PZT material PZT-5 is belong to "SOFT PZT",   SOFT PZT characters is following:

 

Typical soft PZT characteristics include:

  • Wide range of frequencies in transmit and receive (sub-audible, audible, ultrasonic)
  • High output, low drive material
  • High frequency, fast response time
  • High sensitivity for active or passive use
  • Ability to use with low voltage or high voltage drive circuits
  • Good mechanical and acoustic coupling
  • Wide variety of shapes and sizes that can be customized to meet specific requirements and applications
  • Wide variety of compositions that can be selected to meet specific requirements and applications
  • Quality of each PZT component is ensured by a rigorous testing regimen. Characteristics such as frequency, capacitance, dissipation, coupling, d33 and mechanical properties are measured and verified against our / customer provided specifications.

Typical soft PZT applications include:

·     .         Undersea exploration (sonar, beacons, imaging, current meters)
·         Aerospace (gyroscopes, accelerometers, level sensing)
·         Medical products (Doppler blood flow, oncology therapeutics (high intensity focused ultrasound), imaging, level sensing, intra-operative tools for ophthalmology (phacoemulsification), dental descaling, general surgery, tissue ablation, medication delivery, hearing enhancement, bubble detection)
·         Consumer products (ultrasonic toothbrushes, jewellery cleaners, contact lens cleaners, computer hard drives, touch screen displays, integrated, ultra-thin speakers and cosmetic enhancement)
·         Industrial and Commercial (flow and level sensors, ultrasonic cleaning, ultrasonic welding, intrusion alarms, fabric needle positioning, solder dispensing, machine vibration monitoring, bubble detection, sonochemistry for improved chemical mixing)
·         Telecommunications (optical switching of telecom lines, buzzers and alarms, Haptics feedback, mobile phone cameras)
·         Automotive (power seat controls, reversing/collision avoidance sensors, anti-knock sensors)
·         Scientific research (nano positioning stages and analytical tools, scanning probe microscopy, advanced acoustics)
·         Oil Exploration (flow and level sensors, down hole drill tool monitoring)
