| FOR IMMEDIATE RELEASE | October 26, 2026 |
Toronto, Ontario and New York, New York, October 26, 2026 - Micromem Technologies Inc. ("Micromem" or the "Company") (CSE: MRM, OTCQB: MMTIF) is pleased to provide an update on the development of its compact gas-sensing wearable/portable prototype (the 'Technology"), following the Company's news release dated August 6, 2026. The prototype enclosure shown below illustrates a form factor measuring approximately 120 mm × 80 mm × 18 mm (The "Prototype").
Micromem gas-sensing wearable prototype.
Prototype design highlights a compact form factor intended to support continued sensor-system integration and testing The Technology is the result of the current collaboration (the "Project") between Micromem, Canada's Defence Research and Development Canada and the University of Toronto to develop a Biological and Chemical weapons detection technology. The Prototype is the intended commercial version that will, initially, have oil industry and municipal water quality testing uses. The Prototype will form the base technology for wearable military applications currently being developed for the Canadian Department of National Defense (the "DND").
The Project aims to advance the development of a portable, battery-powered gas sensing system incorporating indium arsenide (InAs) nanowire field-effect transistors (FETs). The technology is being designed to detect target gases and volatile organic compounds by measuring changes in electrical conductance as gas molecules interact with the nanowire surfaces. There will be two distinct system configurations developed, a portable and fixed in place technology, both configurations will incorporate overcurrent protection to safeguard the sensitive nanowire devices and wireless or wired data transmission capabilities to enable external data logging and analysis. In addition, a form factor that is waterproof and more rugged to meet requirements for enhanced oil recovery operations will be developed. The Project is intended to advance the technology through continued prototype refinement and validation.
The Technology is focused on integrating the sensing technology, electronics and supporting components into a compact, practical device. Micromem has completed testing of its first printed circuit board (PCB) version and is progressing on a second PCB version that incorporates design improvements.
The Company will provide further updates.
