Micro-nano operating system/robot is also called nano manipulator, nano manipulator, nano manipulator, etc., which is characterized by micro-nano motion control operation and processing of micro-sized objects. At present, with the rapid development of science and technology, it has a very wide range of application scenarios, such as MEMS, molecular operation, DNA sequencing, trillion capacity memory, etc., all these applications need micro-nano operating system.

Micro-nano operating system/robot requires very high motion control precision, usually composed of microscopic vision, driving, sensing and control, etc. Only with closed-loop coordination between each part can micro-nano level precision operation and control actions be completed. This action includes grabbing, lifting, moving, placing, etc.

operating system based on light microscope, SEM based on scanning electron microscope, SPM based on scanning probe microscope, and many more types of micro-nano operating system. Micro-nano operating systems/robots are also commonly used to observe and understand the operation process with a microscope.

In the micro-nano operating system/robot, there is a very important component, called micro-nano operator. Micro-nano operator is the actuator that carries out the specified action in the micro-nano operating system/robot. This actuator needs to provide micro-nano level motion accuracy.

If you need actuators with micro-nano motion control accuracy, CoreMorrow piezo nanomotion and control system products are naturally the main choice.

CoreMorrow piezo nano-motion and control system is famous for its high precision and fast response speed. It has been widely used in various micro and nano-level operating systems and has broad application prospects in the field of modern science and technology.

Through the parallel coordination of six piezo actuators, the object or sample mounted on the top surface can be adjusted for any pose.

The measured parameters of the moving platform of the H60 Hexapod parallel mechanism are as follows.

The core diameter of an optical fiber is usually very small, always several micrometers, so the operation of aligning two optical fibers requires very high precision, generally be up to micro or nano. Manual operation requires very experienced personnel and is time consuming. The adoption of micro-nano operating system robot can not only ensure the accuracy, but also greatly shorten the docking time, improve the production efficiency, and also maintaining the quality.

CoreMorrow 3D piezo motor and 3D flexible flexural piezo nano-positioning stage can provide optical fiber coarse and fine alignment for micro-nano operating system robots. The coarse adjustment stroke can be selected within 100mm, the fine adjustment stroke can be selected within hundreds of microns, and the precision parameters can be selected. 

The piezo linear actuator uses the stick-slip principle to push the moving threaded rod forward gradually. The step is driven by high precision piezo ceramics, which can ensure the accuracy of each step at nanometer level. The motion effect is shown in the video below.

piezo linear actuator not only has high precision, but also large stroke up to 26mm or more. It can be used for large stroke, high precision probe or manipulator adjustment in nano-manipulation applications. In addition, multiple piezo linear actuator can be used to form a structure to form a probe or manipulator with 6 or more dimensions for nanomotion regulation.

In special cavities such as vacuum, nanomotor control is even more impossible to touch by hand. CoreMorrow can provide a vacuum version of the piezo screw linear actuator, compatible with vacuum environment, to complete the nano operation of single or multi-axis probe, operator and manipulator in vacuum chamber.

Micro-nano operating system robots generally operate under high rate, high resolution monitoring devices, the field of vision is very small. The ability to hold and place tiny objects is required for arbitrary manipulation in such a small field of view. In some cases, adsorption (such as electrostatic force, surface tension, etc.) is used for control, but disengagement is more difficult. Therefore, micro-nano operation clamp is preferred.

CoreMorrow piezo clamp/wire clamp is a very suitable tool for holding and releasing the micron diameter lead wire. It can hold and release the micron diameter gold wire, copper wire, silver wire and so on. It is very suitable for automatic integrated circuit production equipment.

For more flexible operation, CoreMorrow nanopositioning stage can be used to match the probe, and the nano-scale motion of the piezo nanopositioning stage itself can be converted into the nano-scale motion control of the probe through appropriate adaptive connection, so as to obtain the high resolution motion ability.

CoreMorrow can provide you with custom designed nanomanipulation solutions.

In the micro-nano manipulative robot system, there will be visual observation, optical manipulation and other operations, such as atomic and molecular manipulation of objects and other operations, usually need to carry out high-precision focus of light and XYZ multi-dimensional movement control.

The optical Z-axis of nano-scale focusing and fine-tuning can be adjusted by the CoreMorrow piezo objective scanner, and the adjustment resolution can be up to nanometers or even subnanometers.

Basic Parameters of CoreMorrow Piezo Objective Scanner :

For the two-dimensional adjustment of the light, CoreMorrow 2D or 3D piezo scanning stage is a good chioce. It is designed with a center through hole, suitable for transmission light applications, which can carry out multidimensional nano motion with loaded light source or optical elements, to complete the adjustment of the position of the light target.

When penetrating the membrane or injecting drugs into the cell, it is easy to damage the membrane or cell if the operation is not fine. Therefore, piezo actuators with high motion accuracy are usually used to solve the problem.

Through the high-frequency micro-nano vibration of the piezo actuator, the film can be penetrated or perforated, so as to carry out the next drug injection and other operations. The piezo actuator can significantly improve the operation accuracy and success rate, so as to ensure the accuracy and smooth experiment.

CoreMorrow has hundreds of types of piezo actuators, the following are basic parameters from several models.

CoreMorrow has nearly 20 years experience of custom design products, we are looking forward to communicating with you.
