Miniswys is the leader in miniature piezoelectric linear actuator solutions that drive innovation in industrial and scientific applications. Our proprietary ultrasonic micro-motor technology converts piezoelectric energy into precise linear motion, delivering sub-micron positioning accuracy and high-speed performance in a compact form factor. Whether you need to automate a delicate optical alignment or achieve nanometer-scale adjustments in a research setting, our precision linear actuators offer the perfect blend of technical excellence and commercial reliability to power your next breakthrough.
Innovative Ultrasonic Micro-Motor and Actuator Technology
Our actuators are not your standard piezoelectric actuators – they are custom-designed ultrasonic ceramic motors that harness the piezoelectric effect (electricity from mechanical stress) in a novel way. By exciting a tiny piezo element at ultrasonic frequencies, we generate high-frequency vibrations that drive linear motion through friction.
This resonant design yields incredible benefits: bidirectional movement with unlimited stroke, high power density, and low driving voltage in an exceptionally small footprint. Unlike a traditional stepper motor linear actuator, which relies on magnetic coils and lead screws, our piezoelectric actuator has no magnets or electromagnetic interference. The result is a micro linear actuator that operates silently and reliably even in sensitive environments like MRI machines or cleanrooms.
Our Swiss-engineered technology is backed by decades of R&D and a strong patent portfolio (50+ patents worldwide). This know-how allows us to optimize each micro motor for its intended application, using advanced simulation and AI-driven design tools to fine-tune resonance modes and performance. The outcome: a one-of-a-kind piezomotor that offers high precision and efficiency without the trade-offs of conventional actuators.
Key Benefits of Miniswys Linear Piezo Actuators
Miniature actuator Size, Outsized Performance
Our actuators pack a punch despite their tiny size. Each unit has a small footprint but delivers forces ranging from 50 mN up to several newtons, rivaling much larger linear actuators. This makes it easy to integrate into space-constrained equipment and portable instruments as a small linear actuator solution without sacrificing power or force.
Sub-Micron Precision & Control
Achieve motion accuracy well below a micrometer. In open-loop mode, the intrinsic motion increments are ultra-fine; integrating a sensor for closed-loop feedback, the system can reach sub-micron precision positioning. This level of control is ideal for applications like optical alignment, atomic force microscopy stages and semiconductor metrology, where nano-scale movements matter. The low inherent hysteresis of our piezo design means excellent repeatability, and any minor non-linearity can be compensated via closed-loop control algorithms to ensure pinpoint accuracy.
High Piezo Actuator Speed, Fast Response
With an ultrasonic drive operating at frequencies of hundreds kilohertz, our precision linear actuators respond almost instantaneously to input changes. They can attain linear motion speeds on the order of tens of millimeters per second (our demo modules reach ~80 mm/s)
, enabling high-throughput automation tasks. The piezoelectric actuator has virtually no ramp-up time or backlash, so you get smooth, jitter-free motion — crucial for precision scanning and rapid assembly processes.
Unlimited Stroke & Long Travel Life
Unlike traditional piezo stack actuators limited to a few microns of travel, Miniswys ultrasonic motors can achieve unlimited linear stroke. The slider can travel continuously over long distances for positioning or conveyance tasks. In fact, our micro-motors have demonstrated reliable operation over 80 km of cumulative travel in lifespan testing. This means durable performance in 24/7 industrial use, far outlasting other components in the system.
Zero Power Consumption at Hold
Thanks to a self-locking friction mechanism, our actuator can hold its position securely with no power applied at standstill. There’s no need to constantly power a motor to maintain a load, unlike electromagnetic or stepper drives that draw current to hold position. This feature reduces heat and energy usage in your system, improving efficiency. For example, a precision linear stage can be moved into position and then powered down while maintaining micrometer stability – ideal for battery-powered or heat-sensitive applications.
Low Voltage, Energy-Efficient Drive
Our piezo linear actuators achieve motion at just a few volts. They can be driven with voltages as low as 3 V in certain configurations, opening up possibilities for integration into portable and miniature devices using standard electronics. The low-voltage, low-current operation (with no need for high-power magnets or coils) means minimal electromagnetic emissions and simplified driver electronics, which further lowers system cost and power consumption.
