Industry Applications

 

Piezo Motion’s ultrasonic piezo motors are used around the world in various applications and products within biomedicine, optics, semiconductor and nanotechnology as well as industrial electronic and automotive systems just to name a few.

Applications in industrial

 
Piezo Motion products are used in a broad range of industrial equipment applications, including food and pharmaceutical processing, gas and oil pipelines, power reactors, chemical reactors, steam/water pipelines, and vacuum systems.

PIEZOELECTRIC VALVES FOR FLOW CONTROL

Motorized valves are used throughout many of the largest industries such as medical devices, industrial and lab analysis equipment, food and drug, semiconductor, as well as aerospace and automotive. The vast majority of motorized valves rely on conventional EM motors, which can be bulky, slow responding and inefficient.

Piezo Motion has collaborated with a range of customers from different industries to develop customized motorized valve solutions based on Piezo Motion’s piezoelectric technology. The result has been a range of unique valves which have been shown to provide a superior slim-line and efficient design compared to conventional valves used in many applications. Furthermore, the Piezo Motion piezoelectric valves react faster and are more precise, while at the same time they consume zero energy in the hold position.

MINIATURE ROBOTIC SYSTEM FOR MICROMACHINING & PRECISE POSITIONING

Piezo Motion’s novel lightweight piezo motors can be configured to form highly precise miniature nano-positioning and robotic systems. For example, Piezo Motion’s miniature linear piezo motor can be combined together in X-Y-Z configuration to form a unique and highly accurate 3D positioning. Piezo Motion’s rotary motors are easily configurable as precise rotary stages/actuators offering single arcsec resolution and ultrafast response time.

PIEZOELECTRIC ROTARY STAGE
Accurate angular positioning is extremely important in many fields including: optics, photonics, and life sciences labs. Currently all commercial rotary positioning stages fall into one of three main classes depending on motor type: stepper motor, vector motor or DC servo-motor. Piezo Motion’s newly developed precision piezoelectric rotary stage is a unique software-controlled rotary stage incorporating a proprietary direct-drive motor coupling mechanism. The PRS-1 does not use a conventional electromagnetic motor; instead it uses an advanced piezoelectric actuator under direct digital signal processor (DSP) control. The result is a superior rotary stage that eliminates the well known disadvantages of all previous rotary stage technology, while at the same time providing other intrinsic advantages.

Applications in aerospace & defense

 
From piezoelectric motors used in aircraft cabin equipment to miniature robotic systems for use in satellites, Piezo Motion offers a broad range of high-performance products and solutions for high-precision motion control systems in the aerospace and defense markets.

AIRCRAFT VALVES & CABIN EQUIPMENT

Piezoelectric motors can be used as a direct drive, without the need for gearing or an electrical break, making them ideal actuators for various valve types in aerospace and aircraft applications where space and weight limitations are extremely important. In addition the silent operation of a piezoelectric motor makes them perfect for use in environments that require low noise, such as aircraft cabin interiors.

SATELLITE & REMOTE ROBOTICS

Piezoelectric motors are extremely precise and accurate (e.g. capable of nanometer resolutions). This capability makes piezoelectric motors an ideal motion solution for satellite and robotic applications where accurate positioning of tools and sensors is critical.

UNMANNED AERIAL SYSTEMS
Unmanned aerial systems demand precision and low weight. The low-weight design of Piezo Motion’s piezo motors, coupled with their high resolution and direct drive characteristic provides key advantage in these applications.

Applications in medical devices

 
From Imaging to scanning and robotic surgical devices; the applications for piezoelectric motor technology is broad and the technology is key in providing the best care possible.

ROBOTIC SURGERY

To minimize tissue trauma robotic surgery requires very precise movements coupled with great stability. Piezoelectric motors are uniquely suited for such applications. Firstly, they have nanometer level resolution, secondly the self-holding torque (or force) is extremely high often eliminating the need for any break/holding mechanism. At the end effector of the robot compactness is normally critical, Piezo Motion’s miniature rotary piezo motor and linear piezo motor provide a range of useful applications.

SURGICAL TOOLS

Motorized surgical tools including drills, microsaws, dissecting tools and injectors can all benefit from the light weight and compact size of the piezo motor, therefore reducing surgeon fatigue and risk to patient.

MEDICAL SCANNING
Various instruments used in medical scanning (e.g. MRI) are motorized. In order to overcome the strong electromagnetic fields, such motorized devices require heavy lead shielding to protect the motor and or prevent image distortion. Because piezo motors are not effected by EM fields they are uniquely useful for such applications.
LABRATORY AUTOMATION

Motorized surgical tools including drills, microsaws, dissecting tools and injectors can all benefit from the light weight and compact size of the piezo motor, therefore reducing surgeon fatigue and risk to patient.

3-AXIS NANOMANIPULATOR FOR BIOMEDICAL RESEARCH POSITIONING

The NM3D nanomanipulator is an XYZ positioning system used in microscopy, neuroscience, cellular research, electrophysiology. The NM3D works by converting the rotary motion of an advanced piezoelectric motor (fitted onto each axis of the nanomanipulator) into linear motion. A combination of high torque, variable speed and high angular resolution enables the piezoelectric motor to be used in either continuous or stepper mode. These characteristics facilitate a smooth transition, without degradation in intrinsic performance, from an angular step of less than 5 µrad to continuous motion, and a range of angular velocities, from 5 µrad/sec up to 60 rev/min. This translates into a linear resolution of 0.4 nm and a linear range of velocities from 0.5 nm/sec to 500 µm/sec for each axis of the NM3D. Additional benefits of the NM3D design include the elimination of heat dissipation, the use of non-ferrous and nonmagnetic components, ultra-low electrical noise and low supply voltage (12 VDC), which together make the NM3D ideal for very sensitive applications (e.g. delicate electrophysiological recordings).

MEDICAL POSITIONING SYSTEMS

The XYZ nanopositioning system used in stem cell research, IVF and other microscopy based applications. Simple to use, the micropipette is clamped into the universal holder mounted on the side. The clamp accommodates a range of pipette-holder sizes (3 mm to 15 mm) and can also rotate in a vertical plane (90°). It is mounted on a rotary base plate, which enables complete 360° rotation in the horizontal plane. The system is designed to be mounted directly onto the stage of most popular inverted microscopes using a single bracket and standard screws. Control over the Z-axis can also be achieved using the joystick button. This will cause the manipulator to move rapidly within a few seconds to any user-defined ‘Home’ or ‘Work’ position. This feature is ideal in busy labs where multiple routine procedures are conducted throughout the day; allowing the micropipette to be raised from the Work position to the Home position for micropipette changing and then returned back to the Work position with sub-micron positioning accuracy.
