Smartphone-Based IoT Healthcare Monitoring System for Vital Signal Analysis and Remote Patient Care

Advancements in information and communication technologies have brought about a profound transformation in the realm of healthcare. The downsizing of signal acquisition devices has facilitated greater portability, yet this development has also presented challenges in terms of power consumption. To surmount this, a solution that is lightweight and power-efficient becomes imperative. One such solution involves harnessing the capabilities of smartphones to collect and analyze vital signals. Leveraging Internet of Things (IoT) technology enables the remote monitoring of diverse patient parameters, accessible through a range of devices such as computers and smartphones, facilitated by cloud services like ThingSpeak. Diverging from conventional tests, modern sensors, encompassing metrics like heart rate, temperature, and SPO2, provide daily readings that empower doctors to remotely prescribe treatments and exercises, thereby elevating the quality of life for patients. This innovative system offers instantaneous sensing, precise prognostications, and swift responses, culminating in streamlined healthcare practices that alleviate the burden on medical practitioners. Instances of anomalies prompt alerts to caregivers. The trajectory of this approach portends further enhancements, encompassing additional modules such as blood pressure monitoring and dental screening, to engender a comprehensive, real-time patient care continuum. This paradigm represents a notable stride towards the augmentation of patient care systems.
