We present in this work, a technique which consists in coding the values of physiological signals using the ASCII (American Standard Code for Information Interchange) code and transmit the texts obtained through SMS (Short Message Service) protols. The SMS texts received by a mobile phone are decoded to restore the physiological signals. Previously, the SMS messaging protocol was useful in telemedicine only to set appointments between patients and doctors, to alert patients when to take medications and to specify the doses of the drugs. Using our technique, biomedical signals of any kind such as ECG, EEG, changes in temperature or blood sugar levels can be transmitted through SMS. In the set of ASCII code, there are several invisible characters and many other characters that are interpreted by the operating systems as instructions. These classes of characters are a priori, serious handicaps for our applications but we developed strategies to overcome such difficulties. Our technique is in the news coming for telemedicine as it enables the transmission of biosignals at very low costs. We have obtained very satisfactory results.
