Toronto, Ontario and New York, New York--(Newsfile Corp. - April 6, 2026) - Micromem Technologies Inc. (CSE: MRM) (OTCQB: MMTIF) ("Micromem" or the "Company") is pleased to provide an update on the gas-phase sensor path under its collaborative research agreement with the Department of National Defence (DND) and the University of Toronto (UofT).

The Company's gas phase sensor initiative is focused on the development of highly sensitive detection systems designed for integration into wearable and portable platforms. These systems are being engineered to enable real-time detection capabilities for a range of potential applications, including environmental monitoring, industrial safety, and defense-related use cases.

Recent work conducted in collaboration with the UofT research team has achieved ultra-high sensitivity performance. The Company's sensing platform is being designed to operate at the zeptofarad (10⁻²¹ farads) level, allowing the system to detect extraordinarily tiny electrical changes, so small that they occur when even minute quantities of a substance interact with the sensor. This represents a breakthrough-level sensitivity target for next-generation detection systems.

This level of sensitivity represents a significant advancement beyond conventional measurement approaches and is expected to materially improve the accuracy and resolution of detection systems. The Company believes this capability addresses an unmet need for ultra-precise sensing across a broad range of applications, including advanced technology systems, healthcare diagnostics, energy infrastructure monitoring, and defense-specific use cases.

Micromem is currently advancing a development pathway aimed at delivering gas phase sensing units suitable for wearable applications. This includes ongoing refinement of sensor architecture, signal processing, and system integration to support compact, low-power designs aligned with the requirements of military grade field-deployable systems.

The Company notes that wearable chemical detection systems are an area of active interest within defense and security sectors, including programs focused on enhancing situational awareness and personnel safety. Micromem believes its gas phase sensing technology is well aligned with these emerging requirements and is positioning its development efforts to be responsive to such opportunities, where appropriate.

Micromem's gas phase sensing technology is being developed with a view toward addressing DND demand for real-time, high-sensitivity detection solutions across multiple sectors where rapid and accurate monitoring is critical. The successful development of wearable gas phase sensors represents a significant milestone toward the commercialization of its technology platform. The Company intends to evaluate potential application opportunities and strategic partnerships to advance the technology toward military and commercial deployment.
