“…Table 4 presents the results obtained for the 42 registers recorded during the experimental stage. The true-positive (TP), truenegative (TN), false-positive (FP) and false-negative (FN) results were applied to calculate the positive predictivity (16), negative predictivity (17), sensitivity (18), specificity (19), positive F1 score (20) and negative F1 score (21). Positive and negative refer to the results obtained according to the predictions of stress and relaxation, respectively.…”

This paper proposes a reliable stress and relaxation level estimation algorithm that is implemented in a portable, low-cost hardware device and executed in real time. The main objective of this work is to offer an affordable and ''ready-to-go'' solution for medical and personal environments, in which the detection of the arousal level of a person is crucial. Methods: To achieve meaningful identification of stress and relaxation, a fuzzy algorithm based on expert knowledge is built according to parameters extracted from physiological records. In addition to the heart rate, parameters extracted from the galvanic skin response and breath are employed to extend the results. Moreover, this algorithm achieves accurate results with a restricted computational load and can be implemented in a miniaturized low-cost prototype. The developed solution includes standard and actively shielded electrodes that are connected to an Arduino device for acquisition, while parameter extraction and fuzzy processing are conducted with a more powerful Raspberry Pi board. The proposed solution is validated using real physiological registers from 42 subjects collected using BIOPAC MP36 hardware. Additionally, a real-time acquisition, processing and remote cloud storage service is integrated via IoT wireless technology. Results: Robust identification of stress and relaxation is achieved, with F1 scores of 91.15% and 96.61%, respectively. Moreover, processing is performed using a 20-second sliding window; thus, only a small frame of context is required. Significance: This work presents a reliable solution for identifying stress and relaxation levels in real time, which can lead to the production of low-cost commercial devices for use in medical and personal environments.

“…In [4] a device is developed in addition to a mobile application only to observe the signals obtained, however they do not have the remote evaluation that we have; in [5] a circuit capable of carrying out ECG and EMG readings is developed but they do not have an application or the possibility of an evaluation or remote by specialists; in [8] they developed an ECG acquisition system, through a mobile application to observe the results and finally a connection via Wi-Fi to a PC where the results can also be observed, compared to this work, our development does not have the connection to a pc, but if it has synchronization with a data server, from which the results obtained in the tests carried out can be observed.…”

“…A study at the Universidad Autónoma de Baja California indicated: Universities and institutes around the world have worked on these systems and although they differ in physical, technological or operational characteristics, they all meet the same objective: to record the ECG. Examples of these systems are those developed by companies such as The LifeSync® System, Nordic Semiconductor and Shimmer; also, they have included within their projects the design and implementation of device capable of obtaining the ECG wirelessly [8]. The signals that are collected by the three electrodes on the chest according to the standard positions of the Einthoven triangle, are taken to a circuit in charge of amplifying and filtering them, and then transferring to the Arduino UNO board.…”

Cardiac complications are caused by an unbalanced diet, the consumption of alcohol, smoking tobacco, in addition to the excess of polluting gases such as carbon dioxide (CO2), among other gases that are harmful to the human body, due to these types of problems, they arise more frequently in people, which lead to heart problems at an early age. An optimal prevention of these cardiac abnormalities is necessary using an Electrocardiogram (ECG), by using this equipment it is possible to detect the cardiac anomalies that the person may have, thus giving early prevention for cardiac abnormalities that may be occurring in the patient. The design of a low-cost ECG will be considered using the AD8232 module, which allows recording the electrical activities of the heart, obtaining an ECG using the Arduino, in addition the Bluetooth module will send the data collected from the ECG from a patient to a cellphone which will store this information, to be later analyzed by a cardiologist. This paper is intended for use in health campaigns, given that according to the Pan American health organization, 70% of deaths in the world are due to heart problems, due to this figure, it is expected to reduce the rate with early prevention, which consists of the implementation of this biomedical equipment in health campaigns that will have the basic functionalities for the analysis of the electrocardiogram and that is low cost compared to biomedical equipment currently that provide the same functionalities.
