 1.5(85-Tr)/10 TRActualambienttemperature(°C)
The following calculation is made for the case of use at 25°C and 150 V.
MTTFr=36,000×(100/150)2×1.5(85-25)
=36,000×0.44×11.3
≈179,000hours(20.4years)

Fixing Method
• Carefully prevent the piezoelectric actuators from being bent, twisted or applied tensile force.
Reference: Twisting and Tension Tolerance
Reference Value Remarks
Twisting Force 3×10−1 N • m or less For an actuator which generates a force
of800N(compressionresistance).
Tension
50 N or less
• Install the actuator so that the center axis of the generated displacement is aligned with the center axis of the load.
• Epoxy-based adhesives are recommended for bonding. Select adhesives that have high rigidity and allow for medium
thickness so that the generation force and displacement cannot be deteriorated. Also, do not form adhesives on the side
of the actuator.
• Whenthermosettingresinisused,performpolarizingtreatment(seecautionsection)aftertheadhesiveissettled.
• The resin coated type is weak to the tensile force due to its structure and may be broken when tensile forces are applied
onto the device. Using the device in the state that constantly applies compression is effective against any mechanical
damage. The pressure applied to this element should be kept at 20% to 50% of the force generated by this element
(compressionresistance).
• Install the element so that the axis of generated displacement is vertical to the mounting surface.

• In driving applications, it is necessary to take consideration of hysteresis, ringing, creep, and other similar phenomenons.
• For pulse driving, it is also necessary to be aware of self-heat generation, charge/discharge current, and the power
supply’s impedance.

Generated force and load relation:
Static load: Initial position (0V position) is dropped
by spring constant but total displacement has the
same value under static load.
Spring load (Fluctuating load): Displacement
is changed by relation between generated
force and spring constant of actuator.
Static load: No load value change when actuator moves.
Fluctuating load: Load value changes by spring reaction when actuator moves.

Handling Precautions
Precautions to be taken when using multilayer piezoelectric actuators
(Please read these precautions before using our products)
1.Beforeusingordesigningasystemusingourproducts,readtheprecautionsandspecificationslistedbelow.
2. The main failures with multilayer piezeoelectric actuators are deterioration of insulation resistance, short-circuit, and
open-circuit.
Before using the products, design systems should be designed carefully to ensure redundancy, prevention of the spread of
fire,andpreventionoffaultyoperationallowingfortheoccurrenceoffailures.
3. Use the products after checking the working conditions and rated performance of each multilayer piezoelectric actuator
series.
SelectionofAEseries(resincoatedtype)orASB,ASLorAHBSeries(metalsealedtype)shouldbebasedontheintended
working temperature and humidity.
• Connecttheredleadwiretothepositive(+)terminalofthepower
supply.
• Avoid electric shocks since a high voltage is in use.
• Never apply excessive tension to a lead wire.
• Do not handle the product by picking up or moving the lead wire.
• Machining of the actuator element and replacement of the lead wire are
prohibited.
• Donothandletheresincoatedtype(AEseries)withbarehands.
• Donotwashtheresincoatedtype(AEseries)withorganicsolvents.
• Avoid excessive physical shock. Otherwise, the internal piezoelectric
ceramic element may be damaged.
• If the actuator is exposed to high temperatures above 100°C or if used
afterlongstorageperiods(morethanthreemonths),thedeviceshould
bepolarizedbyusingthecircuitconfigurationandconditionsshownatright.
• Do not apply voltage exceeding maximum rating voltage, or rapid charging and discharging.
• Donotusetheactuatorinhighconcentrationsofhighlyinflammablegas.
• Align the center axis of displacement of the actuator with the center axis of the mechanical load.
• When operated, the transient response time of the actuator should be less than 1/3 of the resonant frequency in order to
prevent damage by ringing.
• Storethemetalsealedtypepreferablyinadryatmosphere(desirablybelow40%RH)atordinarytemperatures(-5˚Cto
+40˚C).Avoidcondensationontheproduct’ssurface.
• Store actuators where there is no vibration.
• Handle products properly as industrial waste. When disposing, please contact your local waste disposal service and make
sure the disposal methods meet all legal requirements.

Connect the red lead wire to the positive terminal of the power supply.
Carefully avoid electric shock since a high voltage is in use.
Never apply excessive tension to a lead wire. Do not handle the product by picking up or moving the lead wire.
Do not disassemble the case of the metal sealed type.
Machining of the actuator element and replacement of the lead wire are prohibited.
Do not handle the resin-coated type AE series with bare hands. Otherwise, the reliability of the element
would be degraded.
Do not wash resin-coated type AE series by organic solvant.
Avoid excessive physical shock resulting from, for example, dropping. Otherwise, the internal piezoelectric ceramic
element may be damaged.
If the actuator is exposed to high temperature above 100 or if it is used after long storage period more
than three months, it should be polarized by using the circuit confi guration and conditions shown below.

Do not apply voltage exceeding maximum rating voltage, or do not do rapid charging and discharging.
These might lead to degradation of the reliability or mechanical fracture.
Do not use the actuator in high concentration of highly infl ammable gas. Otherwise, ignition may occur.
Use the actuator so as not to cause bending, twisting or tension. Furthermore, align the center axis of displacement
of the actuator with the center axis of the mechanical load.
Drive the actuator so that the rising speed is more than three times as much as the resonance period in
order to prevent the device from damaging by ringing.
Store the resin-coated type AE series preferably in a dry atmosphere desirably below 40% RH at ordinary
temperatures 5 to 40˚C. Avoid condensation on the product surface.
Store actuators where there is no vibration.
These products must be handled properly as industrial waste. When disposing, please contact your local waste
disposal service.
Piezo actuator is industrial wastes, make sure disposal method under the laws.
