Flexible Piezoelectric Transducers

The Flexible Piezoelectric Transducers Piezoelectric Sensor Vibration Sensor Minisense 100 is a low-cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. The pins are designed for easy installation and are solderable. Horizontal and vertical mounting options are offered as well as a reduced-height version. The active sensor area is shielded for improved RFI/EMI rejection. Rugged, flexible PVDF sensing element withstands high shock overload.

The sensor has excellent linearity and dynamic range and may be used for detecting either continuous vibration or impacts. The mass may be modified to obtain alternative frequency response and sensitivity selection (consult factory).

Specifications

  • Flexible and thin: Flexible piezoelectric transducers are designed to be thin and flexible, allowing them to conform to curved or irregular surfaces. This flexibility enables their use in various applications where rigid transducers are not suitable.
  • Piezoelectric material: These transducers are made of piezoelectric materials, such as polyvinylidene fluoride (PVDF) or lead zirconate titanate (PZT). These materials generate an electric charge when subjected to mechanical stress or vibrations.
  • Broad frequency response: Flexible piezoelectric transducers typically have a broad frequency response range, allowing them to capture a wide range of mechanical vibrations or acoustic signals.

Application

  • Washing Machine Load Imbalance
  • Vehicle Motion Sensor
  • Anti-Theft Devices
  • Vital Signs Monitoring
  • Tamper Detection
  • Impact Sensing
