Abstract

In this study, a belt type wearable terminal was developed to measure subject’s biomedical signal and transmit the data to remote medical server. The terminal was developed to measure and record biomedical signal continuously in daily life and transmits the data to remote server through CDMA celluar network and informs remote doctor in emergent situation. It consists of three parts, such as, biomedical signal acquisition, data recording, and transmission part. Three experiments were performed to evaluate the accuracy, reliability and operability, applicability during daily life of the developed device. First, ECG signals were measured using the developed device and commercial reference device during sitting and cycle and compared to verify the accuracy of R-R intervals. Second, the reliable data transmission to remote server was verified on two types of simulated emergency event using patient simulator. Third, during seven types of motion in daily life, the accuracy of data transmission to remote server using CDMA network was verified on two types of event occurring. By acquiring and comparing subject’s biomedical signal and motion signal, the accuracy, reliability and operability, applicability during daily life of the developed device were verified. Therefore, the developed system is expected to play an important role in constructing the domestic ubiquitous healthcare system in the near future.KeywordsCDMAECGbelt typeubiquitous healthcare
