| In the past few years, smartphone makers and application developers have been pioneers in technology, which means that the role of mobile devices in the lives of users has changed.Social media feeds and angry birds are now introducing a variety of fitness And sleep monitoring applications, reimaging the phone as an important health tool as well as a communications device. The latest breakthrough in this area by engineers at UC San Diego will enable people with diabetes to monitor their blood glucose levels while 3D printing is The key part of the development process.  Patrick Mercier, a professor of electrical and computer engineering at the University of California, San Diego, says: "Integrating glucose detection technology into smartphones eliminates the need for patients to carry separate devices." Another benefit is the ability to autonomously store , Process and send blood glucose readings from cell phones to care providers or cloud services. Called the GPhone, this innovative system, currently under proof of concept, was created by a team created by the University of California San Diego's Satisfactory Wearable Sensor Center and details of their projects are presented in an article entitled ' The use of electrochemical glucose sensors integrated into the smartphone platform 'was presented in the paper Biosensors and Bioelectronics. The technology allows people with diabetes to check their blood glucose levels anytime, anywhere, using a few simple components and a proprietary mobile app.The main part is a slim, specially designed smartphone case that uses 3D printing technology Cheap production. This has a united sensor in a corner, is reusable. Some small disposable, enzyme-coated globules magnetically attached to the sensor are housed in a 3D printed stylus attached to the side of the smartphone housing.These particles contain an enzyme called glucose oxidase, which Reaction with glucose The electrical signals generated by this chemical reaction can be measured by the electrodes of the sensor and the higher the signal, the higher the glucose concentration.Tested glucose concentration tests show that the system can measure blood glucose levels with very high accuracy. To test the glucose level, the user activates the ball by dispensing the ball onto the sensor, then the user places their blood sample on top, and the sensor measures the blood glucose concentration as explained, then wirelessly transmits the data via Bluetooth to the custom Designed Android application.The software only need to display the numbers on the screen of a smartphone, which is easy for users to read, and the whole process takes only 20 seconds. The next step in the project will be to test the technique on actual blood samples rather than merely preparing glucose concentrations in advance and minimizing the sample size.At present, prototypes use at least a dozen drops of sample per test, which is more than this usually requires diabetics The fingers needed for DIY monitoring kits are more tingling.To make the system commercially viable, it is also necessary to reduce the price of the particles as they are slightly more expensive than the test strips currently used. If the project is successful, the team hopes to one day be able to integrate this sensing technology directly into mobile devices without the need for a special case, and its use is not limited to patients with diabetes, according to Joseph Wang, professor of nano-engineering Say: 'This system is versatile and can be easily modified to detect other substances for healthcare, environmental and defense applications. "The project was acquired by the National Institutes of Health Biomedical Imaging and Bioengineering Institute stand by. |
