#10 BLOOD GLUCOSE MONITOR

To keep their blood sugar levels as close to normal as possible, diabetics need to monitor the level of glucose in their blood at least once a day.

Current technology to measure glucose in the blood includes the use of a portable testing meter called the blood glucose monitor. Using the device, a finger prick blood sample applied onto a chemical test-strip generates a simple numerical read-out within seconds.

More sophisticated blood glucose monitors in development include a non-invasive glucose breathalyzer device and an implantable real-time glucose sensor that also releases insulin in a responsive manner.
