Product Description

Product Description

 

High-intensity focused ultrasound (HIFU) ceramic is widely used in the beauty, weight loss, and medical industries. This year's emerging products such as the ultrasonic knife, Thermage, and UltraShape are representative examples. Compared with traditional beauty products, its advantages are non-invasive, safe, and long-lasting effectiveness.

 

Product Features:
1. Low impedance, low heat generation, and high power.
2. Stable waveform, high consistency of center frequency and resonant frequency.
3. High electromechanical conversion efficiency and low dielectric loss.
4. Uniform inner and outer curvature, strong spatial directivity, and concentrated focus (about 0.5mm).
5. High-frequency ultrasound: 1MHz - 8MHz.
6. Multiple focusing: 10mm - 100mm.
7. High-strength electrodes, co-fired pure silver electrodes.
8. Long service life, over 15,000 high-power pulses and over 10,000 hours of continuous operation at low power.

Piezoelectric ceramic components are made of lead zirconate titanate (PZT) as the core material and polycrystalline piezoelectrics through ceramic powder sintering process, which are polarized to provide electromechanical coupling characteristics. The structure of the components covers single-layer sheets (thickness 0.1-1mm), multi-layer stacks (2-100 layers) and composite cantilever beams, etc. The surface is plated with nickel/gold electrodes to ensure electrical conductivity, and the exterior is encapsulated with epoxy resin or protected by a metal shell to meet the requirements of different protection levels, such as IP67.
The use of positive piezoelectric effect (mechanical stress → electrical signal) and reverse piezoelectric effect (electrical signal → mechanical deformation) to achieve energy conversion. For example, in ultrasonic applications, the electrical signal drives the piezoelectric ceramics to generate high-frequency vibration (20kHz-15MHz) to emit sound waves, and conversely receives the echo through the positive piezoelectric effect into an electrical signal to complete the distance measurement or imaging function.
