Technical details and manufacturing context for Transducer Array

Definition
Within a Probe Generator, the Transducer Array serves as the core sensing and signal generation component. It consists of multiple piezoelectric elements arranged in specific patterns (linear, phased, matrix) that work collectively to produce controlled ultrasonic beams for non-destructive testing, medical imaging, or measurement applications. The array enables beam steering, focusing, and scanning capabilities that individual transducers cannot achieve.
Working Principle
Electrical energy is converted to mechanical vibrations (ultrasound) via the piezoelectric effect in each array element. These elements are excited with precise timing delays to create constructive interference patterns, forming directed ultrasonic beams. Returning echoes are converted back to electrical signals for processing.
Common Materials
Piezoelectric ceramic (PZT), Backing material, Acoustic matching layer, Electrode materials
Technical Parameters
  • Element pitch (center-to-center distance between adjacent transducer elements) (mm) Per Request
Components / BOM
  • Piezoelectric Element
    Converts electrical signals to mechanical vibrations and vice versa
    Material: Lead zirconate titanate (PZT) ceramic
  • Electrode
    Provides electrical connection to piezoelectric elements
    Material: Silver or gold plating
  • Acoustic Matching Layer
    Improves acoustic impedance matching between transducer and medium
    Material: Epoxy composite with tungsten powder
  • Backing Block

Engineering Reasoning
0.5-15 MHz frequency, -20°C to +85°C ambient temperature, 0-100 kPa pressure differential
Piezoelectric depolarization at 150°C Curie temperature, acoustic impedance mismatch >5% from 1.5 MRayl baseline, element delamination at 50 MPa shear stress
Design Rationale: Thermal depolarization of PZT-5A piezoelectric material above Curie temperature, acoustic energy reflection due to impedance mismatch exceeding 5%, adhesive failure at epoxy-glass interface under cyclic thermal loading
Risk Mitigation (FMEA)
Trigger Voltage transient exceeding 200% rated 100Vpp excitation
Mode: Piezoelectric element dielectric breakdown
Strategy: TVS diode clamping at 120V with 1ns response time
Trigger Thermal cycling between -40°C and +125°C at 10°C/min gradient
Mode: Acoustic coupling gel viscosity degradation
Strategy: Silicone-based gel with 0.5% thermal expansion coefficient matching
