As the life expectancy of individuals increases with recent advancements in medicine and quality of living, it is important to monitor the health of patients and healthy individuals on a daily basis. This is not possible with the current health care system in North America, and thus there is a need for wireless devices that can be used from home. These devices are called biomedical wearables, and they have become popular in the last decade. There are several reasons for that, but the main ones are: expensive health care, longer wait times, and an increase in public awareness about improving quality of life. With this, it is vital for anyone working on wearables to have an overall understanding of how they function, how they were designed, their significance, and what factors were considered when the hardware was designed. Therefore, this study attempts to investigate the hardware components that are required to design wearable devices that are used in the emerging context of the Internet of Medical Things (IoMT). This means that they can be used, to an extent, for disease monitoring through biosignal capture. In particular, this review study covers the basic components that are required for the front-end of any biomedical wearable, and the limitations that these wearable devices have. Furthermore, there is a discussion of the opportunities that they create, and the direction that the wearable industry is heading in.

<div>Taekwondo is a combat sport that is based on striking and involves full body contact. Initially, it a referee-exclusive sport and that led to increased controversy on referee/judges’ accuracy, bias and fairness. To address these concerns, point scoring systems (PSS) were introduced in 2012 only consisting of a chest protector and in 2016 head protectors were added. Constant improvements have been made on these PSS and new impact classification algorithms and hardware were developed for a system made by 20/20 Armor. The work achieved 90% accuracy for illegal vs legal classification on the head protector and 94.4% accuracy between legal impacts to the chest protector. This work proved to be a great step forward since reliance is increasing on these PSS as they are now the “final decision” for impact detection in Taekwondo. Furthermore, our algorithms use edge computing that allow for real time application and at-home training.</div>
