Abstract
Abstract This paper introduces a survey on recent smart wearable devices used in different fields, especially healthcare applications. A discussion is presented in terms of power supply, wireless technologies, applications, and wearability of these devices. Regarding the power supply, a photovoltaic is the best harvesting energy source, while the best energy storage is a Li-ion battery. Regarding wireless technologies, Bluetooth low energy (BLE) is the best for personal usage, while Wi-Fi has preferred for Internet of Things (IoT) applications. Regarding the applications, medical and non-medical applications can be used. Regarding wearability, smart wearable devices can be positioned on a human hand or arm. Also, wearable sensors can be patched on human skin, besides, they can be placed on clothes, such as a smart suit which is preferred for heavy duties.
