Micromem Technologies Introduces High-Sensitivity Nanowire Gas Sensor with Tunable Amplification
for Industrial Safety and Environmental Monitoring
Toronto, Ontario and New York, New York, August 5, 2025 - Micromem Technologies Inc. (CSE: MRM) (OTCQB: MMTIF) ("Micromem" or the "Company") an innovator in advanced sensor technology, announces a major advancement in gas detection with the release of its nanowire-based gas sensor platform, offering a disruptive solution for safety-critical and precision-controlled environments.
The platform employs a proprietary multi-nanowire sensing array capable of detecting trace-level gas concentrations with extreme sensitivity. Notably, the sensor includes an electrical bias control feature that provides tunable amplification-demonstrated at up to 6x-allowing for enhanced detection performance across various gas types and concentration ranges. The sensor platform is fabricated using standard photolithography processes, making it both cost-effective and scalable for high-volume industrial applications.
This technology gives operators a new level of control and accuracy in gas detection. From leak detection to hazardous gas monitoring, this platform brings a new level of safety and reliability to industrial and environmental applications.
Key Advantages of the Micromem Nanowire Gas Sensor:
- High Sensitivity: Demonstrated robust detection of ethanol vapor with a strong, easily measurable response, ideal for volatile organic compound (VOC) monitoring.
- Tunable Amplification: Unique ability to adjust the electrical gate bias, enabling targeted signal amplification and selectivity based on gas type.
- Versatility: Adaptable to detect multiple gases by altering surface functionalization and bias conditions-useful across oil & gas, chemical manufacturing, mining, and clean energy sectors.
- Compact and Scalable: The sensor's solid-state design allows for integration into IoT-enabled smart infrastructure and remote monitoring systems.
The competitive edge of the Company's nanowire sensor, in markets where precision, compliance, and uptime are non-negotiable, is that it adapts.
Strategic Opportunity
The global gas sensor market is projected to exceed $4.5 billion USD by 20281, driven by increased demand for real-time environmental monitoring, worker safety compliance, and emissions control. Micromem's technology offers a differentiated and scalable solution, now entering the commercialization phase.
1Markets and Markets (2023) reported that the global gas sensor market was valued at around $3.3-3.5 billion USD in 2022 and projected a compound annual growth rate (CAGR) of about 5-7%, which would place the market near $4.5-5.0 billion by 2028
Micromem is now advancing this technology, originally developed under a Department of National Defence initiative, as a commercial platform. The Company is actively seeking strategic partners in the energy, industrial, and environmental sectors to pilot and deploy this military-grade sensing solution in high-impact civilian applications.
