Tomorrow's piezoelectric ceramic actuator and piezoelectric strain sensor

Strain sensors are mainly used to measure the deformation of a structural surface. Usually, during the entire process of applying force, the load-bearing structure of the machine will be subjected to tensile or compressive strains that are greater or smaller than the required force. Strain sensors can indirectly measure dynamic and quasi-static forces, and the relationship between force and strain is sufficiently linear to effectively meet the requirements of accurate measurement and monitoring. When using strain for indirect measurement, the shunt of force can approach 99%, which is much higher than direct measurement. Strain ε is dimensionless, meaning it is a physical quantity without a unit. In the International System of Units, strain ε is used as a relative measure, and its unit is meters per meter (m/m). We use μ ε as the unit of relative strain, with 1 μ ε=1 microstrain=10-6 m/m=1 μ m/m.
Strain sensors can monitor the process of forces, such as welding force.
The sensor is equipped with electronic components and an IEPE interface. The converter type is 10-32ONF.

Cavity tuning

The 1.3GHz superconducting linear accelerator technology is one of the main development directions of international advanced accelerator technology, which is the core technology of hard X-ray light sources (ERL) based on energy recovery linear accelerators, high-energy high current proton accelerators, international linear colliders (ILC), etc.

Adjust the frequency band inside the cavity using the high output and micro displacement of piezoelectric ceramics.

Hardness testing

The larger the outer diameter of the encapsulated ceramic, the greater its maximum output. The maximum output of the encapsulated ceramic with an outer diameter of VS45 can reach 50000N.

Hardness testing mainly utilizes the high output of piezoelectric ceramics to conduct hardness testing on the tested object.

Micro electrical discharge machining

During the process of micro hole machining using micro electrical discharge machining, a lot of debris will be generated, which will seriously affect the accuracy and processing speed of electrical discharge machining. Piezoelectric actuators are used in the equipment to effectively remove debris generated during processing by utilizing their micro nano displacement, high-frequency vibration, and high output characteristics, playing an excellent role in chip guidance.

cell penetration

The size of cells is generally only a few micrometers, or even smaller. In studying cell structure or pathological experiments, it is necessary to accurately deliver probes into the interior of cells. Piezoelectric actuators can achieve precise nanoscale movement, driving probes or sample cells to perform nanoscale micro movements, accurately delivering probes into the interior of cells without damaging cell structures. They have been widely used in fields such as biotechnology and life sciences.

Shock absorption and suppression

Vibration is something that needs to be avoided or eliminated in many mechanical systems, such as the aerospace and automotive industries.

When vibration is detected in the vibration monitoring system, an electrical signal is applied to the piezoelectric actuator to cause displacement in the opposite direction of the vibration, thereby canceling out the vibration.
