| 總結: | In recent years, design of biomedical devices gains more significance to monitor, diagnose, and prevent various diseases without any disturbance to human subjects thus resulting in less hospital expenses. In this work, a generic cost-effective three electrode bio-signal acquisition device is designed and developed. Further, the acquired bio-signals, namely, electrocardiogram, electromyogram, and electrogas-trogram are analyzed using Fast Fourier Transform (FFT) and the peak frequency is estimated. Also, the decision support along with the acquired signal is stored and displayed remotely using the IoT framework. Results demonstrate that the proposed device is capable of measuring various bio-signals such as ECG, EMG, and EGG in a cost-effective way. Also, the IoT framework helps to monitor three different physiological signals in a remote manner using smartphones/computers. This work appears to be of high clinical relevance since physiological signals along with deci-sion support help the physician/caretakers to monitor health conditions remotely using IoT. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.
