Micromem Technologies Inc. Receives Approval from the Department of Defence on Wearable Gas Sensing Project Go-Forward Plans
Toronto, Ontario and New York, New York, May 19, 2026 - Micromem Technologies Inc. ("Micromem" or the "Company") (CSE: MRM, OTCQB: MMTIF) is pleased to announce that the Department of National Defence ("DND") has reviewed and approved go-forward plans for the next phase of the Company's gas sensor development program ("the Project"). The Project is part of the existing collaborative research agreement between Micromem, the University of Toronto (the "University"), and the DND ("the Agreement"). This phase of the Project includes enhancing the existing research and development team at the University of Toronto with two new members to focus primarily on the completion of functional wearable prototypes.
This approval validates Micromem's development approach and further strengthens the collaboration with both the University and DND. The representative of the DND under the Agreement has expressed strong support and regular progress meetings will be held between the Company and the representative, with the first meeting anticipated for next week.
The work towards this phase of the Project has commenced and focuses on critical software and hardware development for the wearable gas sensing platform, including sensor integration, signal processing, data acquisition, and system miniaturization. The additional engineering team member contributions will help accelerate the transition from laboratory nanowire technology to robust, low-power, field-deployable wearable systems tailored to meet defense performance requirements while supporting broader commercial applications.
Micromem's proprietary nanowire field-effect transistor gas sensing platform continues to show strong potential for dual-use applications in defense, industrial safety, environmental monitoring, and personal protection.
The Company will provide further updates as the work progresses and as additional technical milestones are achieved.
