Multilayer Piezoelectric Actuators
AE Series Resin Coated
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 displacement and force at low voltages.
The Resin Coated AE series actuators feature compact size
and a wide variety of shapes for applications such as ultra-fine
positioning mechanism and drive sources.
Benefits
• Large generated force of 3,500 N/cm2
• High-speed response: Driving up to about 1/3 of self-resonant
frequency (in several ten kHz)
• Low power consumption: Can be retained at the leakage
current state of 100 μA or less
• Very small size: 1/10 or smaller than conventional multilayer
actuators
Applications
Typical applications include positioning, auto focusing of optical systems, pumps, mass-flow valves, vibration source, vibration controls,
sensors, image stabilization of DSC, mirror/prism positioning, manipulators, motors and printers.

Multilayer Piezoelectric Actuators – AE Series Resin Coated
Reliability
The majority of failure modes on multilayer piezoelectric actuators are short-circuits due to degraded insulation. Although the cause of
degradation of insulation has not been clarified, it has been found that the failure rate varies greatly between static uses (DC voltage
application) and dynamic uses (pulse voltage application). Like other electrical components, 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 resin coated type actuators. Reliability of our multilayer
piezoelectric actuators is represented by MTTF (mean time to failure) in case of static usage.
DC Voltage Application
The acceleration factors have been obtained empirically for each of the drive voltage, ambient temperature and relative humidity based
on many experimental results. The MTTFr in actual applications is estimated using equation (1) below with MTTFs observed under
accelerated conditions as the reference value.
(1) MTTFr = MTTFs × Av × Ah × At
MTTFr : Estimated value
MTTFs : Reference value (= 500 hours)
Av: Acceleration factor for drive voltage = (150/VR)3.2VR: Actual voltage (V)
Ah: Acceleration factor for relative humidity = (90/HR)4.9HR: Actual relative humidity (RH%)
TR Actual ambient temperature (ºC)
At: Acceleration factor for ambient temperature = 1.5(40 -Tr)/10
The following calculation is made for the case of use at 25°C, 60% RH and 100 V.
MTTFr = 500 X (150/100)3.2 X (90/60)4.9 X 1.5(40-25)/10
= 500 X 3.66 X 7.29 X 1.84
≈ 24,500 hours (2.8 years)
Pulse Voltage Application
In driving dynamic applications, temperature rises as a result of self-heating allowing the component not to be affected by the humidity,
thus extending the operational lifetime. This phenomenon is explained as a result of the humidity factor elimination caused by the selfheating.
Since the self-heating value is affected by multiple factors such as the element’s shape, pulse waveform and frequency, it is difficult to
estimate the actual rising value. Therefore, the life of the actuator cannot be determined by using an equation, unlike the case of DC
voltage applications.
When testing the AE0203D08DF part, there was no failure confirmed after 500 hours end of the pulse driving test. (500 Hz, 0 – 150 V
rectangular pulse).
Users should be careful about the influence of physical damage which can be caused by the fixing method of the element and/or the
driving conditions.

1. Safety designs allowing for failures of electronic components used in the system. In general, failures will occur in electronic
components at a certain probability. KEMET makes every effort to improve the quality and reliability of electronic component
products. However, it is impossible to completely eliminate the probability of failures. Therefore, when using KEMET’s electronic
component products, systems should be carefully designed to ensure the prevention of faulty operation and redundancy in the
event of an accident which would result in injury or death, fire, or social damage. Please refer to Precautions when using multilayer
piezoelectric actuators for more details of failures.
2. Quality level of various kinds of parts and equipment in which the parts can be utilized as electronic components have a standard
quality level unless otherwise specified. KEMET classifies the level of quality of electronic component products into three levels:
a standard quality level, a special quality level, and a custom quality level in which a customer individually specifies a quality
assurance program. Each of the quality levels has recommended applications. If a user wants to use the electronic parts having a
standard quality level in applications other than the applications specified for the standard quality level, they should always consult
26 Multilayer Piezoelectric Actuators Vol.08
a KEMET representative before using the electronic parts.

Precautions cont’d
Standard Quality Level: Computers, office automation equipment, communication equipment, measuring instruments, AV
equipment, household electrical appliances, machine tools, personal equipment and industrial robots.
Special Quality Level: Transportation equipment (automobiles, railways, shipping), traffic signals, disaster prevention/crime
prevention systems, a variety of safety devices and medical equipment which are not directly intended for life-support purposes.
Custom Quality Level: Equipment for airplanes, aerospace equipment, nuclear power control systems, medical equipment
and apparatus or systems for life-support purposes.
Unless otherwise specified, the quality level of KEMET’s electronic component products shown in documents such as catalogs,
datasheets or technical books are the standard quality level.
3. This manual is subject to change without notice. The content of this manual is based on data which is correct as of December,
2014 and they may be changed without notice. If our products are used for mass-production design, please consult with a member
of our company’s sales staff.
4. Reprinting and copying of this manual without prior written permission from KEMET Electronics Corporation is not permitted.

foreign exchange regulations), the sender must obtain an export license from the Japanese Government before said products can
be exported outside Japan.
Precautions to be taken when using Multilayer Piezoelectric Actuators
(Please read these precautions before using our products)
1. Before using or designing a system using our products, read the precautions and specifications (such as level of quality) for the
products you intend to use.
2. The main failures with multilayer piezeoelectric actuators are deterioration of insulation resistance, short-circuit, and open-circuit.
Before using the products, design systems carefully to ensure redundancy, prevention of the spread of fire, and prevention of faulty
operation allowing for the occurrence of failures.
3. Use the products after checking the working conditions and rated performance of each multilayer piezoelectric actuator series.
Selection of AE series (resin coated type) or ASB series (metal sealed type) should be based on the intended working temperature
and humidity.
