MatMeas Shines at the 2026 Advanced Dielectric Materials Conference & Dielectric Physics Seminar

Date: May 15–16, 2026 | Location: Hong Kong Polytechnic University

In May 2026, the highly anticipated Advanced Dielectric Materials Conference & Dielectric Physics Committee Seminar was successfully held in Hong Kong, China. This academic feast gathered top scholars and industry elites in materials science globally. The MatMeas team was invited to attend the conference to explore the latest developments and applications in dielectric physics, piezoelectric ceramics, and cutting-edge sensing technologies.

1. Plenary Opening & Industry Frontiers

The seminar was held at Hong Kong Polytechnic University. Registration began on the afternoon of May 15, and the opening ceremony officially commenced on the morning of May 16 in the GH201 main hall. The academic atmosphere was vibrant, with signboards guiding attendees to various forums:

2. Exploring High-Temperature Piezoelectrics & Accelerometers

During the invited talks on the afternoon of May 16, experts from Shandong Liens Intelligent Technology shared insights on "Application of Different Vibration Modes of High-Temperature Piezoelectric Materials in Accelerometers." The presentation detailed the working principles of piezoelectric accelerometers, showcasing schematic diagrams of shear and compression sensor structures:

Experts emphasized that high-temperature piezoelectric materials are key to overcoming bottleneck issues in high-temperature accelerometers. Core parameters such as piezoelectric constants, dielectric constants, electromechanical coupling coefficients, and the Curie temperature determine sensor sensitivity and long-term stability:

In displaying self-developed piezoelectric materials, the presentation highlighted the performance mechanism of NBT-based piezoelectric ceramics. Doping modification (e.g., Co2O3) effectively promotes domain switching and lowers oxygen vacancy concentration, making it an ideal material for high-temperature accelerometers operating at 500°C:

Based on these advanced high-temperature technologies, compression-type accelerometers have achieved batch application with significant market translation in cutting-edge fields like nuclear power research:

As a professional materials electrical characterization solutions provider, MatMeas's precision measurement instruments offer reliable support for characterizing high-temperature piezoelectric materials, helping enterprises and research institutes accelerate product development.

3. In-Depth Analysis of the "Hardening Effect" in Lead-Free Ferroelectrics

In the morning plenary reports on May 16, expert Shujun Zhang from the City University of Hong Kong delivered a compelling talk on the "Application of Defects in Perovskite Lead-Free Ferroelectric Materials." The report delved into the role of defect dipoles in lead-free ferroelectrics, particularly the microscopic "hardening effect." Detailed analyses of electron paramagnetic resonance (EPR) spectra, X-ray photoelectron spectroscopy (XPS), and differential charge density revealed how doping alters local polarization and charge distribution:

Such pioneering mechanism research demands extremely high weak-signal capture capabilities from test equipment. MatMeas's broadband, high-temperature, and multi-field coupled dielectric/ferroelectric testing systems are the perfect instruments for addressing these complex characterization challenges.

4. Outlook: Deepening International Academic Cooperation

During the committee working reports, a series of future bilateral and multilateral academic activities were announced. These include the China-Japan Ferroelectrics Meeting online in August 2026, the China-Russia Dielectric/Ferroelectric Materials Seminar in St. Petersburg in September, and the Chinese Physical Society Annual Meeting Dielectrics Division in Changsha in October:

By attending this seminar at Hong Kong Polytechnic University, MatMeas has gained the latest research trends in dielectrics and piezoelectric materials, further reinforcing collaboration bridges with domestic and international top-tier research teams. In the future, MatMeas will continue to innovate, upgrading our measurement solutions to safeguard global advanced materials R&D and industrialization!
