Noninvasive Blood Glucose Monitor Goes Portable

Article-Noninvasive Blood Glucose Monitor Goes Portable

Two years ago, a Baylor University researcher developed an electromagnetic sensor that provides a noninvasive alternative to reading blood glucose levels. There was just one problem: it was too big to carry. Now, says Randall Jean, associate professor of electrical and computer engineering, he has developed a method that uses a circuit board small enough to make the device portable.

To measure glucose levels, users press a finger against the sensor. The sensor uses electromagnetic waves to measure blood glucose levels in the body. As the energy goes from the sensor through the skin and back to the sensor, the glucose level is measured through the transference of energy.

Jean took daily samples of 31 people over the course of a few months and compared those samples with levels measured by an over-the-counter commercial sensor. He found that the noninvasive sensor is capable of achieving the same or better accuracy than current commercial sensors.

Jean has applied for a provisional patent for his noninvasive glucose monitoring technology. The next step is to conduct further tests on a wider diabetic population.
