RESUMEN
Wearable sensor technologies have improved people's daily lives through their applications in almost every field. Sensor technologies of inventive kinds are used in an extensive variety of applications in lifestyle, healthcare, fitness, manufacturing, etc. There have also been crucial issues in making significant improvements to the actual mechanical, electrical, and optical sensing methods mainly in upgrading the precision of identification of wearable sensors to various stimuli. With an extensive study of the basic demands in wearable device technology as of now, the road map becomes clearer for creating greater innovations in the future. This is a review that gives an outline of types of wearable sensors by the score that is utilized in daily life. © 2023 IEEE.
RESUMEN
Having a good heart rate is important for a long lasting life and it is very important to monitor the heart rate of a person systematically. During this covid pandemic, it is highly necessary to monitor the pulse of a patient who is affected with covid. In order to keep track of the heart rate it is difficult to visit the hospital every time. Also, the available methods causes discomfort to the patients and these methods are very costly for a normal person. Piezoelectric pressure sensors are replacements for such highly expensive diagnosis systems. These sensors are easily accessible, have low cost and has high robustness. Since they give rapid responses to the input, it is widely used for medical, industrial and aerospace applications. This paper aims in designing and simulating a model of piezoelectric pressure sensor in COMSOL Multi physics platform satisfying the patients need of comfort and the figure of merits of pressure sensor. © 2022 IEEE.
