Multilayer Piezoelectric Actuators AE Series Resin Coated Overview Applications 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. 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. 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 Resin Coated AE series actuators feature compact size and a wide variety of shapes for applications such as ultrafine positioning mechanism and drive sources.

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. 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 x Av x Ah x At MTTFr : Estimated value MTTFs : Reference value (= 500 hours) Av: Acceleration factor for drive voltage = (150/Vr)3.2 Vr: Actual voltage (V) Hr: Actual relative humidity (RH%) Ah: Acceleration factor for relative humidity = (90/Hr)4.9 (40 -Tr)/10 Tr: Actual ambient temperature (C) At: Acceleration factor for ambient temperature = 1.5 The following calculation is made for the case of use at 25C, 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 self-heating. 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.

Reference: Twisting and Tension Tolerance Reference Value Remarks Twisting Force 3 x 10 N * m or less For an actuator which generates a force of 800 N (compression resistance). Tension 50 N or less -1 * 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. * When thermosetting resin is used, perform polarizing treatment (see caution section) after the adhesive is settled. * 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 (compression resistance). * Install the element so that the axis of generated displacement is vertical to the mounting surface. Driving Method * Connect the red lead wire to the positive (+) terminal of the power supply. Also prevent reverse voltage application. * 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.

Machining of the actuator element and replacement of the lead wire V R2 PA are prohibited. Do not handle the resin coated type (AE series) with bare hands. Do not wash the resin coated type (AE series) with organic solvents. Avoid excessive physical shock. Otherwise, the internal piezoelectric ceramic element may be damaged. Protective resistor R11k If the actuator is exposed to high temperatures above 100C or if used Protective resistor R21k after long storage periods (more than three months), the device should Polarizing conditions: DC voltage application 0V1500.2V (to be retained for 10 seconds) 0 be polarized by using the circuit configuration and conditions shown at right. Do not apply voltage exceeding maximum rating voltage, or rapid charging and discharging. Do not apply voltage exceeding maximum rating voltage, o Do not use the actuator in high concentrations of highly inflammable gas. These might lead to degradation of the reliability or mechanic Align the center axis of displacement of the actuator with the center axis of the mechanical load. Do not use the actuator in high concentration of highly inflam When operated, the transient response time of the actuator should less than 1/3 order to Usebe the actuator soof asthe notresonant to causefrequency bending, in twisting or tension. prevent damage by ringing. of the actuator with the center axis of the mechanical load. Store the resin coated type preferably in a dry atmosphere (desirably 40% RH) so at ordinary Drivebelow the actuator that thetemperatures rising speed is more than thre (-5C to +40C). Avoid condensation on the product's surface. order to prevent the device from damaging by ringing.
