Low-power Technologies for Wearable Telecare and Telehealth Systems: A Review

다국어 초록 (Multilingual Abstract)

Wearable telecare and telehealth systems are those which canbe worn on the human body and continuously monitor auser’s vital status. Even though these systems have alreadyshown promise in applications for improving medical servicequality and reducing medical costs, a short battery lifesignificantly restricts the widespread use of these systems.
Low-power technologies (a general name for technologieswhich use various approaches to reduce the power consumptionof the associated electronics) can help alleviate thisdisadvantage of wearable telecare and telehealth systems. Inthis paper, we review recent developments and applicationsof low-power technologies in wearable telecare and telehealthsystems, sorting the various approaches into two categories:hardware-based approaches and firmware-based approaches.
This paper focuses on illustrating how to realize theseapproaches but does not provide a quantitative analysis ofdifferent approaches, since the intended applications of theseapproaches are quite different, hence numeric comparison isnot meaningful. Given the proliferation of wearable telecareand telehealth systems, there will be a greater emphasis onthe development of low-power technologies in this field.
