Abstract— In this study, an apparatus for basic physiological signal acquisitions sent to Could for monitoring
and computation has been designed and implemented. The basic physiologic signals included user’s
temperature, breath rate, and heart rate. The Bluetooth communication technology was employed to connect
between the microcontroller module and notebook computer or smart phone. The recurrent neural network
was employed to precisely detect the respiration rates. Through the measuring of thermistor, the accuracy isover 90% for breath rate. The range of temperature error was 0.5℃. The previous output of the neuron
network feedback and weighting averaged with new input. The method is precise. However, the complex
neuron network should be discussed in the future work for improving the accuracy of the system. The
uncertain of computations was affected by the selections of computing durations. Because the raw data has
been converted to values of heart and breath rates, the communication volume between client and cloud canbe much reduced, as well as this technology can be employed for the other physiological signals to elevate theperformance of this system in the near feature.
