Custom Designed Actuators and Transducers
Custom Piezo Actuators
Midé has considerable experience in designing and developing for mass production custom piezoelectric actuators/sensors. Midé has a number of OEM customers for whom we manufacture actuators which have been custom designed for their application. If you currently use a bare piezoelectric actuator in your application and feel that Midé’s patented encapsulation process along with streamlined manufacturing process could benefit you please contact us (products).

Custom Bi-Morph Actuators
Piezo bimorph actuators bend up and down with applied voltage. One piezo layer of the actuator is driven with a positive voltage (with the "poling" direction), causing it to contract along the linear axis, while the other piezo layer is driven with a negative voltage (against the poling direction), causing it to extend along the linear axis. This extension and contraction work together to cause the device to bend in one direction. As the polarity of the voltage is reversed, the device bends in the other direction. The speed of the bending motion is simply a function of applied voltage profile and device construction. Typical piezo bimorphs can operate statically or up to several hundred cycles per second, and custom designs can operate much faster.
The Midé QuickPack bimorph actuator, designed for Analog Output Pressure (AOP) valve, controls a pneumatic pressure output proportional to a voltage input. With a constant air pressure input, the dual actuators control air flow through supply and exhaust nozzles balancing pressure in an enclosed control volume and providing the correct output pressure. A cover plate isolates the two bimorphs into two chambers. When the supply actuator seals the control volume, the exhaust actuator vents and the output is at atmospheric pressure - Figure A. When the supply actuator is open and the exhaust actuator is sealed, the valve provides pressure to the output. Click for more information.
