3D printed smartphone case that offers blood sugar monitoring on Phone


The GPhone is a new invention for diabetics who can easily determine the amount of blood sugar with a mobile phone in the simplest possible way.

Thanks to the advancements in technology and the development of the smartphone, it has long been no longer necessary to carry a music player, audio recorder, camera, and many other gadgets, all of which are available to users in a small, practical package. With these interpretations, the new invention of the University of California at the University of California, called the protective body of the Java iPhone, provided the ability to determine the level of glucose and analysis of blood by mobile phones, and added another gadget to the smartphones.

This body kit, which is now being made prototype with 3D printing technology, is like other frames mounted on a mobile phone and uses the phone’s battery to function. At the corner of the case, a special sensor is attached to the printed circuit developed by the scientists, and on the other hand there is an adapter for the displacement of the once-retaining plate of the blood sample.

The user must put one of the small plates on the sensor that is equipped with a magnet and put a sample of his blood on the screen. In this arrangement, the glucose in the sample reacts with an enzyme called glucose oxidase, which produces an electrical signal.

The signal transmitted is analyzed by the sensor electrodes, and then the blood glucose measurement data is transmitted to the smartphone via Bluetooth and is available to the user on an Android application developed to analyze the data and display glucose levels.

The user can save the data or send it to his doctor; on the other hand, performing a blood test with a protective film takes only twenty seconds; at the end of the work, the disposable plate is discarded and the sensor Deactivates itself.

The protective film, of course, is still in the early stages of the test, and on the other hand, it’s worth noting that the special plates used to set up the sensor are a bit more expensive than the paper used in conventional blood glucose meters.

Also, for the time being, for diabetes, a diabetic should put 12 drops of blood on the screen, but the inventors of the J iPhone protective case hope that in the near future, this amount will amount to the amount of blood needed for normal tests with special devices This will be reduced, and on the other hand, instead of using a protective frame, this technology will be embedded in the mobile itself.

A paper on the construction of this advanced protective frame has been published in the journal “Biosensors and Bioelectronics”.
