The three-lead wireless ECG in sensor networks for mobile patients

Telemedicine is a future trend of medical care due to the increasing cost of treatment and the aging of population around the world. Several telecommunication technologies are proposed for transferring medical data between a point of care and a hospital; however, full mobility of patients needed to be attached with wired monitoring devices is not provided. In this paper, we proposed a wireless three-lead electrocardiogram (ECG) device using a mote-based wireless sensor network (WSN) to transfer heart signals from a patient to a personal computer for monitoring and storing. Our device is designed using low-cost, low-power components, and provides full mobility to patients by eliminating noise from patientpsilas movement.
