High Temperature Piezoceramics

Chart showing how QorTek's multilayer piezoelectric actuators have more strain at lower temperatures in comparison to the rest of the world's multilayer piezoelectric actuators (including Germany) and the US and UK's single layer piezoelectric actuators.
Chart representing QorTek's high temperature flextensional actuator displacement per voltage. The x-axis show voltage ranging from 30 to 150V. The y-axis shows displacement from 0.78 mils to 3.94 mils. There is a key showing what each of the 7 different colored lines represent on the chart. To the right of these lines is an image of an actuator next to a ruler indicating that the actuator is 4.6 cm long. The chart is titled, "High Temperature Flextensional Actuator."
4 beige high temperature multilayer piezoelectric actuators with black tops side by side on a grey surface. The 3 on the right are 2.5 cm tall. The actuator all the way to the left is 3.5 cm tall. Underneath this image is text that reads, "High Temperature Multilayer Piezoelectric Actuators."
A beige high temperature multilayer piezoelectric actuator next to a ruler on a white surface. The ruler shows that the actuator is 2.4 cm tall. Underneath this image is text that says, "High Temperature Multilayer Piezoelectric Actuator."
Two images side by side showing a high temperature actuator being tested at 300°C. Underneath these images is text saying "QorTek High Temperature Actuator Tested at 300°C"
Chart titled, "Extreme Temperature, High Density Energy Harvesting." The x-axis is temperature ranging from 0 to 400°C. The y-axis shows normalized power density (mW/g^-2cm^-3) ranging from -0.025 to 18.

Most competing piezoelectric ceramics (PZT) are limited to 100-125˚C. However, QorTek high-temperature piezoceramics expand this limit to 300-350˚C and can provide solutions to actuation and sensing/harvesting clients with high temperature requirements in a small form factor that enables new design space in actuator and sensing/harvesting applications.
