ADW to Showcase MEMS Gas Monitoring Solution at SENSOR+TEST 2026 with Acoustic “Fingerprint” Identification Technology for Mixed Gases

From June 9–11, 2026, ADW will present its independently developed MEMS gas monitoring solution at SENSOR+TEST 2026 in Nuremberg, Germany — one of the world’s leading exhibitions for sensor, measurement, and testing technologies. At Booth 1-521, ADW will demonstrate its latest acoustic sensing technology for intelligent gas analysis and mixed-gas identification.

Multi-Dimensional Acoustic Sensing for Gas “Fingerprint” Recognition

Conventional single-frequency gas sensors often struggle to accurately detect and distinguish complex mixed gases. ADW’s innovative solution utilizes an array of MEMS ultrasonic transducers operating at different frequencies to systematically capture the acoustic characteristics of gas samples across multiple frequency bands.

Each gas component exhibits unique acoustic absorption spectra and sound velocity characteristics at specific frequencies. Together, these acoustic parameters form a distinctive gas “fingerprint” database, enabling highly accurate gas identification and composition analysis.

The solution supports precise detection of:

• Natural gas

• Liquefied natural gas (LNG)

• Biomethane

• Hydrogen-blended gas mixtures

• Pure hydrogen
  

Advanced MEMS Manufacturing and Multi-Level Self-Calibration Technology

MEMS Technology and SMT Integration

The transducer array is manufactured using advanced MEMS microfabrication technology combined with SMT surface-mount processes, enabling highly integrated ultrasonic transmission and reception functionality.

Key advantages include:

• Compact structure

• Excellent consistency

• Scalable mass production capability
  

  
  

Multi-Level Self-Calibration Mechanism

The solution incorporates an innovative real-time self-calibration system utilizing MEMS ultrasonic transducers operating at multiple frequencies.

This mechanism effectively compensates for:

• Ambient temperature variations

• Pressure fluctuations

• Device aging effects

As a result, the system maintains high measurement accuracy and long-term operational stability.

Wide Application Coverage for Gas Metering and Industrial Analysis

Thanks to its advanced mixed-gas recognition capability, the MEMS gas monitoring solution is suitable for a broad range of applications:

City Gas Metering

Accurate flow and composition monitoring for natural gas, biomethane, and other utility gases.

Biomethane Monitoring

Real-time gas quality analysis for biogas purification and pipeline injection systems.

Hydrogen Blending Systems
