SUMMARY:

Vital signs monitoring is one of the most recommended strategies by health professionals for control, patient’s triage and prognosis assistance of chronic or infectious diseases. The remote mass acquisition of physiological parameters of patients in clinical or residential environments, when efficiently managed, can provide valuable information about trends in epidemiological outbreaks in district, municipal, state, national or international regions. In this way, the main objective of this work is to use scientific consolidated technologies and methodologies to make the vital signs monitoring accessible to the user with only a smartphone in an effective, low-cost and easy way to use. This work presents the development of low-power wearable devices enabled with the NFC (Near Field Communication) technology, in a bracelet format, capable of simultaneously measuring heart rate, temperature, blood oxygen saturation and blood pressure in a non-invasive, comfortable and real-time way. Through a comfortable analog system for arm-wrist ECG acquisition, the device is capable of perform cuff-less measurement of blood pressure through PAT (Pulse Arrival Time) and heart rate parameters. A dynamic NFC interface was also developed, with simultaneous wireless transfer of data and energy between the passive prototype and a smartphone. Moreover, a graphical user interface and an online data log were developed for simultaneous monitoring of four vital signs, through a smartphone and the semi-passive prototype. A data collection protocol was developed with volunteers with approval of the ethics committee for studies with human beings (CAAEs: 24617219.4.0000.5208 and 45209121.2.0000.5208). Such data were used to validate the vital signs acquired by the prototypes with calibrated commercial equipment and evaluate the usability of the developed system by the volunteers. In accordance with clinical and scientific standards of reliability, validations were carried out through statistical analysis of the differences between the data acquired by the prototypes and the commercial equipment. Among the results, there were measurements of vital signs within the recommended clinical standards after prototypes optimization, whose averages and standard deviations of the acquired errors were e_BPM=0.0±1.22, e_SpO2=0.2±0.63%, e_Temperature=0.4±5.1 ^oC, e_SBP=0.3 ±5.1 mmHg, e_DBP=0.7±4.23 mmHg.  In addition, the proposed system was highly acceptable and well evaluated by the interviewed volunteers.
