A pioneer in the piezo sensors and actuators, PI Ceramic (PIC) is providing a PIC 700 material for ultrasonic transducers.
PIC 700 material
The PIC 700 is a piezoelectric material that is free from lead and is made from bismuth-sodium-titanate (BNT). At present, the company is exploring various technologies for reliable series production of lead-free ceramic products.
The lead-free material is manufactured as a block using pressing technology. The piezoelectric features of the PIC 700 offer a number of benefits. The high coupling factor makes it ideal for ultrasonic transducer application in the MHz range as well as for hydrophone and sonar applications. The highest operating temperature of the piezo material is 200°C.
Piezo materials can convert mechanical energy into electrical energy and vice versa. This property can be harnessed for actuator and sensor applications. Piezo material-based drives allow high-precision positioning jobs.
PI Ceramic offers a wide range of piezoceramic components and materials, shear modules, stack actuators and multilayer piezo actuators. The company’s Special DuraAct transducers can be utilized as actuators and sensors and can even be used for energy harvesting.
