Designing a Wearable Companion of Smartphone for Healthcare
Wearable devices are increasingly gaining more attentions in healthcare industry due to their potentials to measure valuable physiological signals on the move. There are many researchers who have proposed different types of designs that embed biosensors into miniature wearable devices. In this paper, we present a wearable companion that monitors the cardiac activities of a wearer with Smartphone. The device makes of use a single, integrated biosensor that is designed with a unique analog front-end circuitry and a dedicated signal processing pipeline. In order to meet the requirements of possible but different user scenarios, three types of product forms are presented. The experimental results show that electrocardiogram (ECG) signals collected are valid and consistent. Future topics include adding extra algorithms to removal motion artifacts in order to achieve better signal quality in various settings and include wireless communication through 4G.
