Explore below to learn more about Piezo Direct’s custom capabilities as piezo suppliers starting from raw materials to complex custom piezo elements. From medical, to commercial, to aerospace, to piezoelectric energy harvesting, Piezo Direct can help you harness the capabilities of piezoelectric ceramics in increasingly innovative and novelty piezoelectric products. We specialize in exceptional full service customization, service, and support to meet all your piezoceramic performance, shape, and surface finishing requirements for your desired application. Piezo Direct is a trusted piezoelectric crystal manufacturer and partner you can rely on to deliver high quality, complex custom piezo components with extremely competitive pricing. For over 30 years, Piezo Direct has delivered a wide range of custom piezos, including piezoelectric transducers, piezo actuators, piezoelectric sensors, piezo transmitters, and atomizing transducers with full in house engineering and design support from our California headquarters. HASEL actuators do not contain lead or any other substance banned by the RoHS directive, and HASEL actuators are made from very inexpensive materials, making HASEL a good replacement for stacked piezoelectric actuators.Piezo Direct is a global piezo company that specializes in fully custom piezo elements for every industry and application with many successful partnerships with multi-national corporations. DSMs flexure-guided linear piezoelectric actuators and stages are excellent choices for precision motion control and positioning. While HASEL actuators are well suited for applications in search of small linear actuators, they can also be scaled to centimeter-scale or greater making these actuators appropriate for more than just small scale actuation. HASEL technology offers analog (proportional) control and gets much higher actuation strain (10% for contracting designs and 100% for expanding designs) than piezos, making HASEL actuators a better actuation solution for applications requiring 1-10 millimeters of stroke. HASEL actuation technology enables smart, versatile, and compact motion solutions. With HASEL actuation technology, an electrostatic force is applied to a flexible polymer pouch containing a dielectric liquid, prompting a soft structure shape change. One example is HASEL actuators, which have many similarities to piezoelectric actuators, but they also have some marked differences. Stacked piezoelectric actuators are a common actuation solution, but emerging technologies are offering alternatives for small linear actuators. However, since piezoelectric stack actuators contain lead, a substance banned by the RoHS directive in the EU, many of these applications are searching for alternatives. Common applications for piezo actuators include precise positioning devices, electrical switches, micro-pumps, valves for liquids and pneumatic systems, inkjet printers, and anti-vibration devices. Piezoelectric actuators are used in industrial automation, automotive, defense, and more. Even when stacked, piezos can usually only provide less than one millimeter of stroke. However, the common strain ranges of piezos are very limited, usually 0.1% to 0.15% actuation strain. Since piezoelectric actuators produce very small movements, stacking them in modular layers is a way to get more movement. They are cost-effective and used in small packages. They enable better haptic experiences than older technologies like the eccentric rotating mass (ERM) motor. Piezo elements can be layered on top of each other, creating a stacked piezoelectric actuator. Linear resonant actuators (LRA) are currently considered the gold standard in haptic technologies. This element generates bending or linear movement and force. A ceramic that expands or contracts when an electrical charge is applied is called a piezo element.
