![]() PI is present worldwide with eight subsidiaries, R&D / engineering on 3 continents and total staff of 700+.įor more information on PI please visit: PI USA designs and manufactures piezo products at the company’s US headquarters in Auburn, MA. The company has been ISO 9001 certified since 1994 and provides innovative, high-quality solutions for OEM and research. PI has been developing and manufacturing standard & custom precision products with piezoceramic and electromagnetic drives for 4 decades. PI is a leading manufacturer of precision motion control equipment, piezo systems, piezo motors and actuators for medical engineering, photonics, bio-nano-technology, & semiconductor applications. Specifications of standard bimorph benders are available here. Piezoelectric actuators can come in a variety of form factors, like stacks, bimorph benders or simple discs. Physik Instrumente's electroceramics division manufactures both types and is set up for custom designs even in smaller production runs at a competitive price. Two basic types of piezo actuators are common: bulk / stacked / glued discrete actuators and cofired (multilayer, monolithic) ceramic actuators. There is no friction and wear involved resulting in a device with very high motion resolution and virtually unlimited lifetime. The new bimorph actuators come in a variety of standard and custom shapes, from rectangular stripes to triangles, circular disks with optional aperture etc.Ĭompact versions with only a few millimeters in size can be produced.Ī piezo actuator is a ceramic device that converts electrical energy into mechanical energy or motion with high precision, speed and force. Variety of Different Shapes, Even with Central Aperture Controllers, OEM driver electronics / piezo power supplies are also available. The piezo bimorph actuators can be factory equipped with position feedback sensors for closed-loop operation. Pneumatic valves, fast optical switches, beam deflection, micropositioning acceleration sensors, medical device engineering, semiconductor manufacturing, aerospace, bio-nanotechnology and automotive. Due to the monolithic design they provide excellent mechanical stability, low operating voltage and can be operated at temperatures to 150☌. Response times are in the millisecond range, important for fast switching or scanning applications. They achieve long travel ranges with motion to 2 mm and nanometer resolution. Example Problem 11.1 In a piezoelectric actuator, not all the converted/stored energy k2 from the input electric energy can be. they are monolithic and all layers are produced in one step. Featuring either a 16 mm or 28 mm active free length, these bimorph benders provide. This is useful for applications such as wire bonding, electrical switches, beam deflection, valves, and acceleration sensors. Product Announcement New Piezo Bimorph Actuators are Smaller, Require Lower Voltage, by PI CeramicĪuburn, MA – piezo ceramics specialist PI ceramic offers a new line of co-fired multilayer piezo bimorph actuators.īimorph piezo actuators achieve a mechanical amplification effect by different layers expanding at different rates. Thorlabs Piezoelectric Benders provide a tip deflection whose magnitude and direction is a function of the applied bias voltages.
