The Piezo Chip Actuator consists of multiple ceramic layers and electrode layers stacked and intersected internally, with external electrodes printed on both sides to lead out the internal electrodes. Through precision grinding processes, the height tolerance of each piezoelectric ceramic is controlled to be smaller than 5um. The company has achieved seamless integration from piezoelectric ceramic powder to the finished actuator, and mass production has been implemented. Currently, the products are applied in the fields of nanoscale positioning, precision manufacturing, and dispensing valve technology.

Drive Voltage: YiNGUAN can flexibly customize the maximum drive voltage of the device. The common available options for the maximum drive voltage we provide are 50V, 75V, 100V, 120V, and 150V. Other special maximum drive voltages can also be customized flexibly according to customer requirements.
Output Displacement: The output displacement mainly depends on the length of the device. Monolithic annular actuators offer a maximum displacement range of up to 3.5um.
Operating Frequency: The long-term operating frequency of monolithic actuators depends on factors such as the resonant frequency of the device and the drive voltage. YiNGUAN can flexibly design according to customer requirements. The maximum drive frequency for stacks can reach up to 50kHz.
Dimensions: The inner diameter, outer diameter, and height of the annular stack can be customized flexibly according to customer needs. For the outer diameter, the minimum available size is 3mm, and the maximum is 20mm. For the inner diameter, the minimum available size is mm, and the maximum is 10mm. In terms of height, customization up to 3 mm is supported.
Wiring Harness: A wiring harness can be optionally equipped while meeting the AWG usage standards. The standard length of the harness is 7.5cm of tinned wire, and both the length and orientation of the harness can be customized flexibly according to customer requirements. To facilitate the connection of positive and negative electrode wires, the soldering point position can be selected within the allowable error range of performance variation.
