“Imagine a wristwatch-sized device that non-invasively ‘sees’ under the skin surface, and monitors patient glucose levels, allowing diabetics to continuously test their blood sugar accurately throughout the day without the need to prick their fingers,“ said Steven Van Fleet, President of Micromem Applied Sensor Technologies, Inc. (MASTInc), a wholly owned U.S. subsidiary of Micromem Technologies Inc., a Canadian-based company. “The ability to have constant monitoring of key life-values, such as serum glucose or other critical enzymes, hormones and proteins would forever change the way we manage diseases and deliver healthcare.”
MASTInc technology is based on the simple idea that everything in the world exhibits a unique magnetic signature. With the company’s glucose monitoring device, for example, very specific magnetic sensors based on Hall sensor technology could be calibrated to detect specific magnetic moment behaviors at certain frequencies of glucose molecules in the blood, and measure these levels in a known unit volume.
The company’s ultra-sensitive Hall Cross Sensor (HCS) features a Gallium Arsenide (GaAs) substrate that makes it more sensitive to magnetic fields while reducing errors from magnetic interference and noise. The sensors are typically used to produce low power, high sensitive devices such as: hearing aids, cardiac devices, glucose monitoring, oil and mineral detection, computer technology, security and defense applications. Recently, the company’s researchers developed a glucose-monitoring device for the detection of specific elements in the blood. It has the potential to use the sensor in a non-invasive approach to detect fluctuations in blood glucose without the diabetics’ inconvenience of having to puncture their fingers to test blood sugar levels.
