A novel blood pressure monitoring device for ubiquitous healthcare services.

Hypertension is a world wide issue, and it is now generally accepted that its diurnal pattern has a prognostic significance. The purpose of this study is to develop a novel blood pressure (BP) monitoring device that causes less discomfort and is less disruptive of users' daily activities than conventional ambulatory blood pressure monitoring (ABPM) devices. The proposed device is worn at an ear orifice and measures BP at the tragus.
