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:

· It provides a new method of health care and skin care for people. It adopts physical therapy and carries out safe and effective health care according to the characteristics of human skin. The shovel head vibrates 25,000 times per second to decompose and derive the dregs and dead skin in the pore. Regular use can shrink pore, tighten skin, fade spots, smooth wrinkles, so that your skin restores health and elasticity, bloom youth and luster. Using low voltage power supply, it is safer and has longer service life. 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)
