By using these technologies, people have transformed the way they live, interact with each other and their surroundings, their daily routines, and how they monitor their health conditions.
We review recent advances in the area of wearable sensing technologies, focusing on aspects such as sensor technologies, communication infrastructures, service infrastructures, security, and privacy. We also review the use of consumer wearables during the coronavirus disease 19 COVID pandemic caused by the severe acute respiratory syndrome coronavirus 2 SARS-CoV-2 , and we discuss open challenges that must be addressed to further improve the efficacy of wearable sensing systems in the future.
Wearable sensing technologies continue to improve rapidly with advances in sensors, communication technologies, and artificial intelligence AI in the past decade. Research and development in wearable sensing technologies are fueling a revolution in the creation of novel services in gaming, fitness, entertainment, and specialized applications in industries such as healthcare, security, and defense, among others.
In , the market for wearable devices was USD 80 billion, which has tripled in terms of annual revenue since and it is expected to reach USD billion by [ 1 ]. Ear-worn wearables, in special hearables such as true wireless stereo TWS wearables, have surged from almost zero market share to a significant share of the wearable device market [ 1 ] since the introduction of Apple AirPods in , and have significantly increased during the coronavirus disease COVID pandemic [ 3 ], caused by severe acute respiratory syndrome coronavirus 2 SARS-CoV-2 , as many people have worked and studied from their homes worldwide.
