A comprehensive analysis of different types of proximity sensors in wearable electronic devices

Abstract

As the technological world has developed exponentially in recent decades, wearable electronics has been a growing industry in both size and significance. Sensors play an important role in these electronics, but research was rarely done on how different sensors play this role and serve different purposes. Thus, this paper focuses on the characteristics, pros and cons, and potential application on wearable electronics of different commonly seen proximity sensors. Namely, infrared sensors, ultrasonic sensors, and binocular vision. The research is done by analyzing different past papers and studies, piercing this information to gather to gain a comprehensive analysis and conclusions. The study reveals the vastly different characteristics of different proximity sensors and their different advantages and disadvantages displayed due to their diverse characteristics. The study also revealed potential applications of different sensors on wearable electronics. It is reasonably induced, from this study, that wearable electronics should adapt to use the most suitable proximity sensor and even use more than one type of sensor to tact the disadvantage of each to maximize its function.
