Simple Measurement System for Biological Signal Using a Smartphone

Abstract

<p>This paper describes simple measurement system for biological signal using smartphone. The proposed system consists of an instrumentation amplifier, a filter and an AC/DC converter. The biological signal is converted to the digital data through the microphone terminal with A/D converter in the smartphone. In many cases, the circuits require the power sources such as the cell batteries, however, the proposed system is supplied the power through the earphone terminal of the smartphone. Therefore, the proposed system no require the batteries. The software of this system parallelizes the processing so that the earphone output and the microphone terminal can be executed at the same time. The proposed system was verified through the measurement of surface electromyogram using discrete parts and iOS. Results of experimentation, the proposed system was operating correctly.</p>

Evolution of Microcontroller-based Remote Monitoring System Applications

“…The useful electrical signal with the aid of an algorithm parallelizes the process and can execute the output of earphone analog signal and microphone terminal at the same time. The experimental results demonstrate that the presented scheme operates properly [35].…”

The use of information technology applications in the provision of health care to a COVID-19 patients

“…As we mentioned previously, the use of information technology applications as well as electronic platforms to communicate and provide consultations and treatment for Corona patients remotely represents a practical and appropriate option in the face of this pandemic. However, the success of using these means needs to provide conditions represented in providing an integrated infrastructure for information technology, training the medical staff to use these technologies, an amendment to the hospital's work mechanism, and taking into account the privacy of patients [20]. Accordingly, this paper discusses the social, technological, and organizational factors that influence the use of information technology applications by clinicians and patients alike.…”