No Magnetic Fields
The ultrasonic piezo mechanism requires no magnets or coils, so the actuator itself is non-magnetic. This is a critical advantage for applications like electron microscopes, MRI-compatible equipment, or aerospace sensors where magnetic interference must be avoided. Our miniature linear actuators provide motion in places traditional motors simply cannot operate safely.
Versatile Linear and Rotary Motion
The Miniswys platform is highly versatile – the same core technology can produce linear or rotary motion, giving you flexibility in design. We offer standard linear actuators as well as rotary micro-motor solutions, and we excel at customizing the form factor to fit your product. This means whether you need a tiny linear translator or a micro rotary motor, we can tailor a solution. Every actuator is designed for easy integration, with options to mount, connect, and control it in line with your system requirements.
High Reliability & Cost-Effective Scalability
Industrial customers demand actuators that work consistently. Our engineering ensures batch reliability in production – generous tolerance design and robust materials guarantee that each unit meets performance specs, making it suitable for mass production. The motors use commodity piezo-ceramic elements and simple constructions that benefit from economies of scale. In short, you get cutting-edge performance at a competitive cost, especially at volume. No complex rare-earth magnets or elaborate assemblies are required, which keeps the unit price and supply chain risk low.
Diverse Industrial Applications for linear actuators
Our miniature linear actuators are empowering a wide range of industrial and high-tech applications by providing precise, efficient motion in places never before possible. Here are just a few examples of where Miniswys actuators add value:
Precision Optics & Photonics
From microscope stages to laser alignment systems, our actuators enable micron-level focusing and positioning. They are used in optical autofocus modules (for example, in compact camera systems) to achieve fast lens adjustments with minimal size and power. The zero-power hold is especially useful in optical setups, maintaining alignment without introducing heat or vibration.
Scientific Instruments & Microscopy
In laboratories and advanced R&D, our technology drives breakthroughs. Atomic force microscopy scanners, nanopositioners, and micro-manipulators benefit from the sub-micrometer resolution and quick response of our piezo motors. Researchers can rely on stable, drift-free motion for imaging and probing at the atomic scale, with the confidence that no magnetic fields will disrupt sensitive measurements.
Robotics & Automation Equipment
For manufacturers automating micro-assembly or semiconductor packaging, Miniswys actuators deliver reliable high-speed motion in a tiny package. These micro linear actuators can be embedded in robotic grippers, stages, or precision dispensers, offering smooth linear movement for tasks that demand both accuracy and throughput. Their long travel life (tested to tens of kilometers) means low maintenance even under 24/7 operation, boosting uptime in production environments.
Medical & Biotechnology Devices
The medical sector leverages our precision linear actuator technology for devices like microsurgery tools, drug delivery pumps, and lab-on-chip systems. The actuators’ small size and low power draw make them ideal for portable or implantable devices, while the lack of magnetic components allows safe use near imaging equipment. For example, a handheld microsurgical instrument can incorporate a Miniswys piezo actuator to achieve fine motion without heating or vibration, improving patient outcomes.
Aerospace & Defense Systems
Aerospace engineers integrate our non-magnetic, low-power actuators in satellite mechanisms, avionics, and defense targeting systems. The ability to function in extreme conditions (vacuum, zero gravity, wide temperature ranges) and hold position without power is highly valued. Our technology ensures that critical components can adjust with high precision (such as optical elements in space telescopes or alignment of sensors) and then lock in place securely for long durations without consuming energy.
Precision Mechanics (Watchmaking & Beyond)
Born in the heart of Switzerland’s watchmaking region, Miniswys knows precision. Our collaboration with watch industry innovators led to MicroReg, a revolutionary regulator actuator for timepieces, ushering in new levels of accuracy in mechanical watches.
These are just a few examples of how our micro-actuators open doors to innovation in ultra-fine mechanical systems. From haptic feedback modules in AR/VR gloves to next-gen consumer electronics, the applications are endless wherever miniaturization and accuracy are required.
