Aplicações MIDP em aparelhos móveis celulares e monitoramento remoto de bio-sinais: considerações e desenvolvimento de uma solução

Abstract

The telemedicine has improved a lot in the last few years. Innovations like fiberoptic and the cellular network has given important contributions to that. Another source of improvements has been obtained from microelectronics. Smaller devices, as for instance sensors, embedded systems and cell phones have provided the means for thedevelopment of tools that give accuracy, mobility and comfort during medical evaluation proceedings. With this in mind, our work suggest a remote monitoring solution based on the employment of a mobile phone as network interface in the acquisition of signals. To get there, we developed an Java-MIDP application in the mobile phone that supply functions of user interface, receiving of signals, storage of them and, finaly, the sending to a server in the hospital. The sending of data is made by a HTTP connection, triggered by the MIDP application and supported by data cellular network. For debugging of Java sourcecode, simulation and generation of the executable file, we used the tools J2ME Wireless Toolkit,of Sun, e Nokia Developers Suite, of Nokia. The results were pretty satisfactory in the emulations and real execution, done in mobile phone Nokia 6600. Therefore we have an expectation that the employment of mobile phone with Java applications in the medical evaluation activities might be a growing field in next years, for developers, makers and cellular operators.
