Vital Signs Monitoring based on a Developed Accelerometer Sensor for Sporty Purposes

Abstract

This paper proposes developing a wireless sensor for heartbeat and respiration rate monitoring for the sportsman.The developed wireless sensor, includes an accelerometer sensor, a processor and a transceiver which operates in Industrial, Scientific and Medical (ISM) band and the frequency of 2.54 to connect with a central node for transmitting the measured data. In order to evaluate the accuracy of the presented sensor, the different experiments are carried out on several volunteers and the resultant data are compared to a gold standard for respiration rate and also heartbeat as a reference. As the outcomes illustrate, the root means square error (RMSE) and the standard deviation of the error (SD) are calculated less than 2.8 and 1.43 beats per minutes as well as 1.01 and 0.85 breaths per minutes for the heartbeat and respiration rate, respectively. Therefore, the sensor can account a good alternative for cardiorespiratory system monitoring for sporty application, due to low-cost, portable and also availability.

A Battery‐Less Arbitrary Motion Sensing System Using Magnetic Repulsion‐Based Self‐Powered Motion Sensors and Hybrid Nanogenerator

“…The rapid growth of the Internet of things (IoT), wearable electronics, and autonomous systems has increased the demand for the use of multiple sensors to achieve real-time control and acquisition of useful information. Among the various types of sensors, inertial motion sensors are in high demand because of the emerging fields of robotics control, [1][2][3] computer gaming, [4][5] automotives, [6][7][8] sports, [9][10][11][12][13] activity Moreover, the reported sensors are not perfectly applicable to arbitrary parameter detection (all direction sensing is not fully realized), have limited functionalities, and are confined to specific motion conditions (only linear, rotational, or tilting motion sensing capability). Thus, realizing a completely self-powered arbitrary motion sensing system with full functionalities on a single device with adequate accuracy is a major challenge.…”
