Micromem Announces Formal Publishing Of Cement Integrity Sensor Patent

TORONTO and NEW YORK, Nov. 08, 2016 (GLOBE NEWSWIRE) -- Micromem Technologies Inc. ("Micromem") ("the Company") (CSE:MRM) (OTCQX:MMTIF) through its wholly owned subsidiary Micromem Applied Sensor Technologies Inc. (MAST), is pleased to announce the United States Patent & Trademark Office ("USPTO") has formally advised Micromem that they are publishing our patent application US2016/0266086 A1 on 9/15/16 for the Cement Integrity Sensor (the "patented technology").  This is a foundational patent for technology that will significantly change the way management of oil/gas well cement pours are monitored.  Our patented technology will allow fracking pressures to more accurately match the structural integrity of the cement bore and will provide greater visibility as to the integrity and consistency of the cement installation. It is focused on improvement in operational efficiency and enhancement of environmental protection. The patented technology is designed to operate in real time to alert operations of emerging cement integrity issues that, in the past, have led to serious infrastructure failure and ultimately environmental incursions. 

It is also designed and targeted for use in other structures incorporating cement, for example, highways, bridges and buildings. The patented technology is particularly suited for these applications, in that our sensors are incorporated into the cement as part of the routine cement pour, requiring no special operations.

MEMS (Microelectromechanical Systems) and NEMS (Nanoelectromechanical Systems) are incorporated in the technology components, with a targeted manufacturing cost of fractions of a penny in high volumes. The sensors used in the patented technology are designed to be pervasively deployed throughout the cement structure, are passive in nature and respond to electromagnetic queries for feedback in real time. With no need for external power sources the technology is deployable in a multitude of environments.

Micromem, through MAST, has progressed well beyond the patent stage, has developed and is testing sensor prototypes for oil well applications. The current plan is to have a fully tested in-field demonstration of this innovative technology completed in 2017.
