According to French media, researchers say that thanks to add-on devices and applications that turn ubiquitous, small mobile phone screens into medical devices , smartphones are revolutionizing the way diseases are diagnosed and treated.

According to Agence France-Presse reported on February 18th, Schwetak Patel, a professor of engineering at the University of Washington, said: "Look at the camera, flashlight and microphone... they are getting better and better."

He said at the annual meeting of the American Association for the Advancement of Science this week: "In fact, the function of a smartphone is as good as some professional equipment."

Smartphones can already be used as pedometers, as well as calculate calories burned and measure heartbeats.

Mobile phones and tablets can also be used as disease diagnostic tools.

Patel said: "You can use a microphone to diagnose asthma and chronic obstructive pulmonary disease. With these assistive technologies, you can treat chronic diseases with non-invasive clinical tools outside the clinic."

You can also use your phone's camera and flash to diagnose blood diseases, including iron deficiency and hemoglobin deficiency.

Patel said: "Put your finger above the camera flash to know the level of hemoglobin in the blood."

The facts show that the performance of an application called HemaApp is comparable to other non-smartphone devices that measure hemoglobin levels without acupuncture. Researchers are trying to get the US Food and Drug Administration approved to promote the software.

Smartphones can also be used to diagnose osteoporosis, a common bone disease in the elderly.

Just hold the phone, open the appropriate software on your phone, and tap the elbows.

Patel said: "The mobile image sensor of the mobile phone receives the resulting resonance. If the bone density decreases, the frequency will change."
